My current interests are in the area of research, Cloud Computing and BigData. I use technologies like Hadoop, Spark, AWS, Hive, the Scala programming language, Java, Python, the Scalding library, Cassandra, MongoDB, RabbitMQ and R on a daily basis. I am the author of the Scala Design Patterns book (ISBN 13: 9781785882500, URL: https://www.packtpub.com/application-development/scala-design-patterns), published by Packt Publishing. The expected release date is March 2016.

Specialties: programming, software development, engineering, design, databases, BigData, research, design patterns, c, c++, c#, java, scala, asp.net, html, css, javascript, jquery, ajax, machine learning, mapreduce, hadoop, spark, python, entity framework, security, xml, web services, streaming, postgresql, parallel programming, cloud computing

Senior Software Engineer @ I work as a senior software engineer at Adthena. As a member of a small team my role spreads around multiple different technologies that cover quite a big stack. I work on the back end, front end, architecture and system administration. Some of the most used technologies are: Back end: Java and Scala, as well as some Python and bash scripting. I use Spark, Cassandra, MongoDB, PostgreSQL, MS SQL Server, RabbitMQ and Storm on a daily basis. Front end: RequireJS, NodeJS, Backbone and many others. System administration: we deal with our infrastructure ourselves and I use Ansible to manage and provision hundreds of machines on AWS, including starting and terminating short-lived instances, etc. From May 2015 to Present (8 months) London, United KingdomSenior Big Data Software Engineer @ Currently a Senior Software Engineer in the Predictive Analytics (R&D) team. My work includes using technologies (on a daily basis) like Hadoop, Scalding, Cassandra, Spark, HBase, R, Kafka and the Scala Programming Language for data analytics, aggregation, algorithms, real-time and Machine Learning applications. From November 2014 to May 2015 (7 months) London, United KingdomBig Data Software Engineer @ First I started as a back end engineer for applications written with GWT and JSP. Then I took part in developing and then extending one of the core company products (WHYanalytics and the whole WHYsuite) again as a back end engineer using Java server technologies (mainly Jersey and a little bit of Spring). Then I joined the R&D team where I work as a big data software engineer on tasks related to data analytics, aggregation and algorithms development. The main technologies I use there are Hadoop, Cassandra, Spark, the Scala programming language, Scalding and R.
