Need help with an SQL query or database issue?

I can write, fix, debug and optimize SQL queries for existing applications and databases.

I can help with:

• SELECT, INSERT, UPDATE and DELETE queries
• JOINs, subqueries and complex filtering
• Query debugging and error fixing
• SQL performance optimization
• PostgreSQL and SQL Server
• Stored procedures
• Data transformation and aggregation

I have professional experience working with SQL databases as part of enterprise software applications, including backend development, debugging, reporting and data processing.

I focus on clear, maintainable queries and I will review the requirements before making changes.
