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.

Work experience

Software Development Intern at ENEGMA (Tangerine Ventures Pvt. Ltd.), Nov 2025 - Feb 2026 · 4 mos, Shipped 15+ production-grade REST APIs in Python/FastAPI, covering auth flows, CRUD operations, and business logic — deployed to serve 100+ daily active users within 3 months. Diagnosed and rewrote slow PostgreSQL queries, reducing average execution time by 60% — improving response times across all data-heavy endpoints. Architected a custom RBAC system supporting multiple user types with granular permission control — eliminating unauthorized access edge cases found during security review. Implemented Google OAuth 2.0 and Email OTP login flows, reducing account creation friction and adding social login in under 2 days of development time. Built custom request validation middleware that blocked malformed inputs at the API gateway layer — improving overall API reliability and reducing error noise in logs.
