I'm Otávio (pronounced O-TAH-vee-o), a Physicist and Software Engineer from Brazil, now residing abroad for over ten years. My professional focus is on developing software for macOS and iOS, though I have significant experience with Linux and Embedded Systems as well.
Recently, I've consciously reduced my activity on traditional social media channels, opting instead for platforms like this blog and Mastodon, while stepping away from Instagram, Facebook, Twitter/X, and Pinterest.
