Hello, I'm

Poovarasu Sekar

AI engineer and Associate Team Lead with 7+ years building production software. I've grown from full-stack into agentic AI — turning LLMs into dependable products (RAG, autonomous agents, on-prem LLMs, GenBI) — while leading and mentoring the Python teams that ship them.

About Me

I build software that's a joy to use — and AI you can actually trust.

I'm an Associate Team Lead and AI engineer with 7+ years at one company — six promotions from intern to lead. I started in PHP/Laravel full-stack, went deep in Python, Django and AWS, and today I focus on AI Engineering: production RAG systems, autonomous agents, and Generative BI. A Mechanical Engineering grad turned self-taught software engineer, I care about craftsmanship, clarity, and shipping AI that's measured, observable, and genuinely reliable.
