Josman Pérez

Based in Dublin, Ireland · From A Coruña, Spain

I had the incredible opportunity to study for a year in Norway during my studies and work for a year in New York after graduating. My interests were directed towards embedded application programming, mostly Android and iOS natively as well as the IoT world. I focus mainly on product while keeping in touch with the consumer as well as the business. If I had to sum up my professional interests in one sentence, I could only say that I am passionate about technology.
