Hello, netrunner.

// principal engineer · real-time graphics · typed languages

I’m Jérôme Mahuet. By day, I’m a Principal Engineer working on the systems behind a social-media analytics product. Off the clock, I’ve built tiny worlds, interpreters, and games to understand how things work from the inside.

This is the backup of my brain: part notebook, part graphics lab, part neon-lit alley. Expect rough edges, useful detours, and the occasional glitch that teaches me more than a flawless run.

Time moves in one direction, memory another. We are that strange species that constructs artefacts intended to counter the natural flow of forgetting.

About me

I’m a Principal Engineer at Iconosquare, based in Limoges, France. My professional work sits at the intersection of software design, technical direction, scalable backend and frontend systems, and mentoring.

My personal work leans toward real-time graphics, voxel worlds, and typed languages. I like moving between the high-level shape of a system and the low-level details that make it feel alive: C and Raylib, OpenGL, learning notes on Vulkan and OCaml, Rust, and Haskell.

Deus Ex in the browser runs the original 2000 Deus Ex in a browser tab, straight from a local install. A JavaScript reader parses the Unreal Engine 1 packages, a Rust interpreter compiled to WebAssembly runs the game's own bytecode, three.js draws it on WebGL2, and every translated piece of the engine has to match the original, checked against its DLLs in an emulator and against the running game.
