What I'm looking for

I seek roles where I can lead knowledge-graph and metadata strategy, integrate LLMs with structured data, mentor teams, and deliver FAIR, production-ready data solutions.

I am a knowledge-graph and data engineering lead with deep experience in linked open data, metadata design, and integrating semantics with large language models to enable robust data-driven products.

At Almawave I lead knowledge engineering activities, designing dataset metadata, versioning, preprocessing pipelines, and prototyping virtual knowledge graphs to map ML processes, datasets and provenance; I champion FAIR principles and have contributed to multiple open data and semantic web projects for public organizations.

I work as a freelancer and consultant on greenfield projects, technical writing, teaching and prototyping POCs, bringing practical experience across RDF/OWL, SPARQL, Python, Scala/Java, Hugging Face, Elasticsearch, DuckDB, lakeFS and containerized deployments.
