About

I am a Backend and Blockchain Developer with 4+ years of experience building scalable systems using Node.js and TypeScript, along with hands-on experience in Solidity and DeFi applications. I have developed backend microservices, smart contracts, and blockchain integrations across Ethereum and Polygon, with strong exposure to AWS, Docker, and API design. I focus on building secure, high-performance systems and enjoy working on real-world DeFi use cases.

Experience

Worked as a Blockchain/Backend Developer where I designed Node.js microservices, developed and integrated smart contracts, and managed blockchain nodes and AWS infrastructure. Built REST/GraphQL APIs, handled database design, and ensured security using cryptographic standards. Also improved system performance and automated deployments using Docker and CI/CD.
