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.
