I am a Senior PHP / Symfony Full-Stack Engineer with 13+ years of experience building, modernizing, and supporting web applications. I help businesses improve legacy PHP systems, build reliable APIs and integrations, optimize application performance, and deliver maintainable features from backend to frontend. My core stack includes PHP 8.x, Symfony, Laravel, Doctrine ORM, MySQL, PostgreSQL, Redis, JavaScript, Svelte, Docker, and Nginx. I have worked on ERP and e-commerce systems, CRM modules, high-performance data processing, third-party integrations, and real-time services using WebSockets. I am especially effective when a project requires someone who can quickly understand an unfamiliar codebase, identify the actual source of a problem, and implement a safe, practical solution. I can help you with: • PHP and Symfony feature development • Legacy code modernization and refactoring • REST APIs and third-party integrations • MySQL and PostgreSQL performance optimization • Data processing, automation, and parsers • Docker-based development and deployment • WebSocket and real-time backend functionality • Investigation and resolution of complex production issues You will receive clear communication, maintainable code, and an honest assessment of the scope before major work begins.
