Software Developer in Leiria, Portugal

Member since April 10, 2020
Luis has been building for the web for over 20 years and can work on the full-stack but his best work is on the front end. He likes to think about the big picture but always feels the strong need to understand how the little pieces work in detail. Luis is used to working remotely and communicating with distributed teams in multiple timezones. He's familiar with both startup and enterprise development environments.
