01/If this sounds familiar

The reality of brownfield RN.

If you’re running React Native inside a legacy native app, you’ve probably hit this:

  • Upgrades that should take a sprint take a quarter
  • Build times creeping past 20 minutes and nobody knows why
  • A native bridge that’s "mostly fine" until it isn’t
  • Native and RN engineers working past each other instead of with each other
  • Performance complaints from users your dashboards can’t explain
  • A path to the New Architecture (Fabric, TurboModules) that nobody on your team has time to map

You don’t need another generalist mobile consultancy. You need someone who actually works in brownfield React Native every day.

05/About

Who runs PittsDev.

PittsDev is run by Ben Pitts, a senior React Native engineer who has spent years working in brownfield mobile codebases — RN running inside production native iOS and Android apps with real users, real release pressure, and real tech debt. This isn’t a side practice. It’s the work.

Most React Native consultants build greenfield apps from scratch. PittsDev does the harder, less glamorous job: making the React Native you already have actually work.

06/FAQ

Common questions.

01How is this different from a regular code review?
A code review tells you whether your code is well-written. The audit tells you whether your React Native integration is serving the business — release velocity, build times, native bridge stability, upgrade posture, and where engineering hours are leaking. The output is decisions to make, not nits to fix.
02Do you need full repo access?
Read-only access is enough. I don’t push branches and I don’t touch production. If repo access is a procurement bottleneck, we can scope around a sanitized export plus structured walkthroughs with your team.
03What if our codebase is bigger than the Standard tier covers?
Then it’s a Plus or Strategic engagement. The intro call is partly a sizing exercise — I’ll give you an honest read after looking at the surface area. Tier upgrades are agreed in writing up front, never mid-engagement.
04Do you implement the fixes?
Sometimes, but not by default. The audit is decoupled from implementation so you can act on it with your own team, another vendor, or me. If you want me to lead the highest-impact fix afterward, that’s a separate engagement scoped from the report.
05How soon can we start?
Usually within 2–3 weeks of the intro call. I keep one audit slot booked at a time so you get a senior practitioner’s full attention, not a parallel-projects rotation.
06Why fixed price instead of hourly?
Hourly billing optimizes for hours, not outcomes. Fixed price means you know what you’re paying before you start, and I’m paid to deliver the report — not to drag it out. If the work runs long, that’s my problem to solve.
