What I'm looking for

I'm looking to build production Web3 and DeFi products, especially smart contracts and full-stack decentralized applications across Solana and Ethereum.

At Nivix Pay, I build Solana infrastructure for decentralized healthcare records, including a Rust Anchor registry that anchors patient Merkle roots and doctor access delegations while allowing users to reclaim rent directly to their wallets.

I built the custom Merkle tree engine that hashes medical files and prescriptions without exposing PHI on-chain. I also integrated wallet authentication, DID-to-wallet linking, Express/Node.js services, Convex mutations, Devnet deployment, and Phantom transaction signing.

Previously, at ManoRekha Tech Innovations, I developed and tested smart contracts and helped design decentralized applications while working with blockchain networks, wallets, tokens, code reviews, and technical documentation.

I've also built an NFT marketplace on Ethereum and Polygon, a Solana lending and borrowing protocol, and SOUL-SIGHT, an oracle-driven cricket prediction market with on-chain settlement.
