Van Thoai Nguyen has worked in the software industry for a decade in various domains. In 2012, he joined BuzzNumbers as one of the core senior software engineers, where he had opportunities to design, implement, and apply many cool technologies, tools, and frameworks. A RabbitMQ cluster was employed as the backbone of the real-time data processing platform, which includes various data collectors, data filtering, enrichment, and storage using a sharded cluster of MongoDB and SOLR. He is still maintaining the open source .NET RabbitMQ client library, Burrow.NET (https://github.com/vanthoainguyen/Burrow.NET), which he built during the time he worked for BuzzNumbers. This library is still being used in many different applications in that company. Van is interested in clean code and design, SOLID principle, and BIG data.

Héctor Veiga is a software engineer specializing in real-time data integration and processing. Recently, he has focused his work on different cloud technologies, such as AWS, to develop scalable, resilient, and high-performing applications with the latest open source technologies, such as Scala, Akka, or Apache Spark. Additionally, he has a strong foundation in messaging systems, such as RabbitMQ and AMQP. He also has a master's degree in telecommunications engineering from the Universidad Politécnica de Madrid and a master's degree in information technology and management from the Illinois Institute of Technology.

He currently works as part of the Connected Driving real-time data collection team and is actively developing scalable applications to ingest and process data from several different sources. He utilizes RabbitMQ heavily to address their messaging requirements. In the past, he worked at Xaptum Technologies, a company dedicated to M2M technologies.

Héctor also helped with the reviewing process of RabbitMQ Cookbook and RabbitMQ Essentials, both from Packt Publishing.

I would like to thank my parents, Pilar and Jose Carlos, as well as my sister, Paula, for always supporting me and motivating me to keep pushing on. Without them, all this would not have been possible.
