Mathéo Delbarre

Systems / Compiler / Backend Engineer

PortfolioEmailGitHub


Computer science student (Year 2 @ EPITECH) focused on low-level systems, compilers, and backend engineering. I specialize in building complex systems from the ground up, with a strong emphasis on LLVM infrastructure, runtime environments, and performance optimization.

Interests

Cybersecurity • Compilers • Runtime Systems • Databases • Distributed Systems • Rendering Pipelines

Stack

Rust C++ C LLVM Linux Docker


Selected Projects

LLVM-backed compiled programming language written in C++.

  • Engineered a custom front-end, parser, and static type system.
  • Built an LLVM IR generation pipeline supporting both JIT and AOT execution.
  • Implemented pattern matching, lambdas, and control-flow analysis.

Plugin-oriented arcade runtime built in C++.

  • Architected runtime polymorphism using dlopen / dlsym / dlclose.
  • Designed strict ABI-stable interfaces for dynamic loading.
  • Abstracted rendering backends (SDL2, SFML) loaded dynamically at runtime.

Scalable, single-threaded server in Rust.

  • Implemented a non-blocking event loop multiplexing hundreds of concurrent TCP clients.
  • Engineered a custom protocol for channels, threads, and direct messaging.
  • Designed async networking primitives and internal protocol abstractions.

POSIX-style shell implementation in C.

  • Built a tokenizer and AST-based parser.
  • Implemented pipe and redirection support alongside robust process management and orchestration.

Security & Achievements

  • Top 5 / 90 - Binary Exploitation CTF: Demonstrated proficiency in stack/heap overflows, GOT overwrites, ROP-style chains, and reverse engineering against custom Linux binaries.
  • Software Engineering Intern @ AT7 Système: Modernized legacy enterprise software, secured public surfaces with Nginx, and containerized internal services.
