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.
