Віталій Калініченко

I'm a backend developer who builds complete, tested systems rather than tutorial-style prototypes. My anchor projects are Cerberus, a statistical-arbitrage trading bot for Polymarket (Python, asyncio, WebSockets, SQLite, 106 automated tests, 72-hour live paper-trading validation), and Project Sentinel, a mean-reversion bot for Bybit with an XGBoost confidence layer (FastAPI, Docker, PostgreSQL, 64 tests).

What I care about most is honest evaluation: during Cerberus's validation I found and fixed critical bugs that were inflating the strategy's apparent performance, and reported the real result — a small negative edge — instead of a flattering number. I'd rather ship something rigorously tested and honestly reported than something that looks better than it is.

I use AI coding tools (Claude Code) as part of my daily workflow, but always review and understand what they generate. Alongside my Applied Physics degree, I'm completing an intensive .NET development track, with my main focus on Python/FastAPI backend roles.
