I work in TypeScript on both ends of a production IoT platform: the Next.js dashboard partners use and the NestJS APIs behind it. I own that platform's cloud side end to end, so the same work also covers the database, the message pipeline and the deployments. Most of what I know came from running that system, not only from adding features to it.
Own the cloud side of a multi-tenant IoT platform end to end: the partner dashboard, the API, the message pipeline, and the deployments. It runs at a few million API requests a day with tens of thousands of concurrent MQTT connections.
A Roux speedcubing trainer that reads a Bluetooth cube as you turn it. The awkward part is that the cube has six sensors and none under the middle layer, so a written M arrives as two face turns plus a rotation nothing can sense, which the app has to track itself or every step after the first slice asks for the wrong face. Timing, step splits and per-case statistics come off the live move stream, and a websocket relay drives OBS overlays and bridges a phone’s radio to the desktop.
A guided crystal-growing app for children: step-by-step programs, a private photo diary, and a gallery a moderator approves. Access rules live in Postgres row level security rather than in the application, so a route cannot leak another child's diary. Installable as a PWA.
A Model Context Protocol server for IoT cloud platforms, so an assistant can query and control devices through one interface rather than a separate integration per platform.
Feedback on a handwritten maths problem. A computer-algebra engine decides whether a step is right and the model only writes the explanation, so it cannot invent a correction that is wrong.
A long-form writing tool. The awkward part is that prompt cost grows with the story, so it keeps a canon store, a rolling summary and vector retrieval instead of resending history.
