I audit smart contracts, research vulnerabilities, and build full-stack Web2 and Web3 applications.

I've contributed to smart contract audits and bug bounty triage at Nethermind, reviewing Solidity, Rust, Clarity, C++, Move, and C codebases. I also built an AI agent to support software development workflows and smart contract security analysis.

At Manakdigital, I delivered full-stack applications across fintech, edtech, healthtech, and e-commerce using React, TypeScript, Node.js, and Stripe. I converted a React SPA to SSR for SEO and dynamic Open Graph images, integrated AWS S3 and CloudFront, and built tools including a user-activity tracker, link-auditing crawler, and video marketplace backend.

I've developed 20+ Solidity smart contracts and Web3 DApps, with hands-on testing in Foundry and Hardhat. My security work includes bugs found through Code4rena, Cantina, and Sherlock, alongside hackathon awards and a Cartesi grant.
