I will write, fix, or optimize sql queries for your database

Hi, I'm Mohamad, a Computer Engineering graduate with solid knowledge of SQL and relational database design.

I can help you with:

• Writing SQL queries (SELECT, JOIN, GROUP BY, subqueries)
• Fixing broken or incorrect queries
• Basic query optimization (improving slow or inefficient queries)
• Explaining what a query does and why

I work with MySQL and PostgreSQL. If your task is different or you're not sure I'm the right fit, message me first and I'll tell you honestly I'd rather be upfront than take on something I can't deliver well.

I double-check every query before delivery to make sure it actually works and matches what you asked for.

Looking forward to helping with your database!
