## About

I’ve always wanted to work on projects that create real impact and make people’s lives better\. Right now, I’m working with Leap 300, where we’re helping people overcome poverty and build better futures\. It feels great to see how tech can truly change lives when used with the right intent\. Before this, I was at Khatabook, where I got the chance to lead a product from the ground up — from an idea on paper to something used by over 1 lakh paid users\. That experience taught me how to take something from concept → design → development → and finally into users’ hands\. Most of my experience is in backend development, especially with Node\.js, and I enjoy solving system design and scaling challenges\. I love turning ideas into real, working products that actually help people\. Always open to working on something meaningful and learning from great teams\.
