At Hexadecimal Software Pvt Ltd, I owned frontend development for a cross-platform SaaS product and delivered user-facing features end to end with React, Next.js, and TypeScript. I also built Node.js APIs and implemented real-time chat and notifications.

I implemented the product’s subscription and recurring billing system, enabling monetization, and improved API response times by 20% through query and data-flow optimization. After being promoted to Team Lead, I led sprint planning, task allocation, and code reviews, and mentored junior developers.
