Problem
Two mobile products needed a proper backend from day one — clear database structure, solid APIs, and data rules the apps could trust — not something patched together later.
Solution
Built both backends from scratch: designed schemas, implemented REST APIs, applied clean structure with design patterns, and covered critical paths with unit tests so the mobile teams could ship without fighting the server.
Result
Both apps launched on a stable API and database layer. Auth, core CRUD, and sync endpoints stayed reliable under normal production use, with fewer backend bugs after release because the important logic was tested.
