Indie developer in Portugal, shipping as Hexadexa. I build native macOS and iOS apps, Android apps, web platforms and automation tools. The apps run without accounts, telemetry, or anything in the middle.
Before code there were 15+ years in audio and video: live events, sound design, post-production, with IT running alongside the whole time. Most of what I make starts as something I need myself, then grows into something others might find useful too.
