SOFTWARE ENGINEER. CURIOUS HUMAN.

Quiet mind.
Loud code.

Hey, I’m Praveen Rajamani. [ prəˈviːn ]

I turn complex problems into systems that work.
Building with GenAI, Voice AI, multi-agent systems
and a full-stack engineer’s mindset.

01 / SELECTED WORK

Less talk.
More shipped.

A few things I’ve put out into the world.
Personal experiments and products built with a team.

IDEAS → REALITY
NO PERFECT SIDE PROJECT. JUST THE NEXT ITERATION.↳ ALWAYS BUILDING
02 / BEHIND THE KEYBOARD

More of a builder.
Less of a talker.

I’m Praveen, a software engineer based in Tiruvannamalai, India. I like making complicated things feel simple.

Over 5+ years, I’ve built production-grade enterprise AI applications, cloud-native backends, and full-stack products across EdTech, FinTech, IoT, and Web3.

My work lives where intelligent agents meet real-world systems: reliable orchestration, practical RAG, and voice pipelines that can keep up with a conversation. I’ve also led a team of 7 engineers from the first idea to production.
