I help funded SaaS startups ship production-grade Flutter apps for iOS and Android — and I don't disappear after launch. Top Rated Plus, 100% Job Success, 3,800+ hours on Upwork, 50+ apps and platforms delivered for founders in the US, UK, UAE, Canada, and Europe.
Most clients come to me for one of three reasons: an MVP that needs to get built fast and correctly the first time, an existing Flutter app that's turned into a mess nobody wants to touch, or senior judgment they can trust without micromanaging. I've shipped all three, repeatedly.
★ Recent work
→ RYSY: AI facial-analysis app using GPT-4 Vision to score selfies and predict how meals affect skin. Built from scratch and shipped to both stores (★5.0: "a lot of experience in the field — I can only recommend")
→ Bammbuu: language-learning marketplace with live 1-on-1 video classes, an AI tutor, real-time chat, and subscription billing. Two-sided, iOS + Android
→ Sofina AI: an AI video studio that turns text and images into short clips across multiple models (Veo, Kling, Seedance), with a credit economy and a creator feed
→ Kaprayy: a multi-brand shopping app aggregating 50+ fashion stores via a custom Shopify plugin that auto-syncs catalogs and routes orders back to each brand
→ RentMeBeach: a two-sided rental marketplace with live driver tracking over WebSockets, Stripe + Stripe Connect payouts, and QR delivery verification
★ What I build best
→ Flutter & Dart — clean architecture (BLoC / Riverpod) and custom UI that never looks templated
→ Firebase — Firestore, Auth, Cloud Functions, FCM push, Cloud Storage
→ Payments — Stripe subscriptions, in-app purchases (App Store + Google Play), Shopify
→ AI features — OpenAI / Gemini / Anthropic integrations and on-device ML that move the product forward, not demos
→ Real-time — live chat, video calls, GPS tracking, push notifications
→ Release — App Store Connect, TestFlight, Play Console, review-ready submissions
★ Who I'm the right fit for
→ Funded startups building v1 or scaling past MVP
→ Founders who want a senior developer, not a ticket-taker
→ Teams who value clear communication and code they can build on after I hand it over
If that sounds like your project, send me a quick note with what you're building and where it's stuck. I'll tell you honestly whether I'm the right person - and how I'd approach it.

Need a high-performance iOS and Android app without paying for two separate native teams? I build production-ready Flutter and FlutterFlow apps from a single codebase, so you ship to both stores faster, cheaper, and with one team instead of two.
As a Top Rated Plus mobile engineer with a 94% Job Success Score and over $200K+ earned on Upwork, I turn complex backend systems into fast, fluid mobile experiences. Whether you need a brand-new MVP from scratch, an AI-powered app, or a rescue mission for a buggy legacy codebase, I write clean, scalable, architecture-compliant code that's built to last.
📱 See the proof, not just promises:
I've shipped real, live apps you can download and test today, marketplaces, AI clinical tools, on-demand logistics, wellness, and education platforms. Check the portfolio section below on my profile to download them straight from the App Store and Google Play.
✅ Problems I solve for clients:
"My app idea needs to launch on iOS and Android fast" → one Flutter codebase, both platforms, half the cost.
"I have designs but no developer" → Figma-to-Flutter conversion into responsive, pixel-accurate UI.
"I need AI features in my app" → speech-to-text, LLM/ChatGPT APIs, and automated data workflows integrated cleanly.
"I need payments and subscriptions" → Stripe, in-app purchases, and billing systems done right.
"My existing app is slow or buggy" → performance tuning, refactoring, and bug rescue on legacy code.
"I need it on the stores" → full App Store and Play Store deployment and compliance handled end to end.
🛠️ Technical Stack:
Mobile: Flutter, FlutterFlow, Dart, Kotlin, Java
State Management: BLoC, Riverpod, Provider, Clean Architecture
AI Integrations: Speech-to-text, LLM/OpenAI APIs, automated summarization
Backend & Cloud: Firebase, Supabase, MySQL, REST APIs, SQLite, Azure DevOps CI/CD
Native: Geofencing, background services, push notifications, Stripe & in-app subscriptions
Design: Figma-to-Flutter, Material Design, responsive multi-device layouts
📈 How we'll work:
A short discovery call to map your architecture, a clear scope and timeline, clean code with regular check-ins, and a tested app deployed to both stores.
If this sounds like what you need, click "Invite to Job" at the top right, share your Figma files or requirements, and let's map out your build.
