SUMMARY
Backend developer with over 4 years of experience in commercial PHP development. I specialize in designing REST
APIs, integrating third-party services, working with message queues (RabbitMQ), and database design (PostgreSQL,
MySQL/MariaDB). I have experience refactoring legacy code, optimizing SQL queries, and setting up containerized
environments (Docker Compose). In my work, I focus on clean code (SOLID, DRY), strict typing, and leveraging the modern
features of PHP 8.x.

Comfortable with technical documentation, text-based async communication, and code commenting in English.
