Launch Your App & Keep It Running. Experienced Flutter Developer
Have an app idea or a Figma design, but worried the project will stall halfway, ship full of bugs, or fall apart after launch? That's the problem I solve. I take your concept from design to a live app on the App Store and Google Play, and I keep it stable after release. I use one Flutter codebase for iOS, Android, and web so you pay for one build instead of three. What you can expect when working with me: - An app that works after launch, not just on demo day. I focus on solid architecture, tests, and clean code your next developer can read. - Updates you don't have to chase. You'll always know what's done, what's next, and what's blocking progress. - Faster delivery without cutting corners. I use Claude Code every day to scaffold, refactor, test, and debug. Every architecture decision and code review stays with me so more of your budget goes to features and less to boilerplate. What I can add to your product: 💳 Monetization: Stripe, RevenueCat, in-app purchases, AdMob 🤖 AI features: voice, chat, and generation with Gemini, Grok, Deepgram, ElevenLabs 🗺 Location: Google Maps, GPS, geofencing, BLE beacons 🕶 Augmented reality: ARKit and ARCore through Flutter ☁️ Backend: Node.js/Express, Firebase (Auth, Firestore, Functions, FCM, Storage), REST APIs, OAuth 2.0 🌐 Web: Next.js, React, WordPress Since 2015 I've finished 190+ projects on Upwork for startups, agencies, and companies in the US, Italy, and Australia, and I've earned Top Rated Plus status. Many clients keep working with me long after the first release, because an app is never "done." There's always a next feature, a next OS update, or a next idea. Tell me about your project: what you're putting together and what's getting in the way. Even if I'm not the right fit, I'll say so up front and point you in a helpful direction.
