Native App Development — iOS, Android & Flutter

Twelve years of shipping native mobile apps to the App Store and Google Play. I build in Swift and SwiftUI on iOS, Kotlin and Java on Android, and Flutter when a single codebase is the right call — with the architecture, offline handling and performance work that keeps an app healthy long after launch.

What you get

  • iOS apps in Swift and SwiftUI, built to current platform standards.
  • Android apps in Kotlin and Java, or Flutter when one codebase makes sense.
  • Architecture that holds up: clean layers, offline support and predictable state.
  • Performance work — smooth scrolling, fast startup, sensible memory use.
  • App Store and Play releases handled, including review submissions and rejections.

How it works

  1. Shape it Agree scope, platforms and architecture before writing feature code.
  2. Build Implement in focused iterations with working builds you can try.
  3. Harden Offline, edge cases, performance and accessibility passes.
  4. Release Ship to the App Store and Play, and handle the review back-and-forth.

A good fit if

  • You need a real native app, not a wrapped website.
  • You want one engineer who can take iOS and Android from architecture to store.
  • You've been burned by an app that shipped fast and aged badly.

FAQ

iOS, Android, or both?

Either or both. Native per platform when it matters, Flutter when a shared codebase saves time without hurting the experience — we decide together.

Can you take over an existing app?

Yes. I'll usually run a short audit first so I understand the codebase before changing it — see the auditing service.

Do you handle store submissions?

Yes — build, signing, submission and the review process, including handling rejections when they come.
