## Headline

Backend Developer \| Python · FastAPI · PostgreSQL \| REST APIs & JWT Auth Systems

## About

I graduated with an MCA \(8\.3 CGPA\) and immediately asked myself: how do I build backend systems that actually hold up in production? That question led me to FastAPI, PostgreSQL, and a 3\-month internship at ENEGMA \(Tangerine Ventures\) — where I stopped writing tutorial code and started shipping real APIs\. In that role, I: → Built 15\+ production REST APIs handling authentication, data operations, and business logic → Designed an auth system using JWT \(access \+ refresh tokens\), Google OAuth 2\.0, and Email OTP — serving 100\+ daily active users → Optimized PostgreSQL queries and cut execution time by 60% → Built a full RBAC \(role\-based access control\) system from scratch → Designed 10\+ normalized database tables and custom middleware for request validation Before that, I completed a cybersecurity project at college — building a ransomware detection system using RanGAN and hash concealment — which gave me a deep appreciation for writing code that prioritizes security, not just functionality\. What I care about most: clean API design, security\-first thinking, and code that the next developer can actually read\. Tech I work with daily: Python · FastAPI · PostgreSQL · SQLAlchemy · JWT · OAuth 2\.0 · Git · Nginx · REST APIs Based in Villupuram, Tamil Nadu\.
