How I Work Today

I work with companies that need senior database expertise without necessarily building a large internal DBA team.

This can range from several hours of consulting or regular external DBA coverage to complex migrations, architecture projects and critical production troubleshooting.

Reliable databases are not just about technology. They are about understanding the environment before something goes wrong.
