Available to hire
I’m Carlos Fuenmayor Palacios, software engineer with over 16 years of experience on software development, specially on Backend side. I’ve participated in diverse projects with multiple clients, performing a variety of tasks ranging, going from architecture and design of new cloud implementations to code maintenance and testing.
I believe two of my most significant qualities are my ability to find out how to solve problems, even in completely unfamiliar scenarios and technologies; and my soft-skills, I’m way communicative, enjoy teamwork and I’m always available to help.
