I will write, fix, and optimise your sql queries and etl data pipelines

Are you struggling with slow SQL queries, broken ETL jobs, or a database migration that needs expert eyes?

I'm a data engineer with 5+ years of hands-on experience using SQL, Oracle, DB2, MySQL, and Talend with real project delivery at Cognizant across banking and insurance environments.

What I can do for you:

• Debug and fix broken or inefficient SQL queries
• Optimise slow queries for faster reporting and performance
• Write complex queries from scratch (joins, subqueries, stored procedures)
• Review and improve your ETL pipeline logic
• Support database migrations (DB2 Oracle and similar)
• Analyse query execution plans and explain findings in plain English

Why work with me: I don't just fix the problem I explain what caused it and how to avoid it next time. Every delivery includes clean, commented code and a plain-English summary so you actually understand what changed and why.

What I need from you: Your query or ETL logic, a brief description of the issue or goal, and the database platform you're using. That's it I'll handle the rest.

All packages include revisions. Message me before ordering if you'd like to discuss your project first.
