Work experience & achievements
As an independent Vyper Smart Contract Developer and DeFi Engineer (self-employed since February 2024), I have been fully focused on designing, building, and securing production-grade decentralized finance infrastructure on Ethereum and compatible chains. Key achievements include: Architecting and deploying multiple DeFi primitives: NodeJackPot (provably-fair Chainlink VRF raffle system), KhomDev Keep (ERC-4626 multi-strategy USDC vault with dynamic tranching across Aave, Compound, and Morpho), Coil DEX (off-chain intent batch auctions), VeForge (vote-escrowed tokenomics engine), and TARE (overcollateralized ETH-backed stablecoin). Heavy emphasis on security research and best practices: implementation of reentrancy protection, pull-over-push payment patterns, comprehensive invariant and stateful fuzz testing (Hypothesis + Moccasin), 100% test coverage where applicable, and formal verification patterns. Development of supporting AI-powered tools for on-chain monitoring, narrative gener
