About
I am a 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.

readyCode Arena
Private coding rooms for friendly battles: invite people by room code, pick a challenge, wait until everyone is ready, then race to solve it before the timer runs out.

2 scores = data.split()[1:]
3 numbers = map(int, scores)
