Luís Moreira de Sousa completed the Degree on Informatics and Computers Engineering at the University of Lisbon in 2002, which he complemented with a Masters on Geographic Information Systems in 2005. In the Department of Civil Engineering of this university he was a junior researcher from 2002 to 2008, contributing to applied research projects with Instituto da Água and Estradas de Portugal. After a year as consultant with SIQuant at the National Laboratory of Civil Engineering (LNEC), in 2009 he became an independent consultant, supporting de development of the spatial data infrastructure of the newly created Administração da Região Hidrográfica do Tejo (ARH-Tejo).

In 2011 he joined the Henri Tudor institute in Luxembourg as Research Engineer, where he contributed to the development of Spatial Decision Support Systems on the domains of Energy and Urban Planning. At the time he was already a PhD candidate on Informatics Engineering at the University of Lisbon, promoted by Prof. Alberto Silva. In 2016 he concluded this graduation with a thesis on domain specific languages for the development of spatial simulation programmes. Still that year he started a post-doc position at EAWAG (Swiss Federal Institute of Research on the Water Domain) during which he conducted research on rapid flood modelling and storm water network management. Since 2017 Luís has been at ISRIC - World Soil Information in The Netherlands where he conducts research on the geography and ontology of world soils.

Luís has relied on open source software for geospatial since 2001, when he first interacted with GRASS. Since then he contributed code and documentation to various projects such as OWSLib, OpenLayers, QGis and others. In 2016 he became a OSGeo charter member and integrated the first Project Steering Committee of the PyWPS project. He was one of the founding members of the European chapter of OSGeo and chaired the Scientific Committee of the FOSS4G-Europe conference in 2018. Since 2023 Luís shares the role of Chief Returning Officer at OSGeo.
