Veelgestelde vragen
What do you need from me to get started?
Please share a brief description of the issue, any error messages, and the query or code if available. If needed, I may request temporary access (connection, backup, or remote access) to diagnose and resolve the issue quickly.
Is my data safe with you?
Yes — I handle all client data with strict confidentiality. I only access what is necessary to resolve the issue. NDA is available upon request, and you may provide sanitized or restricted access if preferred.
What if I don’t know what the problem is?
That’s completely fine. Just describe the symptoms (errors, slow queries, timeouts), and I will identify the root cause and recommend the best solution.
Can you work with large or production databases?
Yes. I regularly work with large, production SQL Server environments and apply fixes carefully to avoid downtime while ensuring stable, reliable performance improvements.
Do you support all SQL Server versions?
Yes — I support most SQL Server versions (2008–2022) across Express, Standard, and Enterprise editions. If unsure, feel free to ask.
What if the issue requires more work than the package I selected?
If the issue is more complex than expected, I will explain the scope clearly and provide a custom quote or recommend the right package before any work begins. No surprises.
Can you optimize my entire database, not just one query?
Yes. I offer full database optimization including indexing, execution plans, and overall performance tuning. Premium is designed for complete database improvements.
Do you offer ongoing support or maintenance?
Yes. I offer ongoing support including monitoring, performance optimization, and DBA assistance, with custom plans tailored to your system and requirements.
