About Me

A constellation of experiences

Computer science grad from UCF, working across full-stack systems, ML, and real-time graphics. Most of my recent time goes into ytk, a personal knowledge system, and the experiment record that grew out of it. Before that: geospatial tooling for a land surveying company, a fintech R&D internship, and a lot of hackathons.

2026 - PRESENT

A personal knowledge system treated as a lab: everything I save becomes searchable, mapped, and measured

40+ numbered experiments on the production corpus, from embedding geometry to a native sparse autoencoder, published with figures and corrections
Retrieval eval gate runs before every commit: 156 frozen queries with known answers; regressions fail the build
The corpus rendered as an explorable galaxy, with coastlines drawn by measured nulls instead of by eye

The record

Numbered experiments on my own knowledge base. Figures first; each card opens the writeup.

Experiment 30My notes have a coastlineWhere does a knowledge base end? Drawing the border with a yardstick instead of an eye.

Experiment 12Every note points the same wayEvery note pointed the same way. Most similarity was a shared lean carrying no information.

Experiment 24Teaching my search index to explain itselfA sparse autoencoder that names real threads in the corpus, and honestly fails the retrieval gate.

Experiment 08The alarm that cried wolf every dayA quality alarm that fired on growth was retrained to fire only on breakage. Then sabotaged, to prove it.

Experiment 40Does my second brain pay rentDoes saved knowledge ever come back? Yes, through a channel built by accident.
