Projects
A selection of my work — with the technologies, challenges, and learnings behind them.
Wossibel2Go — Crowdsourcing for a Folklore Archive
A web application for browsing and collaboratively transcribing the digitized Wossidlo card collection. Vue 3 frontend with an Express backend as a proxy to the WossiDiA API of the University of Rostock.
LED Panel — Spotify Album Cover on 64x64 Pixels
A Raspberry Pi drives a 64x64 RGB LED matrix and displays the album cover of the currently playing Spotify song — with automatic switching on track change.
Knowledge Graph — Interactive Content Network
An Obsidian-inspired knowledge graph that visualizes blog posts and projects as physically simulated, interconnected nodes.
CMS — Managing Content Without Learning Git
Why I chose Keystatic as the CMS for my portfolio and how it fits into the existing Astro infrastructure without creating a second source of truth.
Monitor — Server Dashboard
A dashboard for monitoring my server with real-time metrics, service management, container status, and a centralized log view.
mathis-adler.dev — Portfolio
My personal portfolio — statically generated with Astro, hardened with WireGuard VPN and Nginx, automatically deployed via GitHub Actions.
Once — One-Time Secrets
A one-time secret service with end-to-end encryption. Secrets are encrypted client-side with AES-256-GCM — the server never sees plaintext or keys.
QR Code & Short Link Toolkit
An end-to-end system for QR codes and short links — from a browser-based generator to a self-hosted redirect service to a CLI tool.
