I have been coding since 2011, amassing extensive experience in software and web development, as well as machine learning engineering. Currently, I am pursuing a Master’s degree at Queen’s University in Canada, focusing on AI, NLP, and LLM applications in the legal field. My professional background includes roles as a full-time employee and part-time contractor in software development, web development, big data engineering, and machine learning engineering.

WHO I AM 7+ years of production mobile development. 5x world record holder in tech, including a Guinness World Record. 2025 Misk Global Tech Award winner. Senior Software Engineer at Microsoft on the Teams platform 300 million daily users by day. Most mobile apps fail not because of bad ideas, but bad engineering. I build iOS and Android apps that are fast, maintainable, and built to scale whether you're launching your first MVP or fixing what a previous team left behind. THE PROBLEM I SOLVE I ship products that scale. You are not hiring a coder, you are hiring someone who will take ownership, deliver on time, and leave you with code your team can actually maintain. I have built healthcare systems for hospitals, enterprise apps at Microsoft used by 300 million daily users, and production apps that handle real payment flows and real data. I know what it takes to ship software that does not break when it matters. That is the difference between a freelancer and a partner. I am the latter. SELECTED WORK ORRCA, live healthcare platform across 4 Vancouver hospitals. Manages patient records, clinical workflows, and real-time data sync with HIPAA compliance. Built with React Native and a secure Supabase backend. Kinetix, iOS and Android physiotherapy app for ACL injury rehabilitation. HealthKit integration, video-guided exercises, offline functionality, and progress tracking. Built with Flutter. PawMatch, pet services marketplace connecting sitters with pet owners. Swipe-based matching, real-time messaging, Stripe payment processing. Flutter and marketplace architecture at scale. Beauty Appointment App, progressive web app for beauty appointment booking. Cross-platform mobile and web, optimized for conversion. FlutterFlow with real-time backend sync. Microsoft Teams, enterprise mobile app, 300 million daily users. WHAT I BUILD React Native and Flutter apps for iOS and Android Cross-platform mobile app development and MVP delivery Gamification systems — XP engines, streaks, quests, leaderboards BLE hardware and IoT device integrations Stripe Connect with marketplace payments, subscriptions and split payouts Supabase and Firebase backends with row-level security AI and ChatGPT feature integrations HealthKit and Health Connect integrations Full App Store and Google Play submission and compliance Admin dashboards and web applications Node.js backend and REST API development TECH STACK Mobile: React Native, Flutter, Expo, iOS, Android Backend: Supabase, Firebase, Node.js, REST API, AWS Payments: Stripe Connect, in-app purchases, subscriptions AI: OpenAI, ChatGPT integration, AI-powered mobile apps Health: HealthKit, Health Connect, BLE devices INDUSTRIES I HAVE BUILT FOR Healthcare and medical platforms Enterprise software and SaaS Consumer health and wearables Fintech and payments Marketplace and two-sided platforms Community and social platforms Fitness and wellness apps Education and e-learning WHY I AM DIFFERENT Ownership Mentality. I do not just write code, I care about your success. Your problem becomes my problem. I will not ship something unless I would be comfortable using it myself. Clarity and Predictability. NDA before sensitive discussion. Scope and milestones locked before any code. Weekly check-ins. GitHub and Supabase access on Day 1. You own everything from the start. No surprises. Selective Not Desperate. I turn down projects that are not the right fit. This means you get my full focus, not a divided contractor juggling 20 clients. Enterprise Standards at Freelance Speed. Microsoft-quality code. Clean architecture. Security baked in. Performance optimized from Day 1. WHO I WORK BEST WITH Funded startups, growing companies, and enterprises who need a senior mobile app developer, not a code monkey. If you have a spec, a timeline, and a real budget, we will work well together. HOW WE WORK TOGETHER Step 1. Message me with your scope. I will respond within 24 hours and tell you if I am the right fit. Step 2. Alignment call. We discuss your product, timeline, and expectations. No surprises. Step 3. Scope locked. Milestones, deliverables, and timeline in writing before any code. Step 4. Day 1 ownership. GitHub, Supabase, and all credentials transferred to you. You own the code from the start. Step 5. Weekly check-ins. Video sync to keep you updated. No ghosting, no excuses. If your project is serious, message me with your scope. I will tell you within 24 hours if I am the right fit. If I say yes, you have my full commitment. Best Rayyan Siddiqui
