I build Flutter apps and AI-powered web platforms that people actually use, not projects that collect dust after launch. I've shipped multiple production apps (HeyInterests, Alumni, IJS Vault), all with mobile + web versions, all with AI features baked in. Real apps. Real users. Not tutorials. My core: Cross-platform mobile apps with Flutter. One codebase, iOS + Android. I also build: Web apps (React/Next.js), AI-powered features (OpenAI, custom LLMs), and the backend to support it all (Supabase, Firebase, Node.js). My process: 1. We talk about what you need 2. I scope it properly so there are no surprises 3. Weekly updates so you're never in the dark 4. I deliver tested, working code, not half-finished projects I respond fast, I don't vanish mid-project, and I actually finish what I start. Got an app idea? Message me what you're building and I'll tell you honestly if I can help.

Hi there! I'm a seasoned Flutter developer with 6+ years of experience building high-performance, cross-platform apps using Flutter, Firebase, Supabase, and Dart. I previously served as CTO at Rentop Co, one of the UAEโ€™s top car rental platforms, where I led the development of the full systemโ€”from scalable web apps to interactive dashboards and mobile experiences. Currently, I work with a Japanese game studio on large-scale retail projects, and recently spoke at a Google Community Event in Tokyo about game development using Flame Engine.
