Needed tiny deltas for an encrypted document format. Built xpatch with 7 specialized algorithms and a tag system that references old versions. Result: median delta of 2 bytes on real code repositories, tested on 1.2 million real-world changes.
TL;DR: Needed tiny deltas for an encrypted document format. xdelta3 uses 40+ bytes for simple edits....
An embedded audio playback system built during my apprenticeship — replacing a disruptive siren with dynamic sound effects powered by an STM32 microcontroller, SD card storage, and FreeRTOS.
A deep dive into building a compiler that translates C-like syntax into Brainfuck — exploring parser design, memory management on a tape machine, and the creative solutions needed when your target has only 8 instructions.
A TypeScript-native configuration system that unifies typed environment variables, code generation, and task management — because scattered .env files drive me crazy.
A command-line tool with a friendly TUI that automates tedious project setup tasks for TFBern electronics apprentices — and the journey from simple script to modular tool.
Charmer is a Go library that takes annotated functions and automatically builds a navigable TUI around them — removing the need to manually implement the UI for command-line tools.
Rewriting TFUtils in Go for better distribution and performance — and building the Charmer library along the way to make TUI-based CLI tools easier for everyone.
Building an open-source, privacy-respecting coupon browser extension — from designing the Go backend with PostgreSQL and Redis to becoming a maintainer on the project.
