Background

I’m Brazilian and have lived in Portugal since 2024. I’m a full-time pastor and IT technician, with a degree in IT Management, an MBA in Information Security and a postgraduate degree in Full Stack Development. I also work with artificial intelligence, machine learning and website and app security.

Before tech, I spent nine years as a volunteer coordinating teams and social projects in twelve countries. It taught me to listen, adapt and deliver — and that’s how I approach every project.

I help businesses, local shops, associations and churches build a professional online presence: design, development, hosting, domain, email and maintenance.
