Message

On Shiksha, I contribute to database architecture and backend services for course content and self-assessment features across web and cross-platform clients as part of a 15-developer team.

For Redgear Merch, I fixed an inventory concurrency issue by putting stock validation and updates in a single database transaction. I also contributed to storefront and order-management services and improved product-listing performance with PostgreSQL indexing and pagination.

I’ve also worked on React.js interfaces for a real-time bidding platform and resolved performance bottlenecks for the Squid Game Event web experience. In my projects, I built NeuralByte AI with Google’s Gemini API and independently migrated BingeShow’s authentication from Clerk to Auth0.
