Hi, I’m Camilo

Senior Solutions Architect for Cloud, Data & AI

I design the semantic layer behind enterprise data platforms, present it to stakeholders, and deploy it myself — primarily on Azure, for organizations where data is operationally critical.

About

Eight years designing cloud-native data and AI platforms, primarily on Azure, for enterprise organizations.

At Bosch I’m technical lead for the enterprise knowledge graph — the master data platform serving around 3,500 people a day across every division. I model the ontology estate in TopBraid EDG using RDF, OWL and SHACL under federated data mesh governance, and automated the pipeline behind it on Databricks. On a separate engagement I delivered €778K in Azure savings in one year.

I move between whiteboard and terminal: modelling the ontology, presenting the architecture to stakeholders, and shipping it myself.
