One time-tracking product across web, desktop and mobile

About the client
TraxStaff is a time-tracking product for teams. Time is recorded against a project and a task as the work happens, and the record is organised by day, week and project rather than dropped into one long list.
The brief
Build the product on every surface a team actually works on (a browser, a desktop machine and a phone) without three separate codebases drifting apart, and with roles and permissions that hold the same in all three.


The approach
One API behind three clients. The dashboard is a Next.js application, the desktop client is Tauri so it ships as a native binary rather than a bundled browser, and the mobile client is Expo. The server is Fastify over Prisma and Postgres, so every client reads the same data through the same rules.
Most time-tracking tools feel like extra work, so teams stop using them after two weeks. This one stayed simple enough that supervisors still see daily entries.
