About
I’m André, a Lead & Senior Flutter (Dart) mobile engineer with 7+ years of hands-on experience building cross-platform apps from clean architecture all the way to App Store and production release. I’ve logged 12,000+ Upwork hours and have led enterprise-grade mobile development for organizations like the PGA of America, delivering scalable apps used by thousands of golf professionals and millions of consumers.
I love turning complex product ideas into reliable, high-performance mobile experiences—whether that’s coaching and scheduling workflows, consumer experiences like handicap tracking and coach discovery, or optimizing UI rendering and state management with Flutter. I also enjoy integrating AI/LLM capabilities into real mobile workflows and building supporting backend services with Firebase/Supabase, using strong CI/CD and engineering practices to ship features on tight timelines.
