What I'm looking for

I want to work on highload FastAPI microservices where I can optimize SQL and latency, build async task processing with Celery/RabbitMQ, and ship reliably with strong CI/CD, testing, and clean architecture.

I’m a Python backend developer focused on building scalable, testable REST APIs with FastAPI in high-load environments. I have 5+ years of experience designing and maintaining microservices, including systems handling up to 10k RPS.

I’m especially proud of performance-focused work: caching with Redis to improve API response times by 25–35%, and SQL optimization (CTE, window functions) that reduced execution time by up to 40%, including work with large data volumes. I also build async processing flows using Celery and RabbitMQ to handle thousands of tasks in parallel.

I deliver production-ready services end-to-end—middleware for logging/tracing and error handling, CI/CD with GitLab CI, and containerized deployments with Docker and Nginx. I keep quality high with pytest, Docker-based dev workflows, and strong database practices (PostgreSQL, Alembic, SQLAlchemy).
