Senior🎓
Top SchoolCarlos Alonso is a data engineer and DHIS2 specialist with 15 years' experience designing health information systems, metadata standards, and data integration pipelines for global health and ICT4D projects. Based in Madrid, he leads DHIS2 metadata quality assurance at the University of Oslo while consulting on implementations, migrations and interoperability across FHIR, ICD, SNOMED, LOINC and other clinical vocabularies. He combines strong software engineering (Python, Java, ETL, APIs) and Semantic Web expertise (RDF, SPARQL, SKOS, SHACL) with practical work producing Linked Open Data, controlled vocabularies and PowerBI integration for DHIS2. A seasoned trainer and multicultural collaborator, he has delivered capacity-building and technical support across Africa, Asia and Latin America for organizations including MSF, PAHO and PSI. He is also an active open-source contributor (e.g., improvements and tests to the widely used SPARQLWrapper library), bridging academic research, standards work and production deployments. Carlos’s background in both research and hands-on implementation gives him a rare ability to turn complex metadata and standards requirements into robust, usable health data systems.
