About

I build things end-to-end — data pipelines, ML systems, AI products, and occasionally entire virtual operating systems on Android. Currently a Data Engineer I at ExxonMobil, where I own the full lifecycle of high-visibility dashboards used by senior leadership — from PySpark pipelines on Databricks to Spotfire visualisations that drive real decisions. Before that, I led enterprise AI pilots at Cuebo.ai for brands like Chaayos, Wakefit, and Spinny — sitting at the intersection of prompt engineering, full-stack development, and client ownership simultaneously. And before that, I spent 9 months at Samsung R&D building a Virtual Secure OS on Android from source — compiling ~155K build targets, integrating OP-TEE, and passing 26,182 regression tests with zero failures. In between all of that, I co-authored a peer-reviewed paper published in Frontiers in Medicine (IF ~3) on a demographic-aware ML framework for liver disease prediction. Outside tech, I've grown a 50K+ Instagram audience from zero, secured brand deals with Amazon Prime Video, managed social media for Lucknow Super Giants during the Cricket World Cup, and ran a profitable Shopify store — all while in college. I like hard problems, fast environments, and full ownership.

design, iteration, client communication, and problem resolution for each pilot from start to finish.
On the technical side, my primary contribution was designing and iterating complex AI prompt engineering pipelines to build accurate customer personas and power automated, personalised
sales interactions. Also built and shipped full-stack product features (Django + React + TypeScript) and contributed to analytics work tracking product-driven growth.

Exxonmobil

Data Analyst

May 2024 – Jul 2024 · 2 mos · Bengaluru, Karnataka, India · On-site

Summer internship at ExxonMobil, Bengaluru. Built the LERN dashboard — a real-time analytics

This internship directly led to a full-time offer as Data Engineer I.
