Hi, I’m Javi.

I’m a developer, tech lead, and recovering designer who has been shipping things for more than 20 years. Still learning, though.

I'm passionate about building products people actually want to use, not just software that technically works.

Here you’ll find what I’m working on, what I’ve built, and the occasional write-up about code, AI, and tooling.
