How we started a podcast

A week ago my friend Pablo and me released the very first episode of Code && Beyond. None of us had any experience in podcasting or ever worked with voice and audio. But we did that!


Code && Beyond

Code && Beyond

A (semi)weekly podcast with my friend Pablo and me, two software engineers with more than 35 years of professional experience combined. We talk about creativity, productivity, problem solving, tools, culture, and anything beyond, but still related to the daily life of a software developer.

Give it a listen at or in your favorite podcast player.
