$ About
I'm a backend developer who cares about services that stay fast under load and correct when things go wrong. I've built URL shorteners, single sign-on auth, multi-tenant task backends, and S3 file pipelines, working in Python (FastAPI, Django) and Node.js (Express, TypeScript) on PostgreSQL, Redis and AWS.
I'm studying Computer Science at SR Group of Institutions, Jhansi, and apply that grounding in distributed systems and databases directly in my projects. Bring me a product that needs a solid backend and I'll build the service for it.
Projects
Production-style services, each with its code on GitHub.
A low-latency URL shortening service on Node.js and Redis with strict input validation, permanent redirects, and protection against cache stampedes under high-throughput traffic.
A secure snippet sharing platform built with FastAPI and PostgreSQL, featuring cursor-based pagination and automatic expiry through TTL indexes and scheduled background cleanup.
An SSO-capable authentication microservice in Django with bcrypt hashing, granular permissions, JWT service-to-service auth, HTTP-only cookies, and strict refresh-token rotation.
A multi-tenant task backend with ACID transactions, complex relational modeling, and dynamic filtering, sorting, and keyset pagination.
A FastAPI file service that streams large multipart uploads and downloads straight to AWS S3, with metadata tracking and Celery jobs for media compression.
