Alejandro Duarte is a published author and software engineer currently working for Vaadin Ltd as their Developer Relations Manager. Alejandro started to code at age 13 using the BASIC programming language on a black screen with a blinking cursor serving as the IDE. He quickly moved to C and C++—languages he still loves and enjoys—and then to Java during his computer science studies at the National University of Colombia from where he graduated. Alejandro moved to the UK and later to Finland to foster his career in the open source software industry. He became one of the well-known faces in the Vaadin and Java communities, having published articles and videos with hundreds of thousands of views in official Vaadin channels and other content portals, and presented technical topics at international Java conferences and Java User Groups. Alejandro splits his free time between his passion for the electric guitar and the photography world.
