About
I am a Python Backend Developer from Brest, Belarus. I like building systems that are simple enough to operate, but strong enough to survive real production traffic: APIs, admin tools, integrations, data pipelines, background workers, and AI features with clear boundaries.
I enjoy the engineering space where backend code meets the physical world: networking, hardware-adjacent products, computer vision, video processing, and operational tooling. I have worked on restaurant platforms, media workflows, ClickHouse analytics, Telegram bots, parsing systems, payment features, and computer vision for buffet hardware.
