I started in Electrical Engineering. Somewhere along the way, I got obsessed with backend systems — distributed task queues, async APIs, CI/CD pipelines — and never looked back.

I've built and shipped production-grade projects using Python, FastAPI, Django, Celery, Redis, and Docker, with real deployments on AWS and Render. My engineering background makes me think in systems, not just features.

I don't just write code — I build it, ship it, and own it end-to-end.

• Built a distributed task queue using Celery + Redis + FastAPI with priority-based routing (high / default / low), concurrent execution, and exponential backoff retry logic
• Developed a real-time monitoring dashboard with WebSocket-driven live stats, Chart.js throughput visualization, and a Celery worker inspector with active/reserved/scheduled task tables and one-click task revocation
• Containerized the full stack using Docker Compose (6 services) locally and on Render cloud; integrated Upstash Redis (TLS/SSL) as managed broker and result backend

A production-grade marketplace REST API built on FastAPI with a React 18 frontend.

• API & Auth: FastAPI (Python 3.12) + SQLAlchemy 2.x with JWT access/refresh token rotation, RBAC, and SELECT FOR UPDATE concurrency control preventing checkout race conditions
• Payments & Async: Razorpay integration with HMAC-SHA256 webhook verification and idempotency handling; Celery + Redis async task queue delivering order confirmations via Resend API in <50ms
• Search & Storage: Elasticsearch full-text product search with relevance scoring; AWS S3 (ap-south-1) for Pillow-optimized image storage
• Data Layer: PostgreSQL with Alembic migrations and composite indexes; Redis for cart (atomic HINCRBY), API caching (TTL invalidation), and rate limiting
• Frontend & DevOps: React 18 + TypeScript + Zustand + React Query; 5-service Docker Compose setup; GitHub Actions CI/CD with 105 pytest-asyncio tests at >80% coverage
