Sebastian A. EspindolaBack End Developer
I am a devops engineer with over 20 years of experience working with Linux & Unix. I like to continously investigate and learn new technoligies in order keep myself updated with the latest developments of the IT industry. In my years of experience I have worked from small to Fortune 50 customers in many industries, so I'm familiarized with with multiple business requirements and operational needs. In my free time I enjoy sailing and I'm working towards obtaining a private pilot license.
