Home-lab tinkerer — automating the house, one sensor at a time.
I like making the systems in my house talk to each other — locks, sensors, radios, dashboards — and I usually end up building the missing piece myself. Most of it runs on a small fleet of self-hosted boxes, held together with Home Assistant, MQTT, and more YAML than is probably healthy.
A Home Assistant sensor for exposing real-time deadbolt lock/unlock status, shared as a community how-to.
A terminal dashboard for watching MQTT traffic in real time — like top, but for the smart home.
An RTL-SDR dongle feeding a Home Assistant Bond RF Sync add-on, so RF remotes for fans and shades show up as normal HA entities.
Reading an analog gas meter two ways — computer-vision dial parsing and RTL-AMR radio decoding — both feeding Home Assistant.
A clinical trials finder with a mobile app and a web admin CMS, so patients can search for studies they might qualify for.
A WWII Pacific flight sim built from scratch for the browser on WebGPU — a flight model checked against published trial data, flown over terrain built from real Leyte Gulf geography.
