Summary
👤
Senior🎓
Top SchoolMichal Hořejšek is a versatile Python developer with 16 years of experience building full-stack and backend systems, currently focused on recommendation engines and deep learning at Seznam.cz. He has led teams, modernized legacy business applications (migrating to Flask and SQLAlchemy), and established testing, CI and documentation practices that improved long-term maintainability. Comfortable across Python and JavaScript, he has hands-on experience from front-end UX work (contributions to notable web client projects) to performance-sensitive Cython and Couchbase integrations. Michal combines product-minded engineering—having built and run an end-to-end e‑book e‑shop—with curiosity-driven side projects (an “own RSS reader” exploring Haskell, Neo4j and data mining). Colleagues value his mentoring, pragmatic automation, and ability to turn prototypes into production-grade systems.
