01 / Narrative
Data functions, platforms, data quality and governance.
His work sits where commercial performance, regulatory control, and executive decision quality meet: building data functions, modernising platforms, improving data quality, and creating governance that gives senior leaders confidence in the numbers.
He combines board-level credibility with hands-on technical fluency in Python, SQL, cloud data platforms, applied AI, RAG patterns, knowledge graphs, and agentic systems. That mix matters because the hardest executive data decisions are rarely solved by a platform selection alone.
He has held four Head of Data roles: Alpha Bank London, Volante Global, MTC UK and HSBC.
