Xavier in a few words
I have Spanish and British citizenship. I am a curious person who looks forward to learning things every day. I am really passionate about technology, teaching, and coaching. I am the author of two Java manuals. I love teaching students and coaching people. I do really like to interact with groups to contribute to my ideas.

Related to technology, my main fields of interest are Java, Big Data, Computer Science, Project Management, and Coaching.

I obtained my postgraduate in Big Data Management and Analytics, Big Data and Data Science from the UPC School of Professional & Executive Development in 2016 and my B.S. in Audiovisual Systems Engineering(Telecommunication degree) from Universitat Politècnica de Catalunya in 2015, after completing my thesis on Object tracking using real-world coordinates at Institut für Nachrichtenübertragung in Technische Universität Berlin.

Xavier es un profesional muy cualificado y proactivo. Me realizó la creación de un website y contrario a otros freelance con los que he trabajo, Xavier participó activamente en el proyecto y estuvo pendiente de gestionar todas las demandas y necesidades que teníamos para la website. Además de la programación se encargó activamente en el diseño y estética de la web, agradecemos mucho su implicación y el resultado final. Gran profesional y súper recomendable, repetiremos otros proyectos con él seguro!

  • Bachelor thesis
    Technische Universität Berlin
    2015
    Title of the project: Object Tracking with multiple cameras using real world coordinates. Abstract: This thesis covers the design and implementation of a Gaussian Mixture Probability Hypothesis Density Filter. A new approach is used on this filter, instead of using the object detections in pixel coordinates, a camera system is attached to this filter in order to treat the detections of all objects in real world coordinates. The thesis is intended to be an enhancement of the typical GM-PHD Filter. The system is able to work in an scenario with multiple views and also shows a top image view generated from all the views. This new approach allows using multiple detectors, reducing the probability the missed detections. The results are subjectively better using one detector in world mode but using more detectors some noise is produced by the camera system affecting negatively to the system.
