Hi, I'm Mauricio — a product person who's built at early-stage fintechs that punched above their weight. I get the problem right, then I get it out the door. Fueled mostly by coffee.
Side projects, shipped end-to-end on my own time. It's how I test whatever new tool or model shows up, on something real that I own.
Household finances with your partner.
Upload your bank statements and it handles the rest: a running balance between you and your partner, every transaction categorized by an LLM engine with a real evals harness behind it, and cryptic bank descriptions turned into clean vendor names. Built end-to-end and held to the same bar as anything I'd ship at work — I'm not going to manage my money with a tool I don't trust.
Keeps your Mac awake. That's it. That's the app.
I run agents in long sessions, and my Mac kept dozing off in the middle of them. Plenty of keep-awake utilities exist already. None of them come with a little pixel companion that drinks coffee on your desktop, so here we are. It does the keep-awake part properly, using macOS power assertions instead of wiggling your mouse around. No dependencies, no network access.
A memory layer built from plain text files.
Context files, skills, and a task system that Claude and I both read and write — it gets better every time I interact with it. It runs my product work, this blog, and the one-off sessions I keep turning into reusable workflows. The piece that syncs everything across devices became its own open-source tool.
This site is one of them too, built the same way. Read why
