Automated the process chain to transform remote sensing data in vector formats for agriculture machinery, thus saving many hours of manual processing. Completed on behalf of the Polish startup, Satagro.

Explored the possibilities of adding holes in the Leaflet polygon edition tool.

Developed a web application for the Swiss Association for the Promotion of Swiss Bench Culture (Bankgeheimnisse.ch/map). It documented benches in Switzerland which has now around 12,000 benches and 600 users.

Implemented, for the above project, the services as a REST API. deployed the application in AWS, and implemented monitoring with Grafana.

Developed a real-time map of public transport speed in Pays de Gex/Geneva showing the current status, past data, and prediction of the next 24 hours. It's no longer online.

Created a data-gathering service consuming the Geneva public transport company APIs 24/7.

Extracted public transport service routes and stops from OpenStreetMap.

Performed a data analysis and modeling of the public transport data with R.

Implemented a web page showing the status of the line and 24 hours worth of predictions.

Data Analyst | Full-stack Developer | GIS Developer

Developed a web application to publish different countries' national forest data.

Built process chains to prepare the forest data (raster and vector), resulting in a semi-automatic publication of the data.

Deployed the application in Argentina, Paraguay, and Ecuador in collaboration with local technicians.

Developed PL/pgSQL scripts in order to compute the total surfaces of the different forest classification classes.

Geospatial Software Engineer

Developed an Android client for Ikimap (a map repository where users can vote and comment maps).

Contributed to the gvSIG Android version to allow new user interactions with the map control and to improve drawing speed of big vector layers, making it possible to base the development of the Ikimap's Android client on it.

Built a web tool to plan geotechnical surveys (http://five.es/geoweb/).

Constructed a GIS data repository to be used as a source for reproducible experiments for the Mediterranean Center for Marine and Environmental Research (CMIMA).

Migrated different types of data sources to NetCDF format and loaded as NetCDF in the CMIMA repository.

Wrote an algorithm to calculate the radiation and visibility in 3D urban environments.

Developed a geoprocessing specific language allowing users to create complex chains to processing spatial information, regardless of the data storage (database, file, web service) or format (shapefile, GML, PostGIS, TIFF, JPEG, and so on).

Built gvSIG extensions to analyze radar data, support land surveying processes, cadastral management, and so on.

Developed a tool to implement image quality control for the National Plan for Aerial Orthophotography in Extremadura, Spain.

Full-stack Developer | GIS Developer

Developed OrbisGIS, a desktop GIS application providing a spatial SQL engine implementation which allows researchers to manipulate their spatial data (raster, vector, databases, files, web services, and more) in a transparent way.

Designed and implemented the data abstraction layer for different file formats and database vendors of both raster and vector data.

Constructed the OrbisGIS SQL engine on top of the data abstraction layer.

Developed a disk-based R-tree implementation for the indexation of spatial data sources.

Research Engineer

Developed a desktop application for the management of pasture use in Castilla la Mancha.
Supported the development of gvSIG extensions.

Developed the core of gvSIG, open source desktop GIS application.
Created a dynamic map for the Valencian tourist agency's web page, showing resources of interest for tourists.

GIS Developer

I have developed in Java for 15 years. Whenever I have been doing backend projects I have used Spring and so I have experience with data, security, JWT authentication, etc. These projects include both monoliths and microservice architectures and I am enthusiastic about the resilience advantages and challenges of the later.

As a developer I am used to TDD practices and I like to have in mind the ROI of testing, in order to produce the right amount of unit, functional, e2e, UI, etc. I have an extensive experience in testing and I know the risks it involves (maintenance costs, slow tests suites, etc.) and the benefits of continuous integration practices.

I have done Geographical Information Systems (GIS) for 15 years and I have used spatial databases, map servers and geospatial libraries. I understand different geometric models (Simple Features Specification, OSM), raster formats, tile caching, vector tiling, etc. And I am used to the challenges that big two-dimensional (at least) geo-data introduces.

I am proud of having contributed with bug fixes to GeoServer and GeoTools, two major projects in the FOSS GIS ecosystem:
- https://osgeo-org.atlassian.net/browse/GEOS-7243
- https://osgeo-org.atlassian.net/browse/GEOT-3759

I like to know exactly what is going on in production. I love dashboards showing response time, cpu and memory usage, etc. And alerting me of any misbehavior on any part of the system.

I have been using docker for deploying both monoliths and microservices solutions, manually with compose, with swarm on a set of hosts or in AWS.

As a GIS specialist I have worked extensively with PostgreSQL (because of its spatial extension PostGIS). I have been involved in tweaking server parameters for optimization, analyzing queries execution plan and developing complex analysis processes in pl/pgsql. On a higher level, I have a deep knowledge of JPA and the nuances of the different approaches to represent the data relations, just as of the JPQL language itself.

I am in love with ReactJS. I have done frontend work since a long time and I have gone through a lot: applets, ajax queries submiting a hidden form, Google Web Toolkit, jQuery and some "I'll never use a framework again". And finally ReactJS, which allows to reuse components in a very easy way.

I try to run away from the Javascript "framework speed dating" culture and I try to stick to the technologies I use and keep my developments as close as possible to the base of Javascript, HTML and CSS, which I know well.

I have seen things you would not believe. Ajax requests with hidden frames. I watched terabytes of images served from a external USB disk. All those moments will be lost in time (I hope).
