Full-Stack & Blockchain Engineer with Deep Smart Contract Security

Active over a week ago
🌱 Member since March 2026

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) Frontend applications (React, Tailwind.cssNext.js, TypeScript) Over the past few years, I’ve specialized in DeFi architecture and smart contract security analysing invariant violations, vault accounting models, and protocol-level risks across competitive audits and independent research.

I bring both:

A builder’s mindset — shipping reliable systems An attacker’s mindset — stress-testing assumptions If you’re building blockchain products, DeFi infrastructure, or Web3 applications and need engineering depth with security awareness, let’s connect.

Tell us a joke?

Two smart contracts walk into production. One says, “I passed all tests.” The other replies, “Unit tests or reality?”
