Background

About Bart Kleijngeld

Do you know what data lives in your company and where? Is it unambiguously clear what the data means everywhere it is stored or exchanged? Have you described the semantics of your data formally such that machines can make sense of it and automation can benefit from it? Is your data hard to consume because it's locked in silos? Do you have hard to maintain, opaque ETL pipelines where integration logic is tucked away and duplicated? Is your data ready to populate a knowledge graph to improve your AI solutions? If these challenges sound all too familiar and you need help tackling them: I am here to help. I am a data architect with many years of programming experience, and it is my passion to create a Linked Data world where data is findable, accessible, interoperable and reusable (FAIR). Let me help you create, maintain and make use of ontologies to formally describe your data in a machine-readable way; to make the right architectural choices to prevent bottlenecks and rigid top-down management and empower data engineers to autonomously produce their data; to seamlessly exchange and integrate data even outside of the company; to enhance collaboration between domain experts and data engineers; to build knowledge graphs so data scientists can get the most out of their LLMs. I am particularly familiar with the Semantic Web technology stack (RDF(S), OWL, SHACL, SPARQL, etc.) and LinkML for data and information modeling, and with Data Mesh for a bottom-up, decentralized architecture, but since I have a firm grasp of the underlying principles I can easily adapt to different technologies and paradigms. I also have experience writing software which transforms data models from one metamodel to another, e.g. transform a SHACL shapes graph to an Avro schema. Thanks for reading. If you think we can do something for each other or have any questions, don't hesitate to send me a message.
