Shiv Kumar

I’m a Software Engineer with 3+ years of experience building scalable, real-time blockchain applications and distributed systems. I specialize in backend development with Node.js and microservices architectures, and I’ve delivered production-grade systems for NFT marketplaces, real-time bidding platforms, and blockchain data explorers. I work extensively with EVM-compatible chains and WASM environments, implementing secure smart contract interactions (ERC-20, ERC-721, ERC-1155). I enjoy solving low-latency data processing problems using event-driven systems and stream platforms like Redpanda, and I focus on building reliable, production-ready infrastructure.
