Web survivor game I shipped at school. Waves of enemies, leaderboard, vibes. Go die a few times.

🕹 Web game · Live
Swarmaggedon
Browser-based survivor game I built at school. Waves of enemies, a shared global leaderboard, and enough chaos to keep friends fighting over high scores on a friend's VPS. Mine is at allanbrunner.dev too.
🏎 Online multiplayer · Scala
ISCRacer
Online multiplayer racing game on top of a custom LibGDX2D Scala wrapper I wrote as a layer over the Java lib. Mode7 perspective rendering, physics engine, and full online — all built from scratch. Yes, that Mode7.

QTTT — Quantum Tic-Tac-Toe
Tic-tac-toe but each move places a mark in superposition across two squares simultaneously. The board collapses when an entanglement loop is detected. It sounds mad. It makes total sense when you play it.
🔧 Compiler · PL theory
YAFL — Yet Another Functional Language
A custom functional programming language designed and implemented in pure Scala (functional paradigm only — no side effects allowed, yes this was painful and enlightening). Compiles to WebAssembly.
📖 Interpreter · Following the book
Lox Interpreter
Built the Lox language from Robert Nystrom's Crafting Interpreters — twice. First a tree-walking interpreter in Java, then a bytecode VM in C. One of the best things I've done to understand how languages actually work.

Something with stars
Before I finish my IT degree, I want to start bridging into astrophysics through projects — simulations, maybe relativistic stuff, maybe something no one asked for. TBD. The universe is a big place.
I live in the Alps. When the code isn't compiling I go up a mountain. When it is, I still go. Running every week — building toward a 100k trail race before chasing the IronMan finish line before 2030.
Finishing my bachelor's in Big Data & AI, then applying for a Master's in Astrophysics. I want to understand the universe the same way I understand a codebase — from first principles, all the way down.
Chemistry and quantum physics are where the really weird stuff lives. Molecular orbitals, superposition, entanglement — I'm obsessed with the layer of reality where classical intuition breaks down completely.
I laugh at everything, build random things for the joy of it, and am genuinely convinced that not taking yourself too seriously is a superpower. Life's better when you're having fun doing everything and nothing at once.
Living life with my girlfriend and a great group of friends — some of whom also happen to run VPS servers for my game projects. That's how you know they're keepers.
Compilers at school, games on weekends, trail runs at 6am, astrophysics papers before bed. Controlled chaos. I like it here — there's always something interesting to be bad at before getting good at it.

🎸 & everything else
I go to festivals and hard techno / hardstyle parties when I'm not on a trail or debugging at midnight. Also: chilled concerts for the slower nights. The playlist range isn't a personality disorder — it's called being a human with taste.
Hard SF that respects the science and isn't afraid to go dark with it. Currently haunted by Solaris — Lem's ocean isn't really about alien contact, it's about the impossibility of understanding anything truly other. A book that asks whether science can ever reach far enough. Exactly the kind of question I like.
Solaris deserves a second mention here too. It's one of those rare books that uses a SF premise to go somewhere philosophy textbooks can't — the limits of human cognition, the arrogance of assuming contact is even possible, the loneliness built into consciousness itself. I like books that make me feel slightly unsettled about existence.
Currently reading the Temeraire series by Naomi Novik — Napoleonic warfare, but with dragons treated as seriously as real military history. The worldbuilding is meticulous and the dragon-human relationships are genuinely moving. Fantasy done right: the magic has weight, and the world has rules.
Yep. I'm secretly writing a book. It's fiction. That's all I'm saying for now — genre, plot, and existence all technically unconfirmed. If you ask me about it in person I'll either tell you everything or deflect with a joke. Probably both.
🤫 classifiedWhether it's a big data problem, a game jam, a debate about quantum mechanics, or just a trail in the Valais — I'm easy to find.
