Projects

Six that are worth reading about, and six more underneath. Open a row for the detail and the part that was actually hard.

Real time train overview

building2026

Live trains, S-Bahn, trams and buses on a desktop map, drawn on top of the operator's own network map.

The network map the vehicles are drawn on. Placeholder.

Vehicles moving along their lines. Placeholder gif.

gif

It started as a Berlin viewer on the VBB map, then moved to Magdeburg and the INSA map. Vue 3 and Leaflet on the front, Rust inside the Tauri process on the back. The Rust commands proxy the HAFAS JSON gateway and normalise the response into plain vehicle positions with a line, a mode, a bearing and a coordinate.

the hard part

INSA has no public API. Live positions come from the JourneyGeoPos method on reiseauskunft.insa.de/bin/mgate.exe, the same radar call the hafas-client insa profile uses. Figuring out the auth and the request shape was most of the work.

Python pre-course

shipped2026

An interactive deck for OVGU's Python pre-course, where every idea starts as a small story with Momo the cat and ends as Python the room runs in the browser.

Everyday decisions land one by one, then turn over into the same if / then / else pattern.

gif

Momo's door: the story plays out both ways, becomes pseudo-code, then Python.

gif

Why loops: comparing every fish with every other gets out of hand, so Momo walks the basket once instead.

gif

The look started from two references, the restraint of 3Blue1Brown and the flat pastels of Jet Lag The Game, and became a small system: white slides, JetBrains Mono, bold colour blocks, 2px borders, no shadows. Motion is state, never decoration. Animations were sketched in Manim, then rebuilt in CSS inside the slides. Every lesson runs the same way: a problem for the cast, the idea as a picture, the same idea as pseudo-code, then Python, with the surviving words sliding into place. Each stage is its own slide that opens on the last frame of the one before, so it plays as one scene. Around that: a phone remote over a QR code, a presenter view, puzzle rounds with leaderboards, a live Cat API request, a sound layer and a Comic Sans reading mode. Tools: Nuxt 3, Vue 3, Tailwind 4, Pinia, Nitro WebSockets, Pyodide and CodeMirror, with headless Chromium and ffmpeg rendering these gifs from the deck.

the hard part

Making a lesson feel like one continuous animation while every step is still its own slide that a phone, a projector and the presenter can each land on. And rendering it to video frame by frame on a virtual clock, so a slow machine still gives a smooth result.

Nuxt 3Vue 3Tailwind 4PyodideWebSocket107 commitsmore

jobot

live2024 to 2025

Market making and arbitrage bot for high frequency, real time cryptocurrency trading.

Not one script. A TypeScript monorepo with a CEX library, a DEX library, a liquidity system, a quote system, its own logger, a SEI node in Docker and a web dashboard that streams live logs over WebSocket. Configs live in a database, trade history is downloadable, and there is a rebalancer for when a swap fails.

the hard part

Keeping quotes and liquidity correct while three exchanges disagree about the price, and making the thing keep running when one of them stops answering.

TypeScriptNodeDockerWebSocketSEI277 commitsmore

guppi

building2026

A general purpose hub. A Rust control system that tools connect to, a web editor, and pluggable frontends.

The control system owns config, Google OAuth and data, and exposes a REST API and a WebSocket. The first frontend is a multi monitor screensaver with a clock, Google Tasks and a black and white calendar. Designed so future tools bolt on: if I need a tool, I make it and connect it.

the hard part

The name is from the Bobiverse, General Unit Primary Peripheral Interface. Naming only, not theming. The UI is deliberately minimal, pure black and white, a normal font, no sci-fi skin.

RustaxumeguiVue 3Tailwindmore

verteilte

live2025 to 2026

A spaced repetition flashcard app built for personal use, to accelerate German acquisition.

Verteilte is German for distributed. You type your answers instead of flipping a card, so the recall is real. Smart input handles the language specific characters, ae becomes ä as you type. Runs on Linux and Android from one codebase, and syncs progress across devices through a Node and PostgreSQL backend.

Tauri 2Vue 3TypeScriptPostgreSQLPiniamore

Finsternis

shipped2026

Ludum Dare 59. A robot that cannot see directly and navigates on radar sweeps and echolocation.

Top down character scroller. The player relies on the periodic sweeps of their own radar towers, or on short range echolocation, to navigate. Harvest resources, build and upgrade more towers, enemies wait further out.

the hard part

The rendering respects the sensor constraints. Everything is drawn in an abstract sonar style: wireframe, black and white, sound waves reflecting off the actual geometry. 2.5D with simple shapes, because the detail is hidden by the sonar anyway.

arbeit-radar

live2026

German job aggregator. Scrapes the major boards, stores everything in SQLite, translates to English.

Six boards: Indeed, StepStone, Arbeitsagentur, Monster, LinkedIn and Glassdoor. Over eighty search terms, German and English paired across specialisations. Per site rate limiting with jitter and exponential backoff, cross platform deduplication so the same job posted twice is caught, raw HTML kept for reference, and a Vue dashboard to browse it.

TypeScriptPuppeteerSQLiteVue 36 boards, 80+ termsmore

presentation-Template

live2026

Presentation framework where the remote is a QR code and the deck is a set of routes.

Scan a QR code and your phone moves the room. Speaker notes sync to the remote in real time, a presenter view shows the live slide, the next slide, a timer and where the audience is. Every slide keeps an id such as PRE-0004 for its whole life, so reordering never renames a file or a route.

Binance, KuCoin and OKX data across nineteen shards. Written in Go. ClickHouse and QuestDB were benchmarked first before settling on Timescale.

Every pixel is black or white. The document is a flat array of sections, each one a rule, a bar or text, and the whole thing is a single Vue file with no dependencies beyond Vue and Vite.

About

I started coding during the Covid lockdown with Minecraft modding in Java. Two years of that, then JavaScript, then TypeScript and Nuxt, and now most of the interesting work happens in Rust and Go.

The pattern I keep noticing: I like the projects where the system was not built for me to use. An undocumented transit API, six job boards that would rather not be scraped, three exchanges that disagree about a price. The code is rarely the hard part.

Linux is my primary OS and Neovim is where I work. I maintain my own servers. I build my own tools when the tool I want does not exist, which is how a CV compiler and a general purpose hub both happened.
