HI, I’M LUIS.

Code, with
curiosity.

SCROLL TO EXPLOREThere’s a little of everything.

I build things to understand them.
A developer exploring AI, thoughtful software,
and the space between an idea and “it works.”

Varagity

Your knowledge. A little more connected.

A self-hosted RAG system that turns a document collection into grounded, cited answers. It combines semantic and keyword search on local GPUs, with an evidence panel that lets you follow each answer back to the passages it used.

03 / THE PERSON BEHIND THE CODE

A builder.
A perpetual student.

I’m Luis, a developer with a background in computer science and data science. I like getting under the hood: figuring out how systems work, then seeing what I can make with them.

Lately, that means agents and retrieval-augmented generation. But I’m just as happy getting lost in an algorithm, a security problem, or the details of a good interface.
