At Payzon India Pvt. Ltd., I built and maintained backend systems with ASP.NET Core, including REST APIs and wallet and payment modules for real-time transactions. I also integrated payment gateways and created transaction logging and audit systems.
On fintech and blockchain projects, I implemented transaction lifecycle management, UTR tracking, and USDT wallet deposit tracking with TronScan and BscScan APIs. I also optimized SQL queries and built backend APIs for Proud1.live, a business listing platform.
