About

I’m a Software Development Engineer II at Coinbase, where I work as a full-stack developer to build seamless, reliable, and high-scale payment flows. Operating across the entire stack, my day-to-day ranges from architecting resilient backend microservices in Golang to crafting highly responsive, native mobile experiences in React Native. From leading end-to-end vendor integrations like Stripe to driving major performance migrations, my focus is always on scaling systems that serve a massive global user base. Before this, I interned at Sprinklr twice, where I built foundational systems like a client-side GraphQL query validator and streamlined onboarding for social influencers. Beyond my day-to-day work, I’m deeply into competitive programming—Candidate Master on Codeforces, 5★ on CodeChef, and Guardian on LeetCode. This background fuels my love for algorithmic problem-solving and writing highly optimized code. I also love channeling this end-to-end builder mindset into exploring tech entrepreneurship and developing early-stage products from the ground up. I'm always excited by high-impact engineering, bridging the gap between clean UI/UX and robust backend architecture, and scaling systems that just work. Let’s connect!
