I'm a fullstack developer in Barcelona, currently working at Pensero. I have a habit of turning small everyday annoyances into focused apps, web tools, and hardware projects.

I like local first software, useful products with a small scope, ESP32 experiments, home automation, and 3D printing. I share the messy middle not just the launch on X and Instagram.
