Skills Summary

At 27, I am seeking opportunities as a Solidity developer with a very good understanding of Solidity and Foundry for testing, also specialized expertise in Blockchain aspects, particularly Ethereum. I understand EVM/Bytecode and have some knowledge in JavaScript, Java for Android, and Python for Deep Learning. I have set aside the latter languages to focus solely on Solidity and other useful languages for Ethereum.

Since 2017, I have been actively engaged in learning about Blockchain and Solidity. I began my professional career as a developer in 2021, conducting Quality Assurance (QA) reviews and identifying bugs in Smart Contracts through Bug Bounties sites such as Code4rena and Codehawks.

Currently, I am developing a protocol dedicated to Decentralized Finance (DeFi) and Governance. I have completed the Minimum Viable Product (MVP) and the first iteration, and am now conducting tests using Foundry.NoTax-Protocol

I have prior knowledge in computer hardware maintenance.

Fluent in English and intermediate proficiency in French (B1/B2).
