I build mobile applications that don’t just look good, they work reliably in real business environments. I’m a Flutter Mobile Engineer with 2+ years of experience developing production-style apps for startups, internal tools, and real-world use cases. My focus is on building scalable, maintainable applications that integrate cleanly with backend systems and can grow with the product. I’ve built solutions such as: • Rezysync - a residential management system with role-based access (admin, resident, security), real-time data handling, and modular architecture using Flutter + Supabase • An e-commerce mobile application • A real-time chat system inspired by modern messaging workflows • A Dart CLI package published on pub.dev to automate test generation for developers • Ongoing work on an AI-powered skincare platform Beyond development, I also train aspiring developers in mobile engineering, teaching them how to move from theory to building practical applications. I enjoy working with teams that care about shipping useful products, solving real problems, and building software that lasts. Tech Focus: Flutter, Dart, REST APIs, Django, Supabase, Firebase Open to: Remote roles, freelance projects, and product-driven collaborations.
