What I'm looking for

I seek roles focused on blockchain security, smart contract auditing, and DeFi monitoring where I can combine hands-on Solidity work, research, and developer education to strengthen protocol safety and grow technical communities.

I am a research-driven blockchain developer and security researcher specializing in smart contract development, auditing, and DeFi infrastructure. I combine deep technical skills in Solidity and EVM internals with a background in psychology to produce clear documentation and educational content.

I have developed monitoring bots and auditing tools using Forta, Foundry, and Solidity, and authored technical tutorials and research, including work on quantum-resistant algorithms for DeFi. I participated in Cyfrin programs and competed in Cantina audit contests and bug bounties to hone my audit reporting and PoC abilities.

In developer relations, I created technical documentation, onboarding materials, and community management structures for Bunzz, helped secure investor meetings, and contributed to a $4.5M seed round. I have overseen DEX operations and provided strategic guidance and UX feedback for DeFi projects.

I am an educator and contributor — publishing The Blockchain Security Monk, producing Forta bot development course content, and contributing to Cyfrin's GitHub. I seek roles where I can apply security research, monitoring, and developer-facing communication to strengthen DeFi systems.
