Problems We Solve
For over 26 years, we have been managing Linux infrastructures, hosting platforms and software development projects, addressing issues involving operating systems, network services, email systems, databases, web applications and platform integrations.
When a problem affects multiple layers of an infrastructure, a single area of expertise is often not enough. Understanding how servers, services, databases and applications interact is essential to quickly identify the root cause and restore the proper operation of the entire system.
Email Deliverability and Professional Email Systems
We provide configuration, analysis and troubleshooting services for issues related to professional email systems, message delivery and outbound mail server reputation.
Our services include the configuration and verification of SPF, DKIM, DMARC, PTR records, blacklist monitoring, IP reputation analysis, SMTP relays, Exim configuration, log analysis and troubleshooting of deliverability issues.
"Why do emails end up in spam even when the server is working correctly?"
The causes can be numerous and are not always related to the mail server itself. The most common issues involve SPF, DKIM, DMARC, PTR records, IP reputation, public blacklists, incorrect SMTP configurations or content considered suspicious by spam filtering systems.
"Are SPF, DKIM and DMARC sufficient to guarantee email delivery?"
No. Although they are essential, they represent only part of the process. IP reputation, DNS configuration, sending history and message quality directly affect deliverability.
"Why can a newly registered domain experience delivery problems even when SPF, DKIM and DMARC are configured correctly?"
Email providers do not evaluate only the technical configuration of a domain. Domain age, IP reputation, sending history and recipient behaviour directly influence deliverability. Even with a correct configuration, a new domain may require a warm-up period before reaching optimal delivery rates.
"Why are some emails delivered correctly to Gmail but rejected by Outlook or Microsoft 365?"
Each provider uses different algorithms and criteria to evaluate the reliability of incoming messages. A configuration accepted by Gmail may not be sufficient for Microsoft 365 or Outlook. SPF, DKIM, DMARC, PTR records, IP reputation, message content and domain history are evaluated differently by each provider.
"Why can an email end up in spam even when SPF, DKIM and DMARC are configured correctly?"
SPF, DKIM and DMARC represent only part of the checks performed by email providers. Spam filtering systems also analyse the content of the message and assign a score (spam score) based on numerous factors.
Factors such as invalid HTML code, excessive use of images, potentially risky attachments, links pointing to low-reputation domains, shortened URLs, words commonly associated with spam, the absence of a plain-text version of the message or incorrectly configured email headers can increase the score assigned by spam filters.
Even when SPF, DKIM and DMARC are perfectly configured, a high score may cause the message to be classified as spam or limit its delivery to providers such as Gmail, Outlook or Microsoft 365.
Linux Infrastructure and Hosting
We manage Linux infrastructures designed for production environments and professional hosting platforms, from initial server deployment via SSH to the configuration of core services.
Our services include cPanel/WHM installation and administration, Apache configuration, PHP-FPM optimization, MariaDB tuning, DNS management, dedicated VPS administration, security hardening, backup strategies, disaster recovery planning, service monitoring and advanced troubleshooting.
We also design redundant DNS infrastructures using cPanel DNS Only clusters, allowing DNS zones to be distributed across multiple servers and ensuring greater reliability and business continuity even in the event of a primary server failure.
"Why can a Linux server be slow even when CPU and RAM are not fully utilized?"
Server performance does not depend solely on CPU and memory resources. Inefficient SQL queries, poorly optimized Apache or PHP-FPM configurations, DNS latency, slow storage, blocked processes or poorly designed applications can all cause performance issues even when system resources appear to be available.
"When should a DNS cluster be used instead of a single nameserver?"
A DNS cluster allows DNS zones to be automatically distributed across multiple servers, increasing infrastructure reliability. In professional hosting environments, this approach is commonly adopted to reduce the risk of DNS service outages and improve operational continuity.
