One codebase, every platform
A product team needed to ship to web, iOS, and Android without staffing three separate app teams.
The constraint
The product needed to be everywhere — web, iOS, Android — but the team couldn’t afford to staff and coordinate three independent app teams. Three codebases means three sets of bugs, three release cadences, and three places every feature has to be re-implemented. They needed reach without that multiplier.
Architecture
We delivered a single foundation designed to target all three platforms from one source of truth:
- Shared React Native + web core. Business logic, navigation, and UI are written once and rendered natively on iOS and Android and as a web app, so a feature lands everywhere from one change.
- Auth and a customer portal out of the box. Authentication and the account/portal surface are wired in from day one — the unglamorous, time-consuming foundation that every product needs and no product wants to rebuild.
- A clean service API. The client app talks to a well-defined backend API, keeping platform code thin and the contract between app and server explicit.
The foundation wasn’t built from scratch — it’s extracted from patterns we’ve hardened across multiple products, so the team started on proven ground rather than a blank repo.
Outcome
One codebase ships to all three platforms, and the team started months ahead on the parts that usually sink early timelines: authentication, infrastructure, and CI. New features move at the speed of a single team, not three.
