OLEG RUZIN

I combine two roles: I design the interface and then build it into a working product myself. As a freelancer I made websites and Telegram bots for the Rhinepay payment service and for Rhinestone Trading, a chemical raw materials supplier — both are live and used by real clients. Most of my code is written together with Claude Code: I know where AI genuinely speeds work up and where it has to be double-checked. Everything in this resume can be opened and tried — links are in the descriptions.
