Who I Am

I'm a solution-driven backend engineer with 10+ years of experience building scalable, high-performance systems. I specialize in Golang microservices, distributed systems, API design, and cloud-native infrastructure.

My career spans security, automotive, e-commerce, and SaaS — from handling 1M+ API calls/day at Toyota to building payment platforms at Fitpass. I thrive at the intersection of engineering excellence and business impact.

Academically, I secured an under-500 AIEEE state rank in Uttarakhand, scored 93% in 10th (ICSE), 90% in 12th (ISC), and 80% in B.Tech. I'm also a State-Level Table Tennis Silver Medalist and recipient of multiple company awards including "Emerging Star" and "Pillar of Success."
