.NET Developer at 3FITECHCOMMUNICATIONSPVTLTD building e-commerce APIs and payment integrations.

At 3FITECHCOMMUNICATIONSPVTLTD, I develop .NET Core backend architecture for an e-commerce platform covering product catalogs, inventory, orders, and user management.

I built RESTful APIs for cart and checkout operations and integrated Stripe, PayPal, and Razorpay, including webhook handling. I also implemented JWT authentication and PCI DSS-compliant payment processing.

Earlier, as a .NET Developer Intern at 3FITECHCOMMUNICATIONSPVTLTD, I created APIs for cryptocurrency transactions, wallets, and real-time price feeds. I used SQL Server and Entity Framework for data operations and documented APIs with Swagger.