"What is cPanel DNS Only and when is it used?"
cPanel DNS Only is a dedicated version of cPanel designed exclusively for DNS services. It is frequently used to build distributed DNS clusters, allowing WHM servers to automatically replicate DNS zones to remote nameservers without requiring full cPanel licenses.
"Why can a website become slower after being migrated to a new server?"
Migrations involve many different components, including DNS, PHP configurations, software versions, databases, caching systems and operating system services. Even when data has been transferred correctly, configuration differences can significantly affect application performance.
"Apache, PHP-FPM or MariaDB: how can you identify the real bottleneck?"
In many situations, the component that appears to be causing the slowdown is not the actual source of the problem. Analysing logs, system resources, running processes and SQL queries makes it possible to identify the service that is truly limiting infrastructure performance.
Performance and Optimization
When an application becomes slow or unstable, the issue can be caused by multiple factors. Focusing exclusively on the source code is rarely sufficient to identify the real cause of performance degradation.
We analyse infrastructure, services, databases and applications, working on Apache, PHP-FPM, MariaDB, DNS, Cloudflare, SQL queries, server configurations and application bottlenecks with the goal of improving performance, stability and response times.
"Can Cloudflare make a slow website faster?"
Cloudflare can improve the delivery of static content and reduce latency for end users, but it cannot fix problems caused by inefficient SQL queries, incorrect server configurations or poorly optimized application code. A slow infrastructure will remain slow even behind a CDN.
"Does adding more CPU and RAM always solve performance problems?"
No. In many situations, the issue is caused by incorrect configurations, inefficient queries, blocked processes or architectural limitations within the application. Increasing resources without identifying the real cause of the slowdown often results in higher costs without delivering meaningful improvements.
"Why can an application be slow even on a very powerful server?"
Performance depends on the entire application stack. Poorly optimized databases, slow external services, DNS issues, third-party APIs, misconfigured caching systems or inefficient code can all generate slowdowns regardless of the available hardware resources.
"How can you determine whether the problem is the database and not the server?"
Analysing queries, indexes, execution times and database statistics makes it possible to determine whether MariaDB or MySQL is the actual bottleneck. In many cases, the server has sufficient resources available but is slowed down by inefficient queries or poorly optimized tables.
"Why can an application become slower over time without any apparent changes?"
Increasing data volumes, growing traffic, log accumulation, changes in external services or infrastructure modifications can progressively affect performance. Even without application updates, system behaviour can change over time and require analysis and optimization activities.
PrestaShop
For many years, we have been developing custom solutions for PrestaShop-based e-commerce platforms, working on both functional requirements and integrations with external systems.
We develop custom modules, integrate APIs, automate business processes, synchronize catalogs and data from external systems, implement front-office and back-office customizations, and provide maintenance, upgrade and performance optimization services.
"Why can PrestaShop become slower as the number of products increases?"
PrestaShop performance does not depend solely on the number of products in the catalog. Server configuration, SQL queries, installed modules, images, caching, search functionality and external integrations can all significantly impact the response times of the entire e-commerce platform.
"Can PrestaShop be integrated with ERP systems, management software or other business applications?"
Yes. Through APIs, web services, XML files, JSON data exchanges or custom procedures, it is possible to synchronize products, categories, stock levels, orders, customers and other information coming from ERP systems, management software, marketplaces or proprietary platforms.
"When is it better to develop a custom module instead of using a commercial one?"
Commercial modules are often a quick solution for common requirements. When business processes require specific features, unique integrations or custom logic not supported by standard modules, custom development provides a more efficient and fully integrated solution.
"Why do some modules stop working after a PrestaShop update?"
Each new PrestaShop release may introduce changes to classes, hooks, database structures or internal processes. Modules developed for previous versions may require updates or adjustments to maintain compatibility with newer releases.
"Is it possible to automate repetitive tasks within PrestaShop?"
Yes. Catalog imports, price updates, stock synchronization, order management, data exports and many other processes can be automated through custom modules, API integrations and scheduled procedures, reducing operational time and minimizing manual errors.
