Struggling with messy data or complex SQL queries? I can help.


I'm an SQL developer with hands-on experience in JOINs, subqueries, 

aggregate functions, stored procedures, views, and window functions. 

I work with both SQLite and MySQL.


What I can do for you:

Write and optimize SQL queries

Clean and organize messy datasets

Build custom reports from your database

Design database schemas (tables, relationships, keys)

Create stored procedures and views

Explain complex data in simple, actionable terms


Why work with me:

- Clear communication, realistic timelines

- Delivered as both runnable script + readable documentation

- Background in IT infrastructure means I understand real-world 

 systems, not just theory


Send me a message with your data/requirement I'll get back to you 

within a few hours.

I'm continuously upskilling through structured coursework in Python 

and SQL to stay current with industry practices, so you get both 

reliable results and up-to-date techniques.
