04 / PERSONAL PROJECTS

Curiosity continues
after work.

01 / LOCAL AI APPLICATION

Text becomes speech.
On my own GPU.

AI Reader reads Markdown files aloud, one sentence at a time. I built the application with a React interface, Node/Express and a Python worker. Qwen3-TTS (12 Hz, 1.7B, Base) runs locally on my RTX 3090 using PyTorch and CUDA.

The model stays in memory. Upcoming sentences are generated in advance, and a WAV cache avoids repeating synthesis. Controls cover navigation, speed, section pauses and live audio adjustments. An online voice provides a fallback while the GPU is unavailable.

Language model training

A personal learning project using freely available training data to explore the training process through to initial text generation.

  • React / TypeScript
  • Node / Express
  • Python
  • PyTorch / CUDA
  • Qwen3-TTS
02 / GAME DEVELOPMENT

A garden of my own.
Built from code and ideas.

Mahjong Garten is an offline-capable Mahjong Solitaire game for web and mobile platforms. It includes game logic, solvable layouts, progression, a customisable garden and local saves.

I develop the game with TypeScript, Vite and Capacitor.

  • TypeScript
  • Vite
  • Capacitor
  • Offline / local data
03 / DESKTOP APPLICATION

From a Bluetooth signal
to training results.

A local Windows application for DISAG RedDot, capturing, processing and scoring shooting-sport data over Bluetooth.

Training and competition management, statistical analysis, and printing results and certificates. Data stays in a local SQLite database, with backup and restore.

  • React
  • TypeScript
  • Tauri
  • Rust
  • SQLite
  • Vite
View code / RotPunktArena
04 / PERSONAL KUBERNETES LAB

My own small universe.
Room to experiment.

Run a personal k3s environment with game servers and Nextcloud, and occasional hosting of my own website.

A place to operate technologies myself and explore how they work together.

  • Kubernetes
  • k3s
  • Self-Hosting
  • Nextcloud
IN PRACTICE / AI AS A TOOL

Experiment.
Build understanding.

Local model integration and AI-assisted development in personal projects.

I use Codex, Cursor, Claude, OpenClaw and Hermes for research, ideation, refinement and implementation in my personal projects. AI Reader combines this development practice with running a speech synthesis model locally.

05 / FOUNDATIONS & LEARNING

Precision meets
curiosity.

My path began in machining. Today, I work with systems.
