@marcelclarembaux
Blockchain security researcher and Solidity developer focused on DeFi. Developer Relations Engineer
What I'm looking for
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.
