* about
me and how
i work
I'm Walter; a venezuelan PM living in Barcelona. I've spent the last decade building things on the internet, first as a developer, now leading product at eDreams. This is where I write about that work, about running long distances, and about figuring things out as I go.
Writing helps me think. If something here is useful or resonates with you, even better.
No polish, just honest notes from the process. Start with the blog, or say hi.
