Back to original languageAbout David
When systems become difficult to manage, I step in to restore clear and sustainable architecture.
Data and software architect with 25 years of experience, I design and structure architectures capable of supporting growth: high-volume data modeling, distributed systems, interoperability, and data flow.
I support teams on critical topics: architecture audit, data platform design, system and flow structuring.
Short, targeted interventions or regular support.
