Go engineer · ML infrastructure
I build the systems machine learning runs on, the ones that have to stay fast, correct and observable when the traffic is real. After hours I take old games apart and rebuild them as native programs.
01About
Models get the attention. Whether they work in production comes down to plainer questions. Does the feature arrive in time? Is the prediction the right one? When either goes wrong, can anyone tell? That is my part of the job: performance, correctness and observability, under load.
Before ML infrastructure I built high-load backends for analytics, social and survey products used by millions of people. The lesson carried over. A system is judged on its bad days, when traffic spikes, the data is messy and nobody has time to think.
02After hours
I love games, and I love taking them apart to see how they work. My hobby is bringing old games to modern machines as real native programs, by static recompilation. Nothing is emulated: the game’s original code is translated ahead of time into C++, compiled for today’s computer, and run on a rewritten version of the console’s system software. What comes out is an ordinary program: Vulkan graphics, any resolution, higher frame rates, today’s controllers. Right now that means handheld games from the PSP.
None of these projects ship game files. You bring your own copy. All of them are works in progress.
Port · Monster Hunter Portable 3rd HD Ver.
The furthest along. Start a new game or bring your PSP save, hunt, and play online with other hunters. It renders through Vulkan at whatever resolution you like, can interpolate frames up to your display’s refresh rate, and takes HD texture packs and community mods.
Framework · Recompiler and runtime
Pulled out of Yakumo so other games can use it: the recompiler, plus what the console used to provide. Kernel, system modules, a Vulkan renderer, audio, saves, ad hoc networking. A new game is a small profile on top.
EarlyGitHub
Port · LocoRoco 2
The first level plays through, recompiled and at full speed, and the game saves and continues. Only tried on macOS so far.

Port · Dragon Ball Z: Tenkaichi Tag Team
The newest. It boots and draws its title screen under the interpreter; the recompiled build runs but does not draw yet.
