Whatwedo

Maintenance and feature development
We take over a service that is already running, keep building features on it, and handle the problems that come up along the way.
Deliverables — Source code, handed over in your repository · A completion record for each feature · Test results · A working deployment environment
New build
We build a new service or a new app from the ground up. That includes putting a new channel — a mobile app, an admin console — on top of a system you already run.
Deliverables — Source code, handed over in your repository · Design mockups for the main screens · Test results · Build and deployment pipeline
