Things I have built that made it to the finish line. Some are still alive, some are not, but all of them worked.
A macOS app that gets downloaded videos ready to play on a TV. It probes every track in the MKV and remuxes to MP4, stream copying H.264 video and AAC or AC3 audio untouched, transcoding only what the TV cannot decode, and demuxing text subtitles to .srt.

A self-hosted music player: your own library instead of a subscription, running off a Raspberry Pi 4 at home. Invite-only, with passkeys or a password to get in. Three clients over the same library: a web app, a native Android client in Kotlin, and Android Auto in the car. Mine holds over two weeks of uninterrupted music.

A recommender for Google Stadia: you rated the games you had played and it suggested what to play next, based on what people with similar taste enjoyed. It ran until Google shut Stadia down.

Small things I extracted from my own projects and published on npm.
Scroll edge indicators for React. Shows shadows or solid lines on the edges of a scrollable container to hint there is more content, using IntersectionObserver instead of scroll events.
Color coded logger for JavaScript and TypeScript that works the same in the browser and in Node, with buffers and source persistence to keep the noise down without losing context.
Headless tabs for React built on the Activity API, so hidden panels keep their state instead of unmounting. Switch away from a tab and come back: scroll position and inputs are still there.
