FAQ
Can you help with my SQL assignment or project?
Yes! I can design your database, create ER diagrams, write and optimize queries (SELECT, JOIN), and implement normalization, procedures or triggers. I ensure your assignment or project is correct, efficient and on time.
Which databases and languages do you support?
I work with all major relational databases (MySQL, PostgreSQL, SQL Server, Oracle) and can integrate data with Power BI for reporting. Just share your requirements, and I’ll tailor the solution.
Do you optimize SQL queries for performance?
Absolutely. I rewrite and tune your queries (using proper JOINs, indexing, etc.), and normalize tables to improve speed. My goal is fast, reliable SQL code that runs efficiently.
