Description

Application security engineer with 6 years of experience, I have extensive experience in the security of high-stakes economic applications.

Additionally, I also possess expertise in auditing web3 applications (EVM and Solana).

My ability to communicate fluently in French and English allows me to ensure smooth communication, thereby facilitating collaboration on various audit projects, from target definition to the implementation of corrective measures.
