Mobile App Development.

iOS and Android that feel native rather than like a website in a shell. Cross-platform in React Native or Flutter when one codebase is the right call, fully native in Swift when it is not. I take it from first screen through App Store and Play Store review, including the parts most builds forget: push, offline, updates, and the release pipeline.

// app shapes

Four kinds of app, built on the runtime each one needs.

Cross-platform in React Native or Flutter, or fully native in Swift, depending on what the product actually needs. Below is what I build, and the stack behind it.

Marketplaces · dashboards

Companion app

Your web product, on a phone, doing the three things people actually open a phone for. Usually the fastest route to a store listing.

Trades · logistics · inspections

Field and on-site tools

Built for spotty signal. Offline-first data, background sync, camera and location where the job needs them.

Elderdoc · Handigwerk

Booking and marketplace

Two-sided flows with push at the moments that matter: a new request, a quote, a confirmation.

Readers · calculators · trackers

Consumer utility

One job, done fast, with no account wall in front of it. Small surface, high polish, quick review cycles.

What's included.

  • +Product and flow design for small screens, not a desktop layout squeezed down
  • +React Native and Expo, Flutter, or native Swift, chosen for the product
  • +Native-feel navigation, gestures, haptics, and platform conventions
  • +Push notifications, deep links, and offline-first data with sync
  • +Auth, in-app purchases or Stripe, analytics, and crash reporting
  • +App Store and Play Store submission, review handling, and over-the-air updates
// outcomes

What you can expect.

  • A shipped app on both stores, not a TestFlight build that stalled
  • The right runtime for the product, not the one I happen to prefer
  • A release pipeline your team can run without me
  • Crash and adoption numbers visible from the first release
// process

How an engagement runs.

01
Scope

Which platforms, which flows, and whether this is a cross-platform job or a native one. Most apps need less native code than the pitch assumes.

02
Prototype

The two or three screens that carry the product, running on a real device in week one. Simulators hide too much.

03
Build

Feature work against real devices on both platforms, with builds going out to testers continuously rather than at the end.

04
Ship

Store listings, review submission, and the rejection round that usually follows. Then over-the-air updates so fixes don't wait on review.

// best fit

Best for.

  • Web products whose users keep asking for an app
  • Founders who need both stores covered without hiring two mobile engineers
  • Teams with a stalled native build that needs finishing and shipping
// pricing

Engagement & pricing.

A focused first release runs 6 to 10 weeks. Adding mobile to an existing web product is usually shorter. Fixed scope, fixed price.
