Felix Colbert

Delivered a DeFi protocol suite including staking, lending, and rewards across Ethereum, Polygon, and BNB Chain. Designed modular Solidity contracts with upgradeability and multi-chain support, collaborated with front-end/back-end teams to ship Web3 platforms, and reduced gas usage by up to 30% through benchmarking and contract optimization. Mentored junior developers and tested with Foundry.

Built backend infrastructure for institutional-grade DeFi analytics and real-time blockchain data. Developed backend services in Python and Go for aggregating on-chain metrics (e.g., Uniswap, Compound, MakerDAO). Improved API performance and latency for clients consuming DeFi protocol data, and helped scale backend systems to handle rapid data growth across DeFi protocols.

Worked with startups and established teams to design, build, and launch full-stack Web3 products. Delivered EVM-based DeFi platforms (staking, lending, rewards) and multi-chain smart contract integrations, and integrated Solana smart contracts using Anchor and wallet flows (e.g., Wallet Adapter, Phantom). Built and optimized staking/DeFi infrastructure, and reduced gas usage via benchmarking and contract optimization. Shipped front-end applications using React/Next.js/Tailwind with Web3 wallet integrations (e.g., Wagmi, Web3Modal, Solana wallet adapter).
