Hi, I'm Suman.
Staff Software Engineer with 13+ years building cloud-native, distributed systems — scalable backends, RAG pipelines, and agentic AI that ships to production.
About
I'm a Staff Software Engineer with 13+ years building cloud-native, distributed enterprise systems — mostly in Python and Java. I work across microservices, RESTful APIs, CI/CD, and AWS/Kubernetes, with a recent focus on RAG pipelines and agentic AI for production financial platforms.
I care about systems that are scalable, reliable, and genuinely useful. Lately I'm building in public — and I write the occasional note on the blog.
