A selection of what I've built: production systems, open source tools and experiments.

Backend and APIs for a solution connected to UNESCO's Media and Information Literacy Cities initiative, focused on business rules, data structuring and application robustness.
Internal tool for process optimization, built during my time at Aupi Soluções.

GNOME Shell extension to track daily water intake: goals, reminders and one-click logging right from the top panel.
Static Cookie Clicker save vault with a Gist-inspired UI, editable gallery and a steganography puzzle.
