What I'm looking for

I'm looking for remote freelance or contract work building reliable AI-integrated .NET systems, where architecture, observability, data integrity, performance, and engineering governance matter at production scale.

At LEGO, I'm helping re-platform the 20-year-old BrickLink marketplace on AWS, including a redesigned feedback API and reusable middleware adopted across the team. As test champion, I introduced weekly automated performance regression testing, architecture tests, and a team test strategy.

Previously at Medidata, I led the Europe team for an FDA-regulated clinical-data streaming platform. I built self-service data publishing, owned Flink and Iceberg compaction that reduced five production tables from roughly 8 billion to 300 million rows, and supported production data incidents across AWS pipelines.

I've also delivered multi-tenant HR platform features at Pentalog and owned systems for a Dutch retail client at Duk-Tech, including a warehouse scanning app credited with reducing logistics overhead by roughly 40%. I'm now applying my .NET architecture, reliability, and governance discipline to AI-integrated systems through Claude-assisted workflows and MCP connectors.
