Welcome to my website.

I’m a old seasoned product and project manager digital carpenter. In recent years I became a tech serial startup entrepreneur; which means I use an IDE steer a team of AI agents in the morning and update look at spreadsheets in the afternoon.

I work for Tautos developing SaaS lightweight tech tools that help small companies boost their productivity.

On weekends, I enjoy going out with my two children, riding my bike around São Paulo city, programming on hobby projects and reading books.

This website is a patchwork that contains hundreds of items like posts, tools, calculators, lists, rankings, useful memes, books from the Bible, complete online courses, historical manifestos copied from their original websites for digital preservation/curation and hidden Easter eggs.

I have written my first book, a sci-fi technical novel about computers and freedom. It is not yet published, but I am working on it.

I keep a log of random business ideas and projects I get involved with. I have a now page for the things I’m doing. I have a “Moving Interest” page where you can see what I am up to these days. I write essays every once in a while, here is a longer list of blog posts.
