Backend systems for
payments, Telegram and Web3.
Python backend engineer with 2+ years of project-based and ongoing employment experience. I build APIs, payment flows, booking systems, background jobs and Web3 integrations. I can deliver a complete product, including React / Next.js interfaces. My experience also includes building a voice AI assistant from scratch and working with GPU infrastructure.
Core Stack: Python 3.11+, FastAPI, AsyncIO, Dishka, PostgreSQL, Redis, SQLAlchemy 2.0, Alembic, Celery / ARQ, Docker
Work experience
Commercial work and independent development.
Python Backend Developer
Commercial Project (NDA) — AI Video & GPU Platform
- Architected and deployed an autonomous GPU agent on RunPod: parallel execution of compute workloads from backend queues with dynamic worker scaling.
- Implemented workload-driven container auto-scaling and graceful shutdown routines, reducing idle GPU infrastructure costs.
- Configured hardware-accelerated video rendering pipelines on NVIDIA and local LLM deployment; optimized batch image manipulation.
- Refactored integration services and eliminated queue processing bottlenecks, enhancing overall system fault tolerance.
