FAQ
Which databases do you work with?
I primarily work with Oracle, MS SQL Server, MySQL and Postgres. If you use another SQL‑based database, please contact me first with details so I can confirm.
What do you need from me to get started?
I need a clear description of the problem, sample queries or code, information about tables involved, and (if possible) sample data or screenshots of errors. See the “Requirements” section for specifics.
Will you have direct access to my production database?
In most cases, no. I prefer working on a copy, staging environment, or sample data to keep your production data safe. If access is required, we’ll discuss safe options first.
Do you guarantee performance improvements?
I’ll always aim to improve performance and share optimization suggestions. Actual results depend on table size, indexes, hardware and other factors. I’ll explain realistic expectations before we start.
Can you help with data modeling or new database design?
Yes. For new designs or larger architecture work, please contact me before ordering so we can discuss a custom offer based on scope.
Do you write new features or only fix existing queries?
I can both fix existing queries and write new ones (reports, stored procedures, views). Just describe what you need and we’ll choose the right package or a custom offer.
Can you sign an NDA?
If your company requires an NDA, mention it in your message. We can agree on terms before starting work.
