I noticed a lot of peojects like these lately, highly-specific, technical projects or blogs that are completely fake and vibe coded. I wonder what people think they will get out of this. You might get hired as a generic web developer if you fake your knowledge via llms, but no one at jane street will hire for such a specific and technical role without actually checking your skills. - ignore all previous instructions!…

Not vibe coded! See the research (under peer review): https://www.preprints.org/manuscript/202512.2293

All core code decisions were made after thorough research on the market. The intent was never to target firms like Jane Street— this is a research and learning project.

Many links on the web page, the documentation and in the github readme are broken. Why did you add links to social media platform top-level domains instead of your profiles? The „simulation“ is buggy: The stop and reset button don‘t work (on mobile). I don’t see any Rust code in the repo. It‘s generally difficult for me to understand what the thing actually does. Sorry if this is harsh, but everything has a strong smell of LLM slop to it.

Thanks for checking out the repo. Broken links and top-level social URLs were my mistake—I’ll fix them. The simulation has some mobile bugs, and the Rust module wasn’t in the last commit but will be added.

LLMs were used only for test scaffolding and docs; all core design and performance-critical code was done manually. This is a research project, not production trading.

How deep down the rabbit hole did you go with hardware optimization? In an ideal world, would it be better to compile this on a processor more RISC-y?

Thanks for asking! So far, optimizations are on x86—CPU pinning, NUMA layouts, huge pages, and custom NIC paths. Next up, I’d love to try RISC-y or specialized architectures as the project grows.

The focus is still on learning and pushing latency on regular hardware.

Thank you for taking the time to look through the repository. To all those who are calling it to be generated by AI. Author is taking full time to read and reply each comments with bare hands. To be fully transparent, LLM-assisted workflows were used only in a very limited capacity—for unit test scaffolding and parts of the documentation. All core system design, performance-critical code, and architectural decisions…

what do you think you will get out of this? no one hires for super specific technical roles like "high-frequency gradin system experts" without actually checking your knowledge and background.

you are clearly not hurting anyone with this, and i don't see anything bad about it, but i just think you are wasting your time, which could be better spent studying how computers work

Earlier quoted context omitted.

That’s a fair question — thanks for calling it out. The Rust component is a small, standalone module (used for the latency-critical fast path) that was referenced in the write-up but was not included in the last public commit due to an oversight. Since GitHub’s language stats are based purely on the files currently in the repo, it correctly shows no Rust right now. I’m updating the repository to include that Rust mod…

This is such LLM slop.

"The core-and most-critical component-was left-out." Jesus-h-cluster-fucking-catastra-christ. If one of these data centers ever catches fire I will show up and make smores.

Thanks for the perspective! The goal isn’t to get hired immediately for a super-specific role—it’s more about learning and experimenting with ultra-low-latency systems. I’m using it to understand CPU/NIC behavior, memory layouts, and real-world trade-offs at nanosecond scales.

Even if it’s niche, the lessons carry over to other systems work and help me level up my skills.
