Senior smart contract developer building secure, scalable DeFi, NFT and cross-chain systems.
ZimbabweWhat I'm looking for
I am a Senior Smart Contract Developer with six years of experience designing and implementing decentralized applications, DeFi protocols, NFT marketplaces, and cross-chain interoperability solutions. I combine deep technical expertise in Solidity, Ethereum/L2 ecosystems, and advanced security patterns to deliver production-grade protocols.
My work includes building intent-based systems, algorithmic stablecoins, CDP models, AMMs, ERC-4626 vaults, and royalty-enabled NFT standards, and I’ve led audits and applied upgradable contract patterns (UUPS, Transparent Proxy, Beacon) to ensure resilience. I optimize gas and storage for large-scale deployments and integrate DeFi primitives such as Aave, Compound, Curve, and Balancer.
I mentor engineers, create developer tooling, and collaborate across teams and ecosystems (Polygon, Arbitrum, Optimism, Cosmos, Sui) to drive adoption of cross-chain frameworks and innovative on-chain mechanisms like MEV-time oracles and privacy-preserving techniques.
