Available to hire
I’m Andrei Sukhanov, a senior Python developer and technical lead with 15+ years of experience building backend products, API integrations, event-processing flows, and data-heavy systems across Django, FastAPI, SQL-heavy platforms, and enterprise software. I love researching new APIs and engineering scalable ways to collect, process, and derive insights from data.
I’m open to freelance opportunities and enjoy solving complex backend challenges—from designing robust event-processing pipelines to building multi-tenant data models and secure access controls.