WHMCS and Service Automation
WHMCS is one of the leading platforms used in the hosting industry for customer management and service automation.
We develop custom modules, licensing systems, automated provisioning procedures, integrations with third-party services and custom workflows designed to automate operational processes, reducing manual tasks and minimizing the risk of human error.
"Is it possible to fully automate the activation of hosting services?"
Yes. WHMCS can automate the entire provisioning process, from customer registration to the activation of hosting accounts, VPS services, domains, SSL certificates and other products. Automation reduces management time and minimizes operational errors.
"When is it necessary to develop a custom WHMCS module?"
Custom modules become necessary when business processes cannot be managed through WHMCS standard features. Integrations with proprietary platforms, licensing systems, custom provisioning procedures and specific operational workflows often require dedicated development.
"Can WHMCS be integrated with external software and third-party APIs?"
Yes. WHMCS provides APIs and hooks that allow integration with external platforms, ERP systems, payment gateways, monitoring solutions, cloud services and proprietary applications, enabling the automatic synchronization of data and business processes.
"What is a licensing system and how can it be integrated with WHMCS?"
A licensing system allows software activations, renewals, suspensions and license validation checks to be managed automatically. When integrated with WHMCS, it enables both the commercial and technical management of software products to be automated.
"Why automate operational processes through WHMCS?"
Automation reduces manual tasks, processing times and human errors. Operations such as activations, renewals, suspensions, notifications, provisioning and data synchronization can be executed automatically, improving the overall efficiency of the infrastructure and the services provided to customers.
System Integration
Many companies use different software platforms that often do not communicate with each other. This results in repetitive manual tasks, data duplication and unnecessary time loss.
We develop integrations between ERP systems, e-commerce platforms, marketplaces, cloud services and proprietary software using REST APIs, JSON, XML and custom procedures designed to automate business workflows and synchronize information across different systems.
"Is it possible to connect software platforms that do not provide native integrations?"
Yes. Through APIs, web services, XML files, JSON data exchanges or custom procedures, it is possible to create communication flows between different platforms, enabling the automatic exchange of information even when official integrations are not available.
"What types of data can be synchronized between different systems?"
Products, categories, stock levels, orders, customers, invoices, shipments and many other types of information can be automatically synchronized between e-commerce platforms, ERP systems, marketplaces, CRM solutions and business applications, eliminating manual tasks and reducing the risk of errors.
"REST APIs, XML or JSON: which technology should be used?"
The choice depends on the characteristics of the platforms involved. REST APIs are currently the most widely adopted standard, while XML and JSON are commonly used for structured data exchange between systems built on different technologies.
"Why automate data entry across multiple software platforms?"
Entering the same information manually into multiple systems increases the risk of errors, requires additional time and slows down business operations. Automation keeps data aligned and up to date while significantly reducing repetitive manual activities.
"How can integrations be managed when dealing with proprietary software or incomplete documentation?"
Many integrations involve internally developed applications or systems that do not provide complete technical documentation. In such cases, it is necessary to analyse existing workflows, understand the underlying data structures and develop custom procedures capable of ensuring reliable information exchange.
Software Development
We develop custom web applications for companies and professionals who require tools designed around their operational needs rather than standardized processes.
The technologies we use include PHP, CodeIgniter, Laravel, Smarty, JavaScript, HTML5, CSS3, REST APIs, JSON and XML. Every project is developed with a strong focus on stability, maintainability and seamless integration with existing infrastructures.
"When is it better to develop custom software instead of using an existing solution?"
Standard solutions are often the best choice for common requirements. However, when business processes require specific features, unique integrations or operational workflows that are not supported by available software, custom development provides a solution that truly matches the company's needs.
"Is it possible to develop software that integrates with existing systems?"
