A bit about me
I've been paid to write software for about three years. Mostly React for the first two. In the last year, more Go, Rust and Android than I planned for.
The work I like has a part that only shows up when things go wrong. A phone that lost signal. A device that retries forever. An email that must not go out twice. I like being the person who has already thought about that part.
At Wokay I own the task and chat modules of a real-time workspace, built the structure behind notifications, and now work on the geo module: live location tracking in React Native. Evenings go to the projects above.
