    I have dedicated my career to Geographic Information Systems and data, doing web apps with maps, geospatial APIs and plugins. On the back-end, I have been using Python and Django since 2016, and on the front-end I have been using VueJS since 2020. I'm also proficient with HTML5, CSS/SASS, vanilla ES6 and Docker. I like paying attention to UX/UI details and I often use Quasar when working with VueJS. On web mapping JS frameworks, I'm most experienced with Leaflet, but I have worked with Google Maps, Open Layers, Cesium JS and Mapbox GL JS. I have also experience with GeoServer, PostGIS and other standard spatial libraries such as Geopandas, Fiona, Shapely and GDAL. I have also done a couple of plugins for QGIS. I have worked as a teacher and training content writer on-and-off at the University of Girona and in some freelancing jobs here at Upwork. Besides IT training companies, as a freelancer I have also worked in long-term jobs with IoT (smart cities, indoor positioning) and retail analytics companies.
