👋 Hi, I'm Nesan Selvan

🚀 Software Engineer @ NutriScan • Flutter & Dart • Python • Vision + LLM pipelines • Rust/Tauri on the side Mumbai, India.


🌟 About Me

I build AI products end to end: the model pipeline, the backend, the app, and the infrastructure under them. Most of my time goes to making models behave in production, where a wrong answer is a user's dinner.

Currently working on:

  • 🍽️  NutriScan: point a camera at your food, get the nutrition back
  • 🖥️  DevCLI: a terminal built for the Claude Code era
  • 📦  Flutter packages on pub.dev
  • 🦀  Learning Rust, mostly by writing desktop apps in Tauri
