Overview

I build production-grade mobile and web applications that people actually use. From cross-platform mobile apps in Flutter and React Native to full-stack web platforms in TypeScript, I deliver clean, maintainable code with a focus on performance and user experience. My work on TOFY Go! - an English learning app handling 500K+ concurrent users - demonstrates this at scale.

What I Can Do For You

Mobile Applications

  • Cross-platform apps with Flutter (Dart) or React Native (TypeScript): one codebase, native performance on iOS and Android
  • Native integrations: Camera, GPS, push notifications, biometrics, speech recognition, and offline storage
  • App lifecycle: From App Store / Play Store submission to ongoing maintenance and feature updates
  • Real-world example: TOFY Go! - gamified English learning app for Bee2 AI, built with TypeScript, serving 500K+ users on AWS

Web Applications

  • SPA and SSR: React / Next.js for dynamic single-page apps, Hugo for blazing-fast static sites
  • RESTful and GraphQL APIs: TypeScript backends with Express, Fastify, or NestJS
  • Real-time features: WebSocket-based live updates, collaborative editing, push notifications
  • Responsive design: Mobile-first approach that works on every screen size

How I Work

  1. Discovery: Requirements gathering, wireframing, tech stack selection
  2. Development: Agile sprints with CI/CD and automated testing
  3. Delivery: Cloud deployment, monitoring, and ongoing support
