What I Bring
REST APIs built to last — JWT/RBAC auth, rate limiting, task queues, full test coverage, and clean API contracts. Owned delivery of 50+ endpoints across e-governance platforms serving 5+ Indian states.
Schema design, multi-table JOINs, CTEs, window functions, stored procedures, and execution plan tuning on 1M+ record datasets. Delivered 35% query speed improvement on a live government platform.
Designed and delivered complete per-tenant data isolation across 20+ municipalities — JWT + RBAC across 6 roles and 20+ endpoints with zero privilege escalation recorded in production lifetime.
WebSocket-powered live dashboards, notifications, and collaborative tools with Django Channels and Redis pub/sub. Celery beat for background jobs, periodic tasks, and async pipelines.
Containerized deployments with Docker Compose, CI/CD via GitHub Actions, and cloud setup across AWS (EC2, S3, RDS), Railway, and Supabase. Cloudflare DNS, SSL/TLS, and full production security hardening.
Plug AI into existing backends — GPT and Gemini-powered features, smart automation, and AI chat interfaces. End-to-end delivery from database schema to React frontend, deployed and maintained.
