What I offer:

- SPARQL endpoint setup and custom query development

- SHACL validation rules for data quality

- RML mapping to transform CSV, JSON, or relational data into RDF triples

- Knowledge graph population and enrichment pipelines

- GraphDB, Apache Jena Fuseki, or Neo4j deployment

Perfect for:

- Research projects needing formal data models

My process:

1. We discuss your domain and data requirements
