Write to me about a database problem, to ask for an assessment, or just to ask a question. The fastest route is booking a slot straight from my calendar.

Include these and the first answer will actually be useful

Without the details below, any answer is a guess. If you do not have all of them, send what you have. If you have none of them, write anyway and we will work out where to look.

  • Version and build number. For SQL Server the output of SELECT @@VERSION is enough.
  • When the problem started and whether anything in the environment changed around then. That single line often halves the search.
  • Whether the server is physical, virtual or in the cloud. Core count and memory help too.
  • A rough idea of database size and daily transaction volume.
  • Wait statistics if you have them, or the execution plan of the slow query.

What I work on

Performance tuning, high availability with Always On, Azure and hybrid data setups, and SQL Server 2025 migration assessments. The scope, how a project runs and what access I need are described on the Consulting page.
