Top SchoolYury Selivanov is a seasoned engineering leader and Python core developer with 17 years of experience, currently directing engineering at Vercel and advising startups as an Entrepreneur in Residence. He co-founded MagicStack and Gel Data (EdgeDB), blending founder-level product judgment with deep systems expertise in databases, asyncio, and language internals. A prolific open-source contributor and Python Software Foundation fellow, he helped design async/await, asynchronous generators, and execution context PEPs and regularly contributes to CPython and popular projects like asyncpg and gevent. His hands-on work spans byte-string compatibility, buffer and connection management in high-performance Postgres clients, and developer tooling such as MagicPython. Based in San Francisco, he combines CEO-level strategic experience with low-level engineering chops—often improving performance and ergonomics in the Python runtime itself. An unexpected detail: beyond leadership roles he still commits core fixes and tests, demonstrating a rare mix of product leadership and day-to-day code craftsmanship.
