FAQ
1. What information do you need before starting an optimization task?
To optimize your SQL queries effectively, I will ideally need the table DDLs, current indexes, volume of data, and the execution plan or query output if available. If you don't know how to extract these, I can guide you through it.
2. How do you handle 1-on-1 learning or live troubleshooting sessions?
We can conduct live sessions using Zoom or Google Meet (via Fiverr’s approved communication tools). You can share your screen, and I will guide you step-by-step through the concepts, debugging, or project logic.
3. Will my database data remain secure and confidential?
Absolutely. Security is a priority. I highly recommend providing obfuscated, dummy, or masked data for development/testing purposes. I will never ask for or store sensitive production credentials.
4. Can you work on DB2 for both LUW (Linux, Unix, Windows) and z/OS Mainframe?
Only DB2 for LUW
