• Top Rated • React Native & Node.js • Apps in Production
I build mobile apps that handle real complexity: offline-first data sync, real-time WebSocket integrations, complex authentication flows, payment systems, and AI-powered features. On the backend I work with Supabase (Postgres, Auth, Edge Functions) and Node.js/Express when a custom API is needed. I also work with MongoDB for document-oriented projects. When the project needs web, I deliver with React, Next.js (App Router), and the same quality bar.
Shipped and running:
- Social marketplace app: 5-year engagement, real-time chat, bidding system, Google/Apple OAuth, Twilio SMS (React Native + Parse/MongoDB)
- EV fleet management: cross-platform mobile + web, API optimization from 5-8s → < 1s, CI/CD from scratch, test coverage 30% → 98% (React Native)
- Expense tracker: offline-first SQLite sync, AI receipt scanning (Gemini), Stripe payments, multi-currency settlement engine — live on Play Store and as PWA (React Native + Expo + Node.js)
- DEX arbitrage dashboard: real-time WebSocket price feeds, Uniswap/SushiSwap, candlestick charts (React Native + ethers.js)
- Client portal SaaS: multi-tenant, role-based access, real-time messaging, file sharing, i18n, dark mode (Next.js + Supabase)
Mechatronics engineering background — I think in systems, not just screens. Startup experience at Luna DNA (genomics/healthcare) and Nuvve (EV fleet management). 6+ apps on Play Store.
100% Job Success comes from asking the right questions before writing a single line of code. You handle the vision. I design, build, and ship the system behind it.
