2) Developing services based on collected data to customise user's experience

3) Deployment and maintenance of data and backend services

Skills: ELK, Kafka, Hadoop HDFS, Apache Spark, Cassandra, Couchbase, Docker, Kubernetes, Scala, Bash

PhD Research & Development Internship

05/2015 - 08/2015

Internship in Machine Learning focusing on a very particular issue called 'cold-start': situation in which new users (or items) are new in the system; therefore there is no information about them leading in a miss classification.

Active Learning has been proposed to face cold start by intelligently acquire the needed essential data from very first users.

Skills: Hadoop MapReduce, Java, Machine Learning

Ph.D Research & Development / Project Manager

10/2013 - 09/2016

Thesis oriented to industry: Thesis dubbed Towards Accurate and Scalable Recommender Systems

The enormous quantity of information in Webs may overwhelm users. Recommender Systems study the interest of users in order to pre-select information in which he/she might be more interested. My goal in this subject is to create a recommender system that relies on two concepts: generic implicit relations in data and distributed collaborative filtering techniques.

Skills: Hadoop MapReduce, Apache Mahout, Java, R-Cran, SQL, Bloom Filters, Weka, Protegee, Jena, SPARQL

Extra: Project Manager for final master projects focused on recommender systems
