Technologies & Tools

I work with tools that excel in projects requiring stability, automation, and high quality. I connect the server layer, backend, frontend, and integrations to create end-to-end solutions: from architecture and data, to implementation and maintenance.

Backend and Databases

  • PHP (OOP / Procedural) – web systems, APIs, integrations, automation, high-performance modules.
  • Java (J2EE / Servlets / JSP) – business logic, internal integrations, enterprise-class systems.
  • SQL (MySQL, PostgreSQL, Microsoft SQL Server, SQLite) – database design and optimization, multi-table queries, views, procedures, ETL.
  • Scripting & Tooling (Python, Bash, C++) – parsers, migrations, data processing, anomaly detection, AI model integrations (LLM / ML).

Frontend and presentation layer

  • HTML5 / CSS3 (RWD) – semantic, fast and responsive layouts.
  • JavaScript / jQuery – dynamic interfaces, AJAX, validations, front↔back logic.
  • Bootstrap – rapid prototypes and stable components.

Frameworks, CMS and e-commerce

  • Laravel – ETL / ELT processes, data aggregation, building Data Hubs, API, task automation, queue systems.
  • Symfony (components) – API, routing, validations, server logic, microservices.
  • WordPress – dedicated themes, plugins, ACF, automation, integration with business systems.
  • PrestaShop – modules, ERP integrations, product and stock synchronization.
  • WooCommerce – shops, payments, warehouse management, automation.
  • Magento / Joomla / Drupal – installations, configurations, template modifications, administration.

Servers and IT infrastructure

  • Linux (Debian / Ubuntu / CentOS) – service configuration, security, monitoring, performance.
  • Windows Server / Active Directory – domains, GPO, permissions, DNS/DHCP, security policies.
  • Apache / Nginx / LiteSpeed – configurations, performance optimizations and cache.
  • Hosting / VPS / Dedicated Servers – implementations, migrations, prod/dev environments.
  • SSL, DNS, e-mail, domains – configuration and management of services.
  • VPN (OpenVPN / IPSec / SSL VPN) – tunneling, secure remote access.
  • Computer Networks (CCNA) – small/medium network configuration, routing, diagnostics, security.

DevOps, automation and ETL processes

  • Git – workflows, versioning, code review.
  • Docker – application containers, environment consistency, deployments.
  • Composer / Maven – dependency and build management.
  • PHPUnit, JUnit, Selenium – unit and E2E testing.
  • Cron / schedules / post-deployment scripts – backend and business process automation.
  • ETL / data integration – CSV/XLS/XML transformations, automatic imports and exports.

Monitoring, security, maintenance

  • Server and application monitoring – availability, resource consumption, alerts.
  • Backups and DR procedures – full copy and restore policy.
  • Security and configuration testing – best practices, hardening, risk analysis.

Technical SEO and Performance

  • Performance optimization – cache, minification, lazy loading, compression, image optimization.
  • Technical SEO – data structures, HTML semantics, loading speed, browser compatibility.
