Software with a point of view.

I design and build the apps people use every day, and the systems behind them, from the first screen to production.

  • React Native
  • Swift
  • Next.js
  • Kotlin
  • TypeScript
  • Go
  • PostgreSQL
  • Amazon Web Services

React Native

The React Native engineer you call for the hard parts.

I design, build and rescue React Native apps for iPhone and Android, from the first screen down to the native code beneath it, and advise teams before they commit to an architecture.

Book a consultation
  • Architecture reviewsA second opinion before you build.
  • Native integrationsConnect any native SDK or phone feature to your app.
  • Performance auditsFind what makes your app slow, then fix it.
  • Upgrades and rescuesBring an ageing app up to date without stopping work.

A sales team that sells on the move.

  • Card terminals cost money, run out of charge and get left at the office.
  • The payment provider’s SDK is made for iPhone and Android, not for React Native.
  • Their app is React Native, and it should stay one codebase.

Now every phone is the terminal.

The customer taps their card on the rep’s phone, and the sale is paid on the spot.

Four layers behind one tap.

Each layer has a job. Mine is the custom native module that connects your React Native app to the payment provider’s SDK.

  • React Native appThe checkout your team uses, built once for iPhone and Android.
  • Custom native moduleThe part I build: it connects your app to the payment SDK.
  • Payment SDKThe payment provider’s certified code for iPhone and Android.
  • NFC chipThe phone’s own card reader, so there is no terminal to buy.
