Hi. I help founders and businesses turn app ideas into real mobile products for Android and iOS. 🤖 I can take ownership of the full technical path: architecture, Android or Flutter, backend integration, Firebase, Supabase, testing, debugging, and release preparation. I use AI tools in my daily workflow to move faster, while I stay responsible for code quality, edge cases, and final delivery. 🚀 Launch your MVP in 2–4 weeks. If you're a startup with an idea, I'll help you scope it down to what actually matters and ship something real — not a prototype that falls apart under pressure. 📱 Build for Android & iOS. Flutter for cross-platform apps with one codebase. Native Kotlin when you need deep Android integration. I can work from your Figma or create wireframes myself using tools like Stitch. 🔄 Bring your iOS app to Android. Already have an iOS app? I build the Android version without reinventing the wheel on design and logic. ⚙️ Add a backend. Java/Spring for custom logic that needs to scale. Firebase or Supabase for faster setup. Either way, it won't cause you headaches later. 🛠️ Fix what's broken — or audit before it breaks. App crashing? I find root causes, not just symptoms. Not sure what state your project is in? I can do a technical audit and give you an honest picture. ⚡ Revive abandoned projects. Half-finished app left by a previous developer? I'm used to picking up messy codebases and turning them into something shippable. 🏆 I've been building mobile apps since 2011 — one of the earliest Android developers, with experience across early-stage startups and enterprise teams. I think about how the decisions I make today will affect your project six months from now. If something looks like a risk, I'll flag it before it becomes your problem. Most of the past 5 years I worked full-time (including a 5-year backend role at a SCA startup). I'm now back on Upwork full-time with 100% Job Success Score. ✍️ If any of this sounds like what you need — just send me a message.
