Senior Software Engineer at Microsoft with 8+ years of experience building React Native and Flutter mobile apps. 5x world record holder in tech, including a Guinness World Record. 2025 Misk Global AI and Tech Award winner. On the Teams platform at Microsoft 300 million daily users. Most react and flutter mobile apps fail because of bad engineering, not bad ideas. I build React Native and Flutter apps for iOS and Android that are fast, maintainable, and built to scale and where it actually adds value, I integrate AI and automation into the product instead of bolting it on as a gimmick. AI automation and AI-powered mobile apps are core to what I do, along with most things coding. You're not hiring a coder. You're hiring someone who takes ownership, ships on time, and leaves your team with code they can actually maintain. I've built healthcare platforms live in hospitals, enterprise software at Microsoft used by 300 million people a day, and production apps handling real payments and real data. I know what it takes to ship something that doesn't break when it matters. That's the difference between a freelancer and a partner. I'm the latter. Some of what I've built: ORRCA — a live healthcare platform running across 4 Vancouver hospitals, managing patient records and clinical workflows with real-time sync and HIPAA compliance. React Native, Supabase backend. Kinetix — an iOS/Android physiotherapy app for ACL rehab, with HealthKit integration, video-guided exercises, and offline support. Built in Flutter. PawMatch — a pet-sitting marketplace with swipe-based matching, real-time messaging, and Stripe-powered payments at marketplace scale. Flutter. Beauty Appointment App — a cross-platform booking app built in FlutterFlow, optimized for conversion, with real-time backend sync. Microsoft Teams — enterprise mobile app, 300 million daily users. I work across React Native, Flutter, Supabase, Firebase, Node.js, and AWS, and I build AI-powered features using OpenAI and ChatGPT integrations when they genuinely improve the product. I've also shipped BLE/IoT integrations, Stripe Connect marketplace payments, HealthKit/Health Connect, and full App Store and Play Store submissions. I've worked across healthcare, fintech, marketplaces, fitness, and enterprise SaaS — different industries, same standard: clean architecture, security done right from day one, and performance that holds up under real usage. How I work: NDA before anything sensitive gets discussed. Scope and milestones locked in writing before any code gets written. GitHub and Supabase access handed to you on day one you own everything from the start. I turn down projects that aren't the right fit, so the ones I take get my full attention, not a slice of it split across twenty clients. If you've got a spec, a timeline, and a real budget message me with your scope. I'll tell you within 24 hours if I'm the right fit, and if I say yes, you have my full commitment. Best, Rayyan Siddiqui
