Principal Engineer crafting planet-scale distributed payment and AI/LLM systems.
IndiaWhat I'm looking for
I’m an engineering leader with 13+ years of cross-industry experience building planet-scale systems across Payments (B2B SaaS), e-commerce, OTT video streaming, and ride mobility. As a Principal Engineer, I’ve managed teams exceeding 50+ engineers and focused on the design of planet-scale, high-throughput distributed systems with scalability, reliability, and extensibility.
At Razorpay, I built Brahma—an internal agentic SDLC tool that automates the end-to-end development lifecycle, helping modernization efforts cut migration time by ~65%. I also architected LLM-based fraud prevention and delivered major reliability and performance wins, including 150+ architectural defects fixed across 15+ core payment services, plus 10x latency reduction in payment routing.
