Flutter & iOS developer with 7+ years shipping mobile apps across AI, fintech, social, and insurance — from solo MVP builds to production apps handling real user data. ⭐ 100% Job Success Score on Upwork · 25+ five-star reviews If you're starting a Flutter app from scratch, I take it from idea to the App Store and Play Store. If your app has an AI feature that needs to actually work — not just look good in a demo — that's usually where I come in. If a previous developer left you with something that needs an honest audit, I've been brought in for exactly that too. 𝗪𝗵𝗮𝘁 𝘆𝗼𝘂 𝗴𝗲𝘁 ✔️ One Flutter codebase shipped to iOS and Android at once — 80% faster than building two native apps separately. ✔️ Real AI integration: Claude/OpenAI API, prompt engineering, LLM fine-tuning — not a demo wrapper. ✔️ 4+ years of native iOS (Swift/SwiftUI) depth underneath the Flutter work, so I catch platform-specific issues Flutter-only developers tend to miss. ✔️ Hired specifically to audit and rebuild apps other developers left broken — 15+ rescue projects completed. ✔️ Apps shipped across AI, fintech, social, and insurance — there's a good chance I've already solved a version of your problem. Send me what you're building and I'll reply with a scope estimate and the first technical decision I'd settle. 𝗥𝗲𝗮𝗱𝘆 𝘄𝗵𝗲𝗻 𝘆𝗼𝘂 𝗮𝗿𝗲 👉 Click Message or Hire above to get started.
