Veelgestelde vragen
Do you work with NoSQL databases like MongoDB, or only SQL?
Yes, I work with both SQL (MySQL, SQL Server, Azure SQL) and NoSQL (MongoDB and similar) databases. Let me know your platform and I'll confirm scope before we start.
What if my query is more complex than the package limit?
No problem — message me with your requirements and I'll provide a custom quote for the extra scope.
Do you need direct access to my database?
Not necessarily — in most cases, you can share your schema, sample data, or connection details securely, and I can also work with a test/staging environment if you prefer not to share production access.
How many revisions are included?
Basic includes 2 revisions, Standard includes 3, and Premium includes unlimited revisions.
Can you fix or optimize queries I've already written, not just write new ones?
Yes — debugging and optimizing existing queries is included from the Standard package upward.
