About me

I'm Johnny, a web developer based in Barcelona. Father of two (Naiara and Erik), tech enthusiast and maker of things that try to make people's lives better.

I've been coding professionally for 10 years, currently working on BBVA's mobile app. In my spare time I'm building OhanaSmart, a smart vending system for healthy food.

I also run (training for my first marathon), grow lettuce with hydroponics and experiment with AI agents. This blog documents part of that journey.
