About Me
Hey! I'm David—a developer who genuinely enjoys building things. Whether it's a payment solution for small businesses or a platform helping workshop organizers manage their events, I find satisfaction in creating tools that solve real problems.
During the day, I lead the tech team at Vexl, where we're building something I truly believe in—a way for people to trade Bitcoin privately, the way it was meant to be. The intersection of technology and privacy is something I care deeply about.
When I'm not coding, you might find me making music under the name Artific. It's a different kind of creative outlet, but the process of building something from nothing—whether it's software or a track—feels surprisingly similar.
I'm based in the Czech Republic, always curious, and constantly working on the next thing.
