Blockchain Developer | DeFi & Security | Data-Driven Approach
My portfolio showcases a unique journey from data analysis to blockchain development, where analytical rigor meets Web3 innovation.
I build secure smart contracts and DeFi protocols using Solidity, Foundry, and advanced testing frameworks. Each project combines technical excellence with strategic thinking, from tokenomics design to security auditing.
My 4 years analyzing financial data, optimizing tax strategies, and assessing risks now powers my approach to blockchain: designing economically sustainable protocols, writing comprehensive security tests, and identifying vulnerabilities through rigorous analysis.
