Profile

Czech informatics student at FI MUNI, with three systems in real use: the internal system a tutoring company runs on daily, a school e-commerce platform, and an open-source npm package. I work across the whole stack in TypeScript - from the PostgreSQL schema to Docker and the Linux server it runs on.
