Hi, I am Sébastien Rombauts, or SRombauts on Github. I am a Senior Software Engineer working on developer tools, C++, C#, Unreal Engine and Unity, source control integrations, and AI-assisted software engineering.

See also my developer blog (with the source portfolio).

Connect on LinkedIn or follow me on Twitter/X.

Main GitHub repositories

• SQLiteC++ (repo): a smart and easy to use C++ wrapper to the SQLite3 library.
• UE Git Plugin (repo): the official Unreal Engine Git Source Control Provider Plugin.
• UE Plastic SCM Plugin (repo): the official Unreal Engine Plastic SCM (Unity Version Control) Source Control Provider Plugin.
• UE4 Architecture Vis (repo): run a live demo in the browser using HTML5/WebAssembly. Click the image for the HTML5/WebAssembly live demo.
• UE4 Procedural Mesh: using the Unreal Engine 4 UProceduralMeshComponent.
• UE4 Quick Start: a mix of various Unreal Engine 4 C++ Tutorials.
• LoggerC++ (repo): a simple, elegant and efficient C++ logger library.
• HtmlBuilder: a simple C++ HTML DOM generator (used in a couple of embedded web services).
• SimplexNoise: a Perlin’s Simplex Noise C++ implementation (1D, 2D, 3D).
• shared_ptr (repo): a minimal, light and fast shared_ptr implementation designed to handle cases where boost/std::shared_ptr are not available.

AI-assisted software engineering

Most of my recent work is about making AI coding agents useful on real codebases: repository instructions (AGENTS.md / CLAUDE.md), reusable skills, slash commands and MCP servers. I treat the agent like a junior dev that we have to onboard, and then review thoroughly, argue and iterate.

• pong-sdl3-cpp (roadmap): a Pong clone in modern C++ with SDL3 and CMake, built from scratch without a game engine. It doubles as an AI-assisted methodology sandbox, with per-task skills, a written roadmap, cross-platform CI and a doctest test suite, each milestone sliced into small reviewable commits.
• This blog (source) is itself a small public example: have a look at its AGENTS.md for the repository instructions and skills I rely on.

A longer write-up series is in the works, see the ai tag on the blog.

Other experiments

Smaller things I have played with over the years: a Python Entity Component System, SDL game prototypes, OpenGL including gltext, Ogre 3D, and ZeroMQ C++ bindings.
