About Daniel

Ex-Director of Software Engineering in digital banking with over 15 years of experience scaling secure architectures and leading cross-functional engineering teams.
Specialized in strategic intelligence, IT governance, and high-availability systems.

I bridge the gap between business strategy and complex technical execution. My expertise covers enterprise cloud architecture (AWS), robust data governance, information security, and AI infrastructure implementation. I have a proven track record of managing large-scale software engineering departments and designing risk mitigation frameworks for highly regulated environments.

Available across the EU for fractional advisory (10-20 hours/week), thorough technical architecture audits, and discrete interim leadership mandates during critical scaling or transition phases.
