Software Engineer with 7+ years of experience building scalable, distributed systems. Currently SDE 2 at Amazon Ads, leading end-to-end development of full-stack features spanning backend services, APIs, React frontends, and cloud infrastructure on AWS.

I hold a Master of Science in Machine Learning from Carnegie Mellon University (2020) and a B.Tech in Computer Science from IIT Kharagpur (2017).

At Amazon Ads, I own large-scale systems including an advertiser permission delegation platform, batch access control APIs, micro-frontend KPI widgets, and observability pipelines — contributing across ~18 packages from backend to CDK infrastructure.

Beyond my day job, I’ve built AI-powered products: a vector search recommendation engine at Zaytun AI, a Generative AI workflow automation system at HyperWater.ai, and a RAG-based medical AI platform as CTO of CeraMD.ai.
