Apeldoorn, Gelderland, Netherlands
Azure & SQL Server DBA with 25+ years of hands-on database work, currently focused on SQL Server 2025's newest capabilities — Change Event Streaming, backup compression, and performance tuning at scale. Extensive background in data warehouse design and ETL development using SSIS, alongside deep BI experience (Analysis Services). I've worked extensively with SQL Server's AI features — vector search, DiskANN, and AI-assisted query/index tooling — building practical tooling rather than just writing about it: a live CES stream visualizer (.NET 8), a SQL Server Agent job visualizer, and AI-driven automation for index and performance analysis (sp_BlitzIndex). I write regularly about what I find — cost-based parallelism internals, migration patterns off SQL Server 2016, backup/restore strategy — over at dbaronald.com / dbaronald.nl and on GitHub. Open to freelance/consulting engagements in Azure SQL migration, performance tuning, and DBA automation.
Migrated several databases to Azure and created Azure Cost Management.
