about
I'm Rey John, a software engineer. I build mobile, web, and desktop applications, along with the backend services that power them. At work, I focus on card-based payment products.
Alongside that, I freelance for teams in the Philippines, building apps, web platforms, desktop tools, and internal software. I also make games in Godot.
