Rajdeep S.

I build secure, scalable, production-ready systems across blockchain, backend, and DevOps. My work spans smart contracts, Solana programs, zero-knowledge workflows, backend APIs, and cloud infrastructure. I have hands-on experience with Go, Solidity, Rust, Noir, and Circom, along with Hardhat, Foundry, Slither, Aderyn, Docker, AWS, and GKE. I help teams ship reliable products in areas like: Smart contracts and protocol development Solana apps and on-chain workflows ZK proofs and privacy-preserving systems Backend engineering with Go, PostgreSQL, and APIs DevOps, CI/CD, deployments, and infrastructure hardening Recent work includes building decentralized AI and fan-engagement infrastructure, privacy-preserving proving systems, secure storage integrations, and blockchain-powered backend services. If you need someone who can own both the code and the infrastructure, I bring the full stack needed to ship fast and ship safely.
