Full Stack, Blockchain Engineer And Security Researcher

I help teams build secure, scalable blockchain and backend systems that don’t break in production. From writing and securing Solidity smart contracts to designing APIs and full-stack applications, I ship systems that are both functional and attack-resistant. I’m a Full-Stack, Blockchain Engineer and Security Researcher with 5+ years of experience building production grade software across Web2 and Web3. I work across Smart contract development (Solidity, EVM, Move), Backend systems (Node.js, Express, APIs, MongoDB), and Frontend applications (React, Tailwind.css, Next.js, TypeScript). Over the past few years, I’ve specialized in DeFi architecture and smart contract security analysis in variant violations, vault accounting models, and protocol-level risks across competitive audits and independent research.
