Guifré Ballester

Once I co-founded my first startup, I found my passion. I consider myself an enthusiastic Product Manager with an entrepreneurial personality and strong tech background. My main skills are analysis, prioritization and business strategy. I’m used to work hand by hand with tech leads, developers and different stakeholders looking for excellence. My goal is to provide customers the product they deserve. Right now, I’m working as a Product Manager @ Stayforlong's Barcelona offices. Here, we're reinventing the "long" travel industry, by providing better conditions when staying more nights.

Interests

Apart from being a Product Manager, I enjoy most of my time being outdoors. I am an avid runner, where I prefer trail over asphalt races. What takes the best of me are the obstacles races like spartanrace. In the winter, I am a novice alpinist. During the warmer months here in Catalonia, I enjoy adventure sports.

When forced indoors, I follow a number of sci-fi and fantasy genre books, movies and television shows; I am an aspiring chef, and I spend a large amount of my free time exploring the latest technolgy advancements in the Deep Learning field.
