FAQ
Which databases do you work with?
Mainly PostgreSQL, which I use every day in production. I also work with MySQL / MariaDB and Oracle.
Do I need to give you access to my database?
No. The table structure (schema) and some sample data are usually enough. You can also send a dump without sensitive data, and I will work on a copy.
Can we communicate in Spanish?
Yes, Spanish is my native language. In English I prefer written communication through the Fiverr chat.
