ByungHyun21

Developer interested in running large language models locally — the hardware, the software, and everything in between.

I believe the most interesting computing happens at the edge, on your own silicon, with your own data.

With My Hardware
Runs open-weight models in production
Concurrent multi-slot serving with speculative decoding and long-context support — tuned, benchmarked, and debugged down to kernel level.
Owns every layer of the stack
From GPU kernel modules to serving infrastructure. No layer I haven't had to open.
Keeps AI data on-premises
Inference, agent execution, result collection — the entire pipeline runs on hardware I control. Sensitive data never touches a cloud.
