I engineersystems that turndata into intelligence..

I'm a Data and AI/ML Engineer from Trivandrum, India. I build data-driven systems and intelligent applications end to end — from data pipelines and analytics to LLM-powered tools and production software.

I taught myself to code through curiosity. Years later, that same curiosity drives the work: SQL alongside Python, data pipelines alongside AI agents, robust architecture alongside thoughtful interfaces, and experimentation alongside production engineering.

The work is usually quiet. The details are not.

(02) · CapabilitiesWhat I actually build with

A toolkit, not a stack.

A practical toolkit for turning raw data into reliable systems and intelligent applications — from data pipelines and analytics to LLM-powered workflows and AI tooling.

LLM Based Holographic Assistant

A conversational assistant embodied as a 3D avatar. An LLM handles the dialogue while a Unity front end renders the character in real time, so talking to it feels closer to a presence than a chatbot.
