Pedro is a full-stack programmer who often says, "I can make it work, not make it beautiful." Give him a design, and he can turn it into an application while working on the back-end side of fast-paced projects with short sprints—the ones he enjoys the most. He has experience with Python, PHP, and Node.js using many different frameworks. Pedro is also a proficient Linux user with a good knowledge of server configuration and management.
