The problem
The same architectural mistakes. I have seen them all.
Across more than a decade of React Native engineering I have seen what poor code architecture does to a business and its users — and now I watch AI code generation struggle to perform against the same disorganised codebases.
The story
Built to solve a problem I kept seeing.
Made more powerful by AI code generation.
If Claude is writing your code, it can write it any way you tell it to… so why not show it how to write it well!
Tommy Harty
Technical Architect
I didn't set out to build an architectural system. I set out to fix the same problems I kept encountering across every React Native project — business logic tangled into UI, no consistent module structure, uncontrolled state, integrations with no abstraction layer. The same problems, in every codebase, at every scale.
So I built Clean React. A three-layer architecture that cleanly separates concerns, makes every integration swappable, and gives every feature a consistent, predictable structure. I introduced it on a production React Native app for a well-known health tech company. The team adopted it. The app now has five-star App Store reviews.
Then AI code generation arrived — and Clean React turned out to be exactly what LLMs need to perform at their best. Its contract-driven structure means small, focused agents can generate 80–90% of the codebase locally, at near-zero cost. Claude Code handles only the layer where repo-wide context actually matters.
Clean React was built to solve the architectural problems of the last decade. It turned out to also be the foundation for the most cost-effective way to build React Native apps in the AI era.
Brand new opportunity
Two things that make this unlike anything else in the market.
Clean React is two things working together — a gold-standard architecture that makes your codebase stronger as it grows, and an agentic workflow that makes building it remarkably fast and cost-efficient.
The outcome
A different commercial reality for your business.
The migration does not just clean up your codebase. It changes what your business is capable of.
How it works
A structured migration from your existing app to Clean React.
Every migration follows the same proven sequence — from mapping your existing app through to a fully rebuilt, production-ready React Native app with the agent workflow embedded and ready for all future development.
1. Discovery & Planning
We map your existing app — every UI pattern, every feature, every integration. From this we plan the UI library, the full feature architecture, and the spec structure that will govern the entire build.
2. Agent Build
Small, focused agents build the entire app against the Clean React architecture — every component, every feature, every integration — using the agent workflow. Clean React's contract-driven structure means 80–90% of the build runs locally at near-zero cost.
3. Staged Release
The rebuilt app is released first to a small percentage of users — validating performance, stability, and user experience before a full rollout to your entire user base.
4. Handover
Your team is onboarded onto the Clean React architecture and the agent workflow — leaving you with a production-grade app and the capability to build every future feature the same way.
