I build and extend maintainable Symfony backends for web platforms and business applications. Typical work includes: • Symfony modules, services, events and console commands • REST APIs and third-party system integrations • MySQL/MariaDB data models and query optimization • Authentication, validation, error handling and logging • Background jobs, Docker, Git and CI/CD workflows • Code reviews, tests and technical documentation I start by clarifying architecture, interfaces and priorities, then deliver in small, verifiable steps.
