FAQ
What information do you need to optimize my SQL query?
Please provide your SQL query, table structure, relevant indexes, sample data if possible, and the current error or performance issue. If available, also share the EXPLAIN or EXPLAIN ANALYZE output.
Do you work with PostgreSQL databases?
Yes. I specialize in PostgreSQL and SQL query optimization, including query analysis, indexing, execution plans, and performance troubleshooting.
Can you fix slow SQL queries?
Yes. I can analyze slow queries, identify performance bottlenecks, review execution plans, and suggest query or index improvements.
Can you optimize complex SQL queries?
Yes. I can work with complex queries involving JOINs, subqueries, CTEs, aggregations, and multiple tables. Please contact me first for very large or complex projects.
Do you provide database design or development?
This gig focuses mainly on SQL query fixing and PostgreSQL performance optimization. Database design, development, migration, or large-scale projects may require a custom offer.
