I’m a Full Stack Software Engineer and MCA candidate currently interning at Infosys Springboard, where I engineer production-grade platforms end to end. I focus on shipping real features quickly—while keeping security, performance, and clean architecture non-negotiable.

In my internship, I architected FastAPI microservices with an Angular frontend across 11 modules, covering vendor registration, procurement workflows, purchase order tracking, and contract compliance. I designed JWT Authentication and OAuth2-based RBAC for six user roles, securing 20+ REST API endpoints with least-privilege access control.

I’ve also optimized system performance by tuning a PostgreSQL schema with SQLAlchemy ORM and Redis caching. The result is faster APIs (targeting sub-300ms responses) and an approach built for concurrency, validated through project benchmarks and hands-on Agile delivery across 8 sprints.

Beyond work, I build with curiosity and rigor: I engineered a concurrent Python NLP processor (tokenization, keyword extraction, normalization) using multi-threading and multiprocessing, and I integrated a multilingual translator using a Sarvam AI REST API. I also created a real-time weather app using OpenWeatherMap and async JavaScript to update the UI without page reloads.
