What I'm looking for

I seek hands-on roles building Web3 and DeFi products where I can design secure smart contracts, optimize performance, and ship end-to-end solutions in collaborative teams.

I am a Full Stack Developer and Blockchain Engineer with hands-on experience building scalable Web3 applications, DeFi protocols, and AI-integrated systems. I have developed smart contracts across EVM and non-EVM chains and implemented decentralized backends using Rust and canister frameworks.

My projects include an ERC-721 based land registry, a cross-chain perpetual trading platform with Chainlink oracle integration, and a collateralized stablecoin with robust economic safeguards. I also built RAG systems combining vector embeddings with LLMs and multiple production-ready frontends using Next.js and React.

I deliver end-to-end products from architecture to testing and deployment, leveraging tools like Foundry, Hardhat, IPFS, and AWS. I bring a strong focus on test coverage, performance optimization, and secure smart contract practices to accelerate product delivery.
