The biggest Java conference in Central America, Jconf Guatemala, was held on November 8th and 9th, 2019 by the Guatemala Java User Group –GuateJUG-. The conference, formerly known as Java Day Guatemala, gathered more than three hundred attendees from different countries like Mexico, Guatemala, El Salvador, Costa Rica, Perú, Colombia, Ecuador, and Honduras. The conference had a broad participation from local speakers along with various Java Champions, Ground Breakers, and developers advocates from the Industry.

JConf is an effort promoted by various Latin America Java User Groups to homogenise the yearly conferences organized in countries like Perú, Colombia, Domincan Republic, Ecuador and Guatemala. JConf Guatemala started on November 8th with an unconference and reception event.

This year I participated along with José Díaz from Perú delivering the workshop “Developing Java based microservices with Eclipse MicroProfile”. The use cases presented by José, and his experience with enterprise software architectures, provided a value added for the attendees along with the latest and greatest Eclipse MicroProfile and Apache TomEE tips and tricks we shared to speed up the development of cloud-native microservices.

I want to thank the vibrant Guatemala Java user group for the organization of this event that over the past nine years keeps growing at a steady pace and provides a hub for Central and Latin America IT communities to gather, learn, and share.
