Welcome to my developer page on GitHub! My name is Raul Bras and I live in this surreal country we call Brasil. I have a degree in information technology (computer science), and I work in the business intelligence segment as IT Business Analyst.

I've started a long-term personal venture to gradually replace preinstalled Android apps with my own privacy-focused alternatives. I'm concerned that Big Tech companies are increasingly hungry for personal data, tracking everything they can with little regard for users' privacy. I'm developing independent, secure, and transparent apps, one at a time.

Below is a list of my active projects and experiments. These repositories represent my current focus on software engineering. Feel free to explore the source or reach out if you're interested in collaborating.

• 🤬 Castas • Affective Polarization Test. The purpose of this app is to offer a diagnostic tool for one of the most challenging phenomena in modern democracies: affective polarization.

• ✨ Skills • AI Agent Skills. My personal collection of skills and prompt templates for guiding AI agents through software specification, development, and review — making the process more consistent, efficient, and aligned with user needs.

• 🐝 Yo-Fi • Online Chat Over Wi-Fi. Android mobile application for sharing Wi-Fi access between individuals and businesses, and transferring messages.
