Hire a Mobile App Developer
Senior mobile engineer across Flutter, iOS (Swift), and Android (Kotlin). 17+ apps on the App Store and Google Play. Based in London, working worldwide.
Why Hire Me
What you get when you bring me onto your project.
Three Stacks, One Developer
Flutter for speed, Swift/SwiftUI when iOS needs native depth, Kotlin/Compose when Android demands it. I pick the right tool — not the only tool I know.
Deep iOS Expertise
SwiftUI, UIKit, AVFoundation, HealthKit, CoreML, WidgetKit, Live Activities. Comfortable with Xcode, TestFlight, App Store Connect, and provisioning drama.
Modern Android
Jetpack Compose, Material Design 3, Coroutines + Flow, Room, Hilt, WorkManager. Play Store releases with staged rollouts and crash monitoring.
Performance & Battery Conscious
I profile before I guess. 60fps animations, low APK/IPA size, smart background work, minimal network traffic — your users will notice.
App Store & Play Store Veteran
Metadata, screenshots, ASO basics, phased rollouts, subscriptions, IAPs, in-app review prompts. I have shipped and recovered from rejection notices.
AI-Ready Mobile Apps
On-device ML (CoreML, TFLite, ONNX) plus cloud LLMs. I add AI features to mobile apps that respect privacy, battery, and your API budget.
Mobile Tech Stack
The tools, libraries, and patterns I use every day.
When to Hire Me
Common scenarios where clients bring me in.
Ship Your First Mobile App
Idea to App Store in 6-10 weeks. Full-stack: design, build, backend, deployment.
Cross-Platform Migration
Separate iOS + Android codebases? Consolidate to Flutter and cut your maintenance cost in half.
Native App Rescue
Half-finished Swift or Kotlin project? I pick it up, refactor the mess, and ship it.
Add AI to a Mobile App
Drop GPT, Claude, or on-device ML into your existing app without degrading UX or battery.
Performance Optimization
App slow? Battery draining? APK bloated? I profile and fix — measurable improvements guaranteed.
App Store / Play Store Submission
Hit a rejection? ASO not working? Subscriptions confusing? I navigate the storefront gauntlet.
My Process
From first call to launch — here is how we work together.
Discovery
Deep-dive call to understand your goals, users, and constraints. I ask the hard questions early so we ship the right thing.
Design & Architecture
Wireframes, data models, and tech stack locked in. You review and sign off before a single line of code.
Build
Iterative sprints with weekly demos. You always know what's shipping — no black box, no surprises at the end.
Test & Refine
Automated tests, device matrix, performance profiling. We catch issues before your users ever see them.
Launch & Support
App Store submission, deployment, monitoring. I stay available for fixes and iteration after go-live.
