ABOUT

Who

19, student at IPSSI (2025‑2028), Paris. I build security tools that actually solve real problems. I’m fascinated by how code breaks and how systems fail.

Am

I’m from Annecy, now living in Paris for my studies. I learn by doing, testing my own projects, and hunting for flaws. I move a lot—not randomly, but to explore, understand, and create.

I

Pragmatism above all. Build, fix, document. My code solves real problems, not egos. Hard bugs, broken systems… that’s where I learn the most.

http-garden

Differential HTTP analysis engine. Research on request smuggling by comparing parser interpretations across Nginx, HAProxy, and Gunicorn using AFL++.

  • Fuzzing: Differential analysis using AFL++ on multiple targets.
  • Trophies: Found vulnerabilities in HAProxy (CVE-2023-40225) and others.
  • Environment: Composable Docker architecture with custom Python REPL.

Password Analyzer

Built because I got tired of guessing password strength. Entropy scoring that actually works, pattern recognition for keyboard walks, predictable substitutions. Estimates real-world crack time using GPU benchmarks.

  • Scoring: entropy-based strength with practical heuristics.
  • Patterns: detects keyboard walks and common substitution habits.
  • Estimation: crack-time approximation using GPU benchmark baselines.

Web Vuln Analyzer

My first real security tool. Automates the boring part, testing. Finds SQLi, XSS, CSRF, path traversal, parameter pollution. The insight: generate context-aware payloads.

  • Automation: crawl + test loop to reduce manual recon.
  • Coverage: targets SQLi, XSS, CSRF, traversal, parameter pollution.
  • Payloads: context-aware generation rather than naive fuzzing.

Steganography Toolkit

LSB steganography, EXIF manipulation, metadata injection. Hide data in images imperceptibly — the eye won't catch what statistics can't explain.

  • Techniques: LSB steganography + EXIF/metadata manipulation.
  • Workflow: hide + extract utilities designed for real scenarios.
Python PIL Processing

Interactive Narrative Engine

Passion project. Interactive fiction engine built on state machines. Branching dialogue with real consequences. Built to prove a thesis: games and serious tools are the same architecture.

  • Core: state-machine driven story logic.
  • Design: branching dialogue with meaningful consequences.
  • Architecture: tool-like structure applied to game systems.
