Abstract

Researcher focused on decentralized computing, system security, and emerging technologies. My interests span from distributed architectures and software reliability to applied cryptography and privacy engineering.

With a background in full-stack development and R&D, I've built open-source tools, led cross-disciplinary projects, and currently oversee research and technical operations at RAID Square, contributing to innovation in cybersecurity and digital forensics.

Life Timeline

Present — CTO & Research

Currently leading all technical and research operations at RAID Square, a French leader in Web3 cybersecurity and cryptocurrency investigations. I oversee smart contract audits, blockchain investigations, and R&D efforts while contributing to Sinodevi, an open-source research initiative. My work focuses on DeFi protocol security, cross-chain systems, and advanced blockchain forensics.

2023 — Wabasen & Open Source Security

Developed Wabasen, a cross-platform file encryption software written in Rust for Linux, macOS, and Windows. The system integrates wallet-based 2FA authentication to enhance privacy and cryptographic security. Released as open source, Wabasen reflects my ongoing commitment to security tools that combine usability with decentralization principles.

2022 — Founding Sinodevi & RAID Square

Founded Sinodevi, an open research foundation dedicated to blockchain security and decentralized innovation. In August, co-founded RAID Square, which became France's leading company in crypto investigations and Web3 cybersecurity consulting. I introduced a technical marketing concept that recovered over $650,000 from the OasisDEX protocol by MakerDAO, developed a custom smart contract for asset recovery, and built an internal scanner that analyzed over 550,000 orders. Under my technical direction, RAID Square grew from 0 to over €1M in revenue in 3 years, completed more than 300 investigations(including collaborations with government agencies), and audited smart contracts securing several million euros .

2021 — Solana Hackathon & DeFi Engineering

Participated in the first Solana Hackathon and was recruited by a decentralized trading platform. Designed and implemented a Solana ↔ Ethereum bridge and a Binance ↔ Polygon oracle systemthat mirrored centralized exchange account performance on-chain, processing over 70,000 transactions. Also sold a metadata customization platform and contributed to a project focused on RWA tokenization.

2020 — From Security to DeFi

Decided to merge my cybersecurity expertise with blockchain technology. Started applying years of experience in hacking and development to crypto projects, identifying vulnerabilities and strengthening decentralized infrastructures. In June 2020, I discovered a critical vulnerability in Binance's payment systems. Later that year, I began contributing to open-source DeFi projects and research initiatives.

2019 — Arbitrage Systems & Early DeFi

Upgraded my CS:GO trading bot into an arbitrage system between skin trading platforms, executing thousands of automated exchanges. In mid-2019, a Singapore-based company acquired the project. Continued exploring decentralized finance, learning Solidity and React to create small DApps and blockchain experiments.

2018 — CS:GO ↔ Crypto Exchange Bot

Built a Node.js bot to exchange CS:GO skins for cryptocurrencies using the Steam SDK and Coinbase Pro API. The bot handled over 10,000 exchanges and several thousand dollars in transactions, becoming my first profitable automation project. Also learned reverse engineering with x64dbg and practiced software cracking for educational purposes to understand binary structures and protection mechanisms.

2017 — Game Development & Augmented Reality

Started programming small desktop applications in Visual Basic, then moved to Unity for game development. Created an augmented reality game that won a competition in 2018, strengthening my understanding of 3D systems, C#, and user experience design.

2016 — Bitcoin, Ethereum & Mining

Discovered Bitcoin and Ethereum while experimenting with mining using NiceHash. I was fascinated by blockchain as a technology, long before understanding its financial implications. This period marked the start of my technical curiosity about decentralized systems and consensus mechanisms.

2015 — Internship & First Freelance Project

Completed an internship in a major French company where I discovered Big Data and first heard about blockchain. My supervisor became a mentor and later hired me to build his e-commerce website. It became my first paid project the business now operates fully online with two physical shops.

2014 — Hacking & IT Discovery

I discovered computers and the world of hacking. I began experimenting with Kali Linux, Hydra, SQL injections, Tor, and the darknet. I tested everything I could from school networks to small company systems purely out of curiosity. This phase shaped my technical foundation and mindset toward ethical security research.

2013 — First Computer

Received my first computer, mainly to play GTA San Andreas. Since it wasn't powerful enough, I began exploring the system instead, learning CMD commands and understanding how operating systems worked my first true step into technology.

2002 — Genesis

Since I was a child, I've had a passion for woodworking. I wanted to become a cabinetmaker. I even sold some pieces of furniture I made when I was about eight years old. Unfortunately, this craft is fading away, and I quickly faced reality when I tried to get an internship, the only possible outcome was to end up working in a factory. So, I decided to keep this hobby as a passion rather than a professional goal.
