Backend Python Developer specializing in scalable FastAPI services and performance optimization.
What I'm looking for
I am a Backend Python Developer with over two years of commercial experience building and maintaining FastAPI-based services. I focus on designing, developing, and optimizing scalable backend architectures for TravelTech and related domains.
At Avia Center I refactored legacy systems, improved API performance fivefold, accelerated booking processes by 40%, and redesigned integrations to reduce expert request time. I also designed and built a chat system to streamline client-supplier communications.
I develop with strong attention to database design and reliability, working with PostgreSQL, MySQL, MsSQL, MongoDB and Redis, and applying OOP, SOLID principles and microservice patterns. I containerize applications, set up CI/CD pipelines, and manage database migrations and schemas.
I contribute to open source (UFO Delivery), lead system design discussions, and collaborate closely in cross-functional teams to drive time-to-market and deliver robust, maintainable backend solutions.
