Software engineer in Groningen, Netherlands.
I reverse engineer devices, publish the client, and ship the Home Assistant integration.
Most of what I publish follows one shape. I find a device or a service whose API nobody wrote down, work the protocol out of the app that talks to it, publish a clean async Python client, then build a Home Assistant integration on top of that client. The client stays useful on its own, so the next person does not have to repeat the hard part. Three integrations are in the HACS default store and three more are in review.
The rest of my time goes into the platform that runs all of it at home: a Proxmox cluster and NixOS hosts, the whole configuration in one flake, deployed by a script that shows dry activation, runs the tests, switches, and then checks that the host reports the revision it was given.

- tuya-mobile reimplements the Tuya mobile app security layer in pure Python, so a camera answers to my own code instead of the vendor app.
- switchMCP puts a homebrew Nintendo Switch behind MCP, which lets an agent manage it over the network.
- remote-for-xirp is a mobile web control surface for a coding agent daemon.
- hevy-api-knowledge documents the Hevy workout API, both the public v1 and the one the app actually uses.
