About Me

Building Systems That
Scale & Deliver

I'm a Solution Architect and Full-Stack Engineer based in Gurugram, India with 15+ years of experience designing and delivering cloud-native, high-performance backend systems.

I've led engineering teams at startups and enterprise organizations, working with clients across government, financial services, telecom, and e-commerce. My background spans hands-on coding to stakeholder management and pre-sales RFP proposals.

With a freelancer mindset, I bring ownership, clear communication, and reliability. I don't just write code — I solve problems and deliver measurable results.
