Andrea Gazzarini is a curious software engineer, mainly focused on the Java technology. He strongly loves coding and definitely likes to be considered a developer. Andrea has more than 20 years of experience in various software engineering areas, from telecommunications to banking. He has worked for several medium- and large-scale companies, such as IBM and Orga Systems. Andrea has several certifications in the Java programming language (programmer, developer, web component developer, business component developer, and JEE architect), BEA products (build and portal solutions), and Apache Solr (Lucid Apache Solr/Lucene Certified Developer). In 2009, Andrea stepped into the wonderful world of open source projects, and in the same year, he became a committer for the Apache Qpid project. His adventure with the search domain began in 2010, when he met Apache Solr and, later, Elasticsearch….and it was love at first sight. Since then, he has been involved as a Search Engineer in many projects ranging in different fields (bibliographic, e-government, e-commerce, geospatial). In 2015 he wrote “Apache Solr Essentials”, published by Packt Publishing. Andrea is an open-source lover, he is currently involved in several (too many!) projects, always thinking about a “big” idea that will change his (developer) life.
