What I'm looking for

I seek roles building secure, scalable blockchain protocols or DeFi products, with emphasis on rigorous testing, audits, and collaborative teams focused on long-term reliability.

I am a Smart Contract Engineer with 4+ years of experience building secure, gas-efficient contracts and scalable architectures across DeFi, RWA, and NFT platforms. I design and implement composable protocols, upgradable contracts, test suites with 95%+ coverage, and collaborate with top security firms to harden critical systems.

I have delivered production-grade solutions for startups and established companies including Kickstarter, VIVEEL, and numerous freelance clients, led marketplace and lending protocol implementations, and optimized contracts for gas and security. I prioritize reliable testing, formal audits, and pragmatic architecture that balances platform-specific requirements with long-term maintainability.
