Hi! I’m Rubens.

I’m a developer who enjoys building software that is "good at what it does." I don't believe in overcomplicating things; I prefer tools that are lightweight, functional, and respect user privacy.

What I spend my time on:

Data & Science Communication: I’m passionate about making complex information easy to understand. I love creating visualizations that help people explore data and scientific concepts in an intuitive way.

Purpose-Built Automation: I develop small, focused tools designed to solve specific problems—whether it’s streamlining a workflow or generating documents efficiently.

Privacy & Open Source: I believe the best tools are the ones that run locally and keep your data where it belongs: with you.


Sponsorship helps me dedicate more time to maintaining my open-source projects and exploring new ways to visualize data. If you value software that is simple, private, and built with a focus on clarity, your support means a lot.
