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

A prominent part of my recent work is about making AI coding agents useful on our big internal codebases: repository instructions (AGENTS.md / CLAUDE.md), reusable skills, slash commands and MCP servers. I learned and taught team members to treat the coding agent like a new hire that we have to onboard, and then review thoroughly and iterate on both the code AND the skills!

This blog (source) is a small example of that process: have a look at its AGENTS.md, which documents the repository instructions and the skills I rely on here, including the MIT-licensed humanizer skill I run on every post. A longer write-up series is in the works and will show up under the ai tag.

For more advanced setups, see the following repositories:

• SQLiteC++: my long-running C++ library carries a similar set of project skills for its builds, tests and releases.
• pong-sdl3-cpp: an in-progress C++/SDL3 Pong I built mainly to exercise the process, with its own .claude/skills/, a roadmap, CI and unit tests.

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.
