🚀My Journey
My path to software development wasn't conventional — and that's what makes it special. I started with a B.Tech in Civil Engineering from Mumbai University, where I learned to solve complex problems and think systematically. But during my time in the field, I discovered something unexpected: a deep fascination with technology and the power of code to create meaningful solutions.
In 2021, I made a bold decision to follow my passion and transition into software engineering. I enrolled in Masai School's intensive Full Stack Web Development program, where I immersed myself in JavaScript, React, and modern web technologies. Those months of rigorous training transformed not just my skills, but my entire career trajectory as a software developer.
Today, as a Frontend Developer and Software Engineer at CometChat, I build products that connect millions of users worldwide. From creating the Visual Chat Builder from scratch to developing AI-powered chat features, I've had the opportunity to work on cutting-edge technology that makes a real impact. My engineering background gives me a unique perspective — I approach frontend development with the same precision and problem-solving mindset that civil engineering demands.
This journey taught me that it's never too late to pursue what truly excites you. Every line of code I write as a software engineer is a reminder of that leap of faith I took, and I'm grateful for where it's led me.
