Bohdan Senkiv

Python Developer with commercial experience in building Telegram bots and automation scripts. I specialize in the aiogram library, API integrations, and database management.

My core strength is the ability to quickly grasp documentation for new services (CRMs, Payment Systems) and translate requirements into working code. I write clean, typed code using the asynchronous approach (asyncio). I am proficient in containerizing projects with Docker and deploying them to servers. Looking for challenging projects to grow professionally.
