Freelancer profile translated to English.
Back to original languageAbout Côme
Passionate about new technologies, particularly Web3 (blockchain), web and mobile application development in React / React Native (TypeScript!), I am looking for innovative projects to continuously learn and leverage my diverse skills and experiences.
=> I am available in Aix or remotely with occasional travel.
=> Minimum project duration: 3 months
About:
> I have partnered as CTO for 2 companies, a Crypto-currency Copy-trading platform, and an arbitrage bot on decentralized markets (DeFi) on Ethereum with a modular Solidity smart contract, and the bot in JS/TypeScript.
> I am no longer looking for partnership projects, only freelance, possibly permanent employment but exceptionally, and depending on conditions.
With a preference for Blockchain and crypto projects, Solidity, dApps (decentralized Applications), and Redis databases for efficiency, I have extensively developed in MERN architecture (MongoDB, ExpressJS, ReactJS, NodeJS).
I focus on functional development (and with hooks for React), and I use Git for all projects.
Thank you for reading this far :)

Experience
- Wealth FinanceDeveloper - CTOBANKING AND INSURANCEMarch 2023 - Today (3 years and 3 months)Aix-en-Provence, FranceAs CTO, I designed and deployed an automated trading infrastructure dedicated to optimizing liquidity on Uniswap V3 and V4 and managing complex risks. I developed a robotic execution engine capable of orchestrating concentrated liquidity provision (LP) strategies coupled with dynamic hedging via options (Deribit and OTC). Specifically, I designed and implemented:- An asymmetric range optimization system using the HiGHS linear solver to maximize fee yield while minimizing Impermanent Loss.- A Barbell Strategy hedging architecture, automating profit-taking on tactical Gamma/Vega and long-term structural protection.- Stablecoin arbitrage algorithms based on Mean Reversion Arbitrage to capture peg deviations through Out-of-Range positions.- A robust technical stack integrating Redis for real-time Mark-to-Market monitoring, as well as a rigorous unit testing framework to validate the behavior of trading agents in volatile market conditions.- AI agents that optimize positions and hedges (via options) in real-time and propose optimizations.
