What I'm looking for

I'm open to remote opportunities in India or globally where I can lead architecture and Agile teams while building scalable SaaS, web, and hybrid-mobile products.

I'm leading architecture and full-stack development for Zillit at HKK Entertainment, an enterprise SaaS platform for the global entertainment industry across web, Android, and iOS. I built a reusable React/Next.js component library that reduced feature-development effort by an estimated 20–25% and improved performance by an estimated 30–40%.

Across R Systems, Shivkaal Infotech, STPL, and Singsys, I've delivered banking, e-commerce, facility-management, and marketplace products using React, Node.js, TypeScript, PHP/Laravel, AWS, REST, and GraphQL. I lead Agile delivery, architecture, code reviews, and mentoring for engineering teams while building secure, real-time, scalable systems.
