About this Gig
Do you need precise data from your database but struggle with the SQL syntax?
I am a Data Science student (B.Sc. 2027) with a strong focus on databases and Python. I work with SQL and can help you extract exactly the information you need from your data structure.
I write fresh, clean, and efficient SQL queries based on the requirements and table structures you provide.
I can help you with:
- MySQL, PostgreSQL, SQL Server, SQLite
- Writing simple to complex SELECT statements.
- Connecting tables via JOINs (Inner, Left, Right).
- Aggregating data (SUM, COUNT, AVG) and Grouping.
- Creating Views or data modification queries (INSERT/UPDATE/DELETE) in the Premium package.
Why work with me?
- Academic & Professional Experience: I combine university theory with real-world practice.
- Clean Syntax: My code is readable and standard-compliant.
- Fast Delivery: I respect your time and deliver quickly.
How it works: You send me your database schema (table names, columns) and tell me what data you need (e.g., "List all users who bought item X"). I will write the SQL query for you to run.
Please contact me before ordering if you are unsure which package fits your needs!
