Back to original languageAbout Harold
After nearly 6 years in a successful startup, I want to refocus my activity on technical expertise. I am inspired by the principles of Joe Reis and Matt Housley, convinced that the foundations of a robust data stack rest on communication, governance, and a clear definition of roles. I particularly appreciate Data Mesh architectures and Modern Data Stack technologies for building reliable and scalable pipelines.
