Building software,
and the infrastructure
it runs on.

I'm Teodor — a second-year Computer Science student who takes initiative and likes building things people actually use. Most recently, a recruitment game played by 90+ students at TU Dublin's society fair, running on infrastructure I set up myself.

01 — Projects

Selected work

Things I've built and run in production — most of them outside of coursework.

Featured · Full-stack · CS++ Society

jumpflip

A Flappy Bird-style recruitment game I designed, built and deployed for the CS++ Society. It was played by 90+ students across 1,500+ games at TU Dublin's society fair, and students signed up to the society along the way.

Owned it end to end in production: Docker containerisation, Traefik and Nginx/HTTPS routing, health checks and persistent storage.
Scores can't be faked: the browser sends only the player's inputs, and the server replays the run to work out the score.
Password-protected organiser dashboard with search and CSV export, so student numbers never appear on the public screen.

Infrastructure · DevOps

homelab-stack

A self-hosted Ubuntu server on Hetzner running Docker Compose services (monitoring, a dashboard and a password manager) behind Nginx and Let's Encrypt, protected by UFW and Fail2ban. I learned by breaking things: Docker networking, health checks and a memory outage.

Python · AI

Tic-Tac-Toe

Tic-tac-toe against an unbeatable minimax AI. It started as a pygame app; I then split the game logic out behind a Flask API with a JavaScript frontend and containerised it with Docker.

Web app

typetest

A monkeytype-style typing test with time, word-count and infinite modes, live WPM and accuracy, personal bests per mode and 30 switchable themes. It uses no frameworks and has no build step.
