📱 MOBILE APPS, END TO END
I've spent 11 years building iOS and Android apps. Flutter is my main stack; I also build in React Native (Expo) and native Swift/Kotlin, with Firebase or Supabase behind them, and I handle App Store and Google Play releases myself: listings, signing, review, and the first week of crash monitoring.

🤖 AI FEATURES INSIDE YOUR APP
Chat assistants, voice and speech-to-text, OCR, smart recommendations, built into Flutter and React Native apps using OpenAI and Claude APIs, with usage limits and cost controls so your bill doesn't surprise you.

YOU'RE A GOOD FIT IF YOU'RE THINKING:
• "I have the idea and the designs; I need someone to build the first version and get it live."
• "Our app is live but slow, buggy, or stuck in App Store review."
• "A previous developer, FlutterFlow, or an AI tool got us halfway. We need it finished and published."
• "We need payments, subscriptions, maps, chat, or push notifications added without breaking what works."
• "We want a senior developer who can take over the codebase, not a team we have to manage."

STACK
• Mobile: Flutter, React Native (Expo), Swift/SwiftUI, Kotlin
• Backends for mobile: Firebase, Supabase, Node.js, Laravel
• Payments: Stripe, RevenueCat, in-app purchases and subscriptions
• Store and delivery: TestFlight, Play internal testing, GitHub Actions / Codemagic CI, Crashlytics

APPS I'VE SHIPPED

• Temple Bliss: live consultations with chat, audio and payments, 20K+ users
• JDiamond Qatar: jewellery e-commerce app, 12K+ downloads
• HitchHyke: ride-sharing platform, rider and driver apps plus dispatch, taken from MVP to live product
• 2026: a ride-hailing MVP for a US startup [client name with permission], a sports community app's feature and store updates [Softball Nation, with permission], and a forum app with push notifications and a dual-store release [Glossy Forum, with permission]

HOW I WORK
• Weekly working builds on TestFlight / Play internal testing, so you see the app, not a status report. • Clean architecture (BLoC/Riverpod), CI from day one, crash and analytics tooling before launch. • I lead and write the code personally; a TechSwivel designer or QA joins when a project needs it. You always know who is doing the work. • I build with Claude Code and Cursor, which is how I deliver a working build every week; every line is reviewed by a senior engineer before it ships.
