Hi there! I'm Joe.
I build software and measure AI on hardware I own, then publish what actually happened, run logs included.
CAIO [Local, Enterprise] by day. After hours it’s the home lab: one RTX 5090 & EVGA 3090 ULTRA, vLLM and llama.cpp, and a growing pile of run logs. This site is the public notebook for both.
A few things about me
The rig
NVIDIA GeForce RTX 5090 (32 GB), AMD Ryzen 9 9950X3D, 64 GB DDR5. One box, one GPU, no cloud credits.
The bench model is for the 3090, goal is test how Ampere quants hold up against Blackwell, hoping to lower barrier to entry.
Everything on the bench page was measured on it.
Numbers over vibes
Every benchmark here ships with its methodology and run log. Determinism is checked, not assumed: identical runs have to produce identical output before a result counts.
Day job
CAIO [Full Stack = Local AI in prod].
After hours
Squeezing more out of the 5090/3090: quantizing a 27B hybrid model until a whole novel fits in one prompt, and writing up the four walls that stood in the way. The wins and the regressions both get published.
Shipped things
The projects page is the portfolio: live links, source, and the story of how each one was built.
Say hi
Email is the best way to reach me. Twitter is another great place, find me @JoeGuglielmucci
Now
- Building a GGUF quant ladder for Qwen3.8-27B that reports what no card does: thinking tokens per tier, MTP acceptance, and n on every number.
- Writing up the reading behind it: the denominator rule, the context arithmetic, and what the discussion tabs actually complain about.
- Day-job product work in JavaScript and TypeScript. The commit chart below is mostly that.
