I’m an AI Engineer focused on turning unstructured enterprise data into fast, reliable AI insights. At Thoughtswin Systems, I engineered core features for Amplifi, an in-house document intelligence platform designed for actionable results from enterprise documents.

I deployed ML pipelines for ONGC & IOCL handling 1 Lac+ documents/day. I also improved OCR + semantic extraction accuracy by 95% and reduced latency to 500ms for real-time conversational AI in Indic languages.

Before that, I built product-grade mobile systems as a Core Mobile Developer (Backend & Frontend) on a contractual role. I architected both the React Native frontend and the Node.js backend, designed robust RESTful APIs for listings and booking transactions, and optimized performance and state management across iOS and Android.

I bring an applied ML mindset through projects like DotPay, where I built an offline emergency payment system for BHIM UPI. Using a Machine Learning outage predictor plus mesh networking with SMS fallback, I helped estimate payment access for 74.2% of users in internet-restricted areas, and I added a distributed validation layer with anomaly detection to preserve transaction integrity.
