About me
👋 I'm Jan Schejbal, a Full-Stack developer with experience building web and mobile applications. I focus mainly on TypeScript, JavaScript and React.
I enjoy solving technical problems, learning new technologies and working on real projects that have a positive impact on people's lives. I bring AI into my workflow responsibly and meaningfully, so I can work more efficiently and deliver higher-quality solutions.
As lead developer I drove the development of the StepanEvent system and the HobbyLiga mobile app, and led a team on an AI project for healthcare using a locally hosted LLM and RAG. Day to day I work with React, Next.js and React Native on the frontend and Node.js on the backend; I also have solid foundations in PHP (Nette) and Python.
