01
The problem
Elivate needed one wallet that worked the same on the web and on a phone. Every release meant a manual build, a manual check and a long wait, so small fixes sat in a queue for days and nobody wanted to ship on a Friday.
02
The approach
- One TypeScript API in Node.js in front of PostgreSQL, so the web app and the mobile app read the same balances and the same rules.
- Money stored as whole cents, never as decimals, so a balance adds up the same way on every screen and in every report.
- A pipeline that tests, builds and deploys every merge on its own, with a one-click rollback if anything looks wrong.
03
The result
A merge now reaches production in 95 s instead of 14 minutes. Fixes go out the same afternoon they are written, and releases stopped being an event.
Shipping became the boring part, which is how it should be.
