Here I list projects I developed while studying at FIT CTU. Some of them are my own personal project and some are assignments from university courses.
- See publications
- Menza CTU — Mobile client + server for viewing and rating CTU canteen menus (2000+ users, 50+ stars), Kotlin
- Menza backend — REST API based backend for the Menza app, Kotlin
- Lispík — SECD VM and compiler for Lisp constructs, Kotlin (2022)
- Mila — Pascal compiler to LLVM, Rust (2023)
- vimxel — Table processor in terminal supporting expressions and Vim bindings, C++ (2022)
- Vector house — Vector based search engine for Wikipedia, Python (2022)
- Multiple Discord bots in Kotlin, Go and Haskell
You can judge my code style based on the previous projects or based on some of my published assignments:
- Advent of Code repo (2023)
- C++ course repository (first grade — 2021)
- C course repository (first grade — 2022)
- Algorithms repository (second grade — 2022)
- Advanced Algorithms repository (second grade — 2023)
- and more minor projects
I'm running Alma Linux on my Raspberry Pi 4 hosting the services like my own rating backend for the Menza app, Nextcloud, Synapse Matrix, Syncthing, and WordPress. I use Docker compose for containerization and Nginx as a reverse proxy.
- Many small Android and Java apps
- Bakaláři mobile client (huge, but never finished & published)
- Arduino/ESP weather station
