I’m a backend-focused developer with hands-on experience building scalable RESTful APIs, Django-based backends, and role-based access control systems. I enjoy designing microservice-friendly architectures and integrating ML models while working end-to-end from database design to deployment.

In my internship, I designed and deployed 25+ scalable RESTful APIs using Django/Flask and PostgreSQL, supporting 10k+ records with optimized query performance and granular role-based access control. I also built asynchronous task workflows for activity tracking and automated email notifications, improving system responsiveness and user engagement.

I’m energized by ownership and fast-moving teams—whether that means collaborating with frontend teams to resolve production-level issues (like CORS and DB constraints) or documenting features for knowledge sharing. My projects reflect the same mindset, from an end-to-end diabetes risk ML pipeline to a Django e-commerce backend with Elasticsearch search and RazorPay payments.
