Profile

Senior technology leader and experienced technology architect with proven expertise in cloud-native transformations and enterprise architecture across aviation (Air France-KLM cloud transformation 2021-2026), rail (Finnish Railways sales systems migration to cloud 2016-2018), financial services/banking strategies and transformations.

Pragmatic leader, I go from portfolio and strategy to delivery: define vision/roadmaps, solutioning and architecture, lead teams (onshore, offshore) on complex projects, manage portfolios (planning/financials), and dive into technical details in cloud-native, open source technologies, as well as SAP ecosystems. I make sure that visions and strategies can be executed, and deliver them myself.

Fluent with GenAI, skilled in LLM agents and applying them to project delivery as well as consulting work to accelerate outcomes with nearly 1,000 hours saved, enhancing efficiency and quality of strategic advisory.
