About Me
A brief introduction
I am a Backend Integrations Engineer with 10+ years of experience specializing in Ruby on Rails and TypeScript. I excel at building robust APIs, designing third-party integration services, and architecting scalable backend systems. I have co-founded my own startup, built applications from scratch, and led development teams on product development.
I have been working remotely for past 6+ years. I live in India, but can overlap 4/5 hours with any time zone.
Currently, I'm actively looking for a remote contract (20/30/40 hours per week) or a full-time role with Ruby on Rails, TypeScript, or NestJS.

When I need to go from idea to working software fast, Ruby on Rails is still the framework I trust most — and after a decade, here's why.
Building a Remote Work Culture That Actually Holds
After more than six years working fully remote, I've learned that remote culture isn't about tools or perks — it comes down to discipline, trust, focus, and time management.
