Need a mobile product built end to end - app, backend, web, auth, real-time, shipped to the stores? That's what I do. React Native, Flutter, Supabase, Node.js.
I've spent 11+ years building mobile products, and I've contributed to products at Q.ai (acquired by Apple), Arpalus (acquired by Instacart), Resonai, Polarsteps, Evooia, ShotSense Golf, Clopinz Golf, Polarsteps, Crunchyroll, and more.
Today my focus is full-stack product delivery: I build the app, the backend behind it, and the pipeline that gets it live - without you having to hand off between three different contractors.

🚀 𝙒𝙝𝙖𝙩 𝙄 𝘽𝙪𝙞𝙡𝙙
🔹 Cross-platform mobile apps in React Native (Expo and bare) and Flutter
🔹 Supabase backends - Postgres schema design, Row Level Security, Auth, Storage, Realtime, Edge Functions
🔹 Node.js / NestJS APIs, webhooks, background jobs, third-party integrations
🔹 MVPs from zero to App Store / Play Store
🔹 Rescue work on stalled, inherited, or half-finished codebases
🔹 Native-to-React-Native migrations (and the reverse, when that's the right call)
🔹 Offline-first sync, push notifications, in-app purchases, Stripe billing
🔹 CI/CD with EAS, Fastlane, GitHub Actions

🗄️ Backend & Data:
Supabase, PostgreSQL, Node.js, NestJS, Express, REST, GraphQL, Prisma/Drizzle, Redis, WebSockets
⚙️ Infrastructure:
Docker, AWS, Vercel, EAS, Fastlane, GitHub Actions
🧩 Native (for when React Native isn't enough):
Swift, SwiftUI, UIKit, Kotlin, Jetpack Compose, custom native modules and bridges

Most React Native developers stop where the JavaScript stops. I don't. When a product needs the camera, sensors, on-device ML, AR, or 3D, I write the native module myself instead of hunting for an abandoned npm package.
That means I can also deliver:
🔹 Camera and real-time video processing pipelines
🔹 On-device AI/ML inference (Core ML, TensorFlow Lite, ONNX)
🔹 ARKit / ARCore features inside a React Native or Flutter app
🔹 LiDAR scanning, RoomPlan, 3D reconstruction, digital twins
🔹 Pose estimation, object detection, face and body tracking
🔹 Custom SDKs distributed to other teams (iOS, Android, React Native)
If any of that is on your roadmap, you've probably already discovered how few full-stack developers can actually ship it.
