I built Paytm, a full-stack payment platform, with RESTful APIs for secure digital wallet transactions. I implemented MongoDB ACID transactions via Mongoose and JWT authentication with Bcrypt password hashing.
At Tata Consultancy Services, I managed Linux cloud servers and VMware virtual machines, and engineered customer support AI agents using Google AI Studio and webhooks. I’ve also developed a voice-enabled digital replica app and an HD wallet generator for Ethereum and Solana.
