Profile
Senior engineer with 15+ years of experience integrating systems, since 2019 designing, building and operating business-critical distributed systems in regulated environments.
Two things that rarely sit in one CV: the engineering that moves data, and the research that questions it. On one side, integration and data platforms, reconciling systems that disagree about the same entity and building the pipelines that carry the result. On the other, formal quantitative research conducted at Philips Research and published: study design, standardised instruments, significance testing.
Combines that with a strong focus on reliability, observability and operational excellence, and on enabling development teams through standardisation and CI/CD practices.
Known for reducing system complexity, increasing reliability, and acting as an escalation point for production-critical systems in high-volume environments.
Focused on designing and operating reliable integration and data components in cloud environments, and on the analysis that decides what they should carry.
