Senior software engineer specializing in scalable distributed systems and cloud-native solutions.
IndiaWhat I'm looking for
I am a senior software engineer with a strong track record building large-scale, cost-efficient distributed systems and subscription platforms across global marketplaces. At Amazon I designed and shipped high-throughput savings and ingestion engines processing billions of shipments and hundreds of millions of subscriptions while substantially reducing infrastructure costs.
I lead and mentor engineers, enforce operational excellence, and drive cross-functional projects—from an AI-powered Interview Co‑pilot using AWS AI services to resilient payment and auto-debit systems that improved conversion metrics. I prioritize observability, automation, and customer-centric design in every delivery.
My background includes full-stack and cloud-native experience, strong system design and performance optimization skills, and a history of measurable impact in production systems. I seek roles where I can architect scalable services, mentor teams, and deliver measurable business outcomes.
