About
About
B.Tech (CSE) graduate and backend-focused full-stack developer with freelance experience since 2023 building production systems — ledger/fintech backends, real-time trading automation, and MERN/Angular web apps. Strong in REST API design, authentication & security (JWT, Bcrypt, OAuth2), and MongoDB data modeling.
Built a banking ledger system with double-entry accounting and idempotency protection, developed a real-time Telegram signal bot for NIFTY and XAUUSD with sub-second latency, and created full-stack social feed applications with Cloudinary integration.
Actively seeking Software Developer / SDE roles (remote, onsite, or part-time). Passionate about clean code, scalable architecture, and delivering high-performance systems.
