I'm a Senior Software Developer with 5+ years of experience designing and operating backend systems at national scale. At Digital India Corporation, I build and maintain platforms that millions of Indians use daily β from document storage and academic credentialing to youth engagement and identity verification.
Outside my day job, I build civic-tech and AI-powered tools, focusing on problems that matter in the real world.
Currently working on:
- ποΈ UrbanLens β AI-powered urban infrastructure intelligence platform (in progress)
- πΎ KrishiDrishti β AI crop yield prediction for Northeast India (Phase 9 complete Β· Live)
- π‘ Data Processing Workers β High-volume RabbitMQ + S3 + Redshift pipelines
AI-powered crop yield intelligence for Northeast India Β· β Complete Β· Live Demo Β· Repo
Predicts district-level agricultural yields across 95 districts and 8 Northeast Indian states using ML models trained on real satellite, weather, and soil data.
Highlights:
- π€ XGBoost + LSTM models for 5 crops (Rice, Jute, Wheat, Mustard, Maize) β trained on 12,350 yield records
- π°οΈ Real data pipelines β Open-Meteo weather API, MODIS/GEE satellite NDVI, ERA5 soil moisture
- πΊοΈ Interactive choropleth map β state/crop/year filters with click-to-explore districts
- π Explainable AI β SHAP feature importance on every prediction with confidence intervals
- π Security hardened β CSP headers, rate limiting, input validation, CORS, error boundaries (Audit: B+)
- π³ Deployed on Oracle Cloud (Mumbai) via Docker Compose + Nginx

AI-powered urban infrastructure intelligence platform Β· β Complete Β· Live Demo Β· Repo
Analysing urban infrastructure patterns, public amenity gaps, and city-level planning indicators using geospatial data and ML.
Features:
- Real-time congestion prediction β XGBoost and LSTM models predict segment-level congestion scores for the next 15 / 30 / 60 minutes
- Multi-factor feature engineering β time-of-day, day-of-week, weather conditions, public holidays, and nearby event calendars
- Java API Gateway β Spring Boot 3 handles auth, rate limiting, caching, and proxying to the ML engine
- JWT authentication β Spring Security with role-based access (
ADMIN,ANALYST,VIEWER) - Smart caching β Redis TTL-based prediction cache reduces ML calls by ~70 %
- Custom FastAPI docs β branded Swagger UI with dark terminal theme and interactive playground
- Interactive dashboard β Next.js heatmap, segment drill-down, and historical trend charts
- Dockerized deployment β single
docker compose upspins the full stack on Oracle Cloud free tier
