Top SchoolJan Stránský is a backend developer and founder with 12 years of experience building API-first web platforms, especially in Node.js and JavaScript ecosystems. Based in Prague, he has led technical architecture and backend teams for social networks and web products, pairing GraphQL, MongoDB, Redis and ElasticSearch with robust DevOps practices like Docker, Ansible and FreeBSD administration. He currently develops at Dayswaps and runs OpenCrypto.io, blending hands-on backend engineering with product-focused entrepreneurship.