Yes. Applications can be designed to communicate with existing databases, ERP systems, e-commerce platforms, marketplaces, CRM solutions, cloud platforms and third-party services through APIs, web services and custom integration procedures.
"How can the future growth of an application be ensured?"
A well-designed application should be able to evolve over time without requiring a complete rewrite. For this reason, particular attention is given to software architecture, code modularity, maintainability and the ability to integrate new features in the future.
"Can repetitive business activities be automated through custom software?"
Yes. Many manual activities can be automated through dedicated procedures, reducing operational time, data entry errors and management costs. Automation also improves process reliability and the quality of the information being handled.
"Why is infrastructure important in software development?"
The performance, security and reliability of an application depend not only on the code itself but also on the environment in which it runs. Direct experience with Linux systems, databases, web services and hosting infrastructures makes it possible to develop applications designed to operate efficiently within production environments.
Mobile Applications
We develop Android and iOS applications integrated with web platforms, business systems and remote services, allowing users to access company data and functionalities directly from mobile devices.
Our solutions are built using Flutter, Dart and Firebase and may include push notifications, data synchronization, API integrations and connectivity with existing platforms.
"Is it possible to connect a mobile app to ERP systems, e-commerce platforms and business software?"
Yes. Applications can be integrated with ERP systems, e-commerce platforms, CRM solutions and proprietary software through APIs and web services, allowing users to access and update data directly from mobile devices.
"When is it better to develop a mobile app instead of using a standard web application?"
Mobile applications are particularly beneficial when there is a need for quick access to specific features, push notifications, native device capabilities or an improved user experience compared to a traditional web application.
"Can Android and iOS applications share the same codebase?"
Yes. By using Flutter, it is possible to develop cross-platform applications while sharing most of the source code, reducing development time, lowering maintenance costs and ensuring functional consistency across Android and iOS devices.
"How do push notifications work and when are they useful?"
Push notifications make it possible to send real-time messages to users even when the application is not open. They can be used for operational updates, order confirmations, promotions, technical alerts, reminders or any event that requires immediate communication.
"Is it possible to automatically synchronize data between a mobile application and existing platforms?"
Yes. Through APIs and remote services, products, orders, customers, documents, statistics and virtually any other business information can be synchronized automatically, keeping data aligned between mobile applications and existing company systems.
Virtualization and Networking
Infrastructure-related issues do not involve servers alone. In many cases, networking, virtualization and perimeter security play a critical role in the overall stability and availability of services.
We have hands-on experience with VMware environments, pfSense, VPS management, routing, firewalls, network segmentation and infrastructure troubleshooting, allowing us to address complex issues involving multiple layers of an IT infrastructure.
"Why can an application become unreachable even when the server is running correctly?"
In many situations, the problem is not related to the server itself but to the network. Firewall rules, routing configurations, DNS issues, VLANs, NAT settings or security devices can prevent access to services even when the operating system and applications are functioning properly.
"When is it beneficial to virtualize an infrastructure?"
Virtualization helps optimize hardware resource utilization, simplify service management and improve operational continuity. In many scenarios, it also makes it possible to separate different environments while maintaining greater flexibility in infrastructure management.
"What are the benefits of network segmentation?"
Network segmentation allows services, users and devices to be isolated from one another, reducing the attack surface while improving security, traffic control and overall infrastructure performance. It is a particularly important practice in business environments and professional hosting platforms.
"What is the purpose of a firewall such as pfSense?"
pfSense provides advanced management of access rules, VPNs, NAT, routing, traffic monitoring and numerous perimeter security features. A properly configured firewall helps protect Internet-facing services and provides detailed control over network traffic.
"How can an infrastructure issue be identified when there are no obvious errors?"
Many infrastructure problems appear through symptoms that seem unrelated at first glance. Analysing network traffic, logs, routing, firewall configurations, virtualization layers and the involved services makes it possible to identify anomalies that are not visible through standard application or operating system checks.
