Profile

Engineering Mindset

I am a Full Stack Engineer based in Jaipur, India, focused on building scalable SaaS products from idea to production. My work combines product thinking, strong engineering fundamentals, and execution speed using Next.js, React, TypeScript, and modern cloud tooling.

I design systems with clear architecture and secure foundations, then ship features that drive user adoption and business value. I work across frontend, backend, database, auth, payments, and deployment with an AI-systems mindset for long-term product leverage.
