A plugin that turns WordPress into a content backend for a Next.js front end: signed webhooks, a background queue, draft previews on the front end and a GraphQL cache served before WordPress even boots. Static pages respond about 35× faster than classic WordPress.

Extended Markdown with security built into the core: a tokenizer, parser, sanitizer and HTML renderer in TypeScript with no external dependencies, a NestJS integration, a WYSIWYG editor and a demo page. Anything not on the allowlist does not get through.

A Raspberry Pi Zero 2 W for a Golf IV: entry lighting driven by the door-lock signals, the only connection to the LED strip and an encrypted channel to the phone. A model checker verifies the logic across every reachable state; the gateway is now fitted in the car.

The target board for the Golf IV electronics: a Raspberry Pi Pico 2 W instead of a Pi Zero with add-on modules, a power stage that survives automotive transients, and every output on one board. The schematic and PCB are generated by scripts.
