AI app developer — I build AI image, video, and voice apps for iOS and Android (ChatGPT, OpenAI, Gemini, fal.ai), with the unit economics designed in from day one. Every feature in an AI app has a price tag — each image, video, or transcription is an API call you pay for — so I build apps where users pay for credits before your backend spends a cent on AI. Every API call is profitable instead of a cost you eat.
This isn't theory — it's how my shipped apps work:
- An AI image / video / music generator app (fal.ai, Gemini, ElevenLabs) — built solo and shipped in under a month on iOS and Android, with an atomic Firestore credit ledger, RevenueCat subscriptions + coin packs, and moderation gates so policy-violating requests still consume the credit.
- An AI celebrity image / video iOS app (Swift / SwiftUI, fal.ai + Gemini) — I own all post-handoff development: five shipped App Store releases, the credit/quota architecture, paywall, and Cloud Functions backend.
- An AI voice-notes app (OpenAI Whisper + GPT, Google AI) — primary author (~80% of the code), with a credit + in-app purchase system.
WHAT I BUILD INTO YOUR APP
- Monetization that protects your margin: in-app purchases via RevenueCat, StoreKit, and Google Play Billing — subscriptions with fixed daily credits (non-rollover), one-time credit packs, token quotas with hourly/daily/weekly resets, and paywalls that appear exactly when the balance runs out.
- Web credit top-ups via Stripe: a companion web app where users buy credits outside the app stores and spend them in your mobile app — lower fees, structured to stay store-compliant.
- AI integration done right: ChatGPT / OpenAI, Google Gemini, fal.ai, ElevenLabs, and whatever frontier model fits your product — with queue + webhook patterns so long-running jobs survive app restarts, and NSFW / content-moderation gates built in.
- Identity & analytics: Google and Apple SSO, email/password, and phone OTP, so every credit and event ties to a real user. PostHog instrumented across the funnel (install → signup → paywall → purchase → generation). Account deletion built in for store compliance.
- Store launch as a fixed milestone: I handle App Store and Play Store submission and review — the milestone is paid when your apps are live, not when I press "submit."
STACK & TRACK RECORD
Flutter / Dart (my primary stack for 5+ years; 7+ years in mobile), Firebase (Auth, Firestore, Storage, Cloud Functions v2 in TypeScript), and native Kotlin / Swift for the gaps Flutter can't reach — watchOS / Wear OS companion apps, platform channels, VoIP push. When Firebase isn't enough, I build the backend myself: Node / Express / PostgreSQL with Stripe hold-and-capture payments. Payment systems integrated across projects: RevenueCat, Stripe, SumUp, Mollie, Flutterwave.
~380,000 hand-written lines of code across 40+ solo projects, 11 shipped. Currently also contributing to GETTR, a public social app with a ~494k-line Flutter codebase — performance optimization, live-streaming features, and test automation.
If your AI app is bleeding API costs — or you want the next one built profitable from day one — send me a message with what you're building. I'll come back with a concrete plan: credit model, paywall placement, analytics events, and a fixed launch milestone.

I build Flutter apps that ship — not prototypes that stall at 80% done.
Over the past 4+ years I've taken 30+ mobile products from a blank repo to the App Store and Play Store, including AI-powered apps, FinTech tools, and real-time platforms used by paying customers today. If you need a developer who can own the full build — architecture, AI integration, backend, deployment — you're in the right profile.
What I actually solve for clients:
* You have an idea or a stalled project and need someone who can architect it correctly the first time, not patch it later
* You want AI features (OpenAI, Gemini, Claude, custom LLM workflows) built into a real product, not a demo
* You need Firebase set up properly — Auth, Firestore, Cloud Functions, FCM — so it scales past your first 1,000 users
* You want both Flutter and native iOS (SwiftUI) capability under one contractor instead of coordinating two teams
Recent work includes:
* AI-powered health and fitness apps with OpenAI-driven personalization
* Real-time chat and social apps built on Firebase + Socket io
* FinTech apps with secure payment gateway integration
* NFC-enabled apps for access control and card reading/writing
* Alarm and background-service apps requiring native platform depth beyond standard Flutter plugins
How I work:
* Clean Architecture, testable code, and documentation — so your next developer (or I, six months later) isn't guessing
* Direct, frequent communication — no disappearing between milestones
* I scope realistically upfront; I don't pad timelines to inflate hours, and I don't lowball to win the job then stall
Tech stack:
Flutter, Dart, FlutterFlow, SwiftUI, Firebase (Auth, Firestore, Cloud Functions, FCM), REST APIs, OpenAI/Gemini/Claude API integration, Provider, Riverpod, Bloc, GetX, Socket io, Google Maps, NFC, payment gateways.
If your project needs someone who can go from Figma file to App Store approval without handing off pieces to three other freelancers.
Send me a message with what you're building and I'll tell you honestly whether I'm the right fit.
