What I Built

Suvidha AI — AI platform empowering 15M+ gig workers in India with earnings forecasting (LSTM), demand heatmaps, bias detection (Isolation Forest), and a Hindi-first AI assistant via AWS Bedrock. Built for the AI for Bharat Hackathon.

ET Sentinel — Multi-signal convergence engine cross-correlating fundamental, technical, and sentiment signals across Nifty 200 every 2 hours. Shortlisted from ~55,000 teams at ET Gen AI Hackathon. Stack: Next.js 14, Python Lambda, DynamoDB, Angel One SmartAPI, GDELT + VADER.

ITMS for Indian Railways — Integrated Track Monitoring System built at Smart India Hackathon 2025 (Finalist). Real-time IoT-based track condition monitoring with predictive analytics and full-stack dashboard.

EXPO PAY — Cross-border payment platform on the Stellar blockchain with Universal IDs, smart escrow contracts, and fiat-to-crypto conversion.


Research

Actively exploring diffusion-based language models (dLLMs) — LLaDA and Dream framework — evaluated on Hindi/Bengali. Working toward an arXiv preprint on dLLM performance on Indian languages (first-mover territory as of Feb 2026).

Building GigWork-India-Bias — a HuggingFace dataset for gig economy fairness research.
