FAQ
Should I contact you before placing an order?
Yes. For larger databases, production systems or complex performance issues, please contact me first so I can review the scope and recommend the correct package.
Which databases do you work with?
I primarily work with PostgreSQL, Supabase PostgreSQL and SQL Server, and I can also help with general SQL query optimisation and database logic.
Can you optimise slow SQL queries?
Yes. I can review execution plans, joins, filters, indexes, aggregations and query structure to identify performance bottlenecks.
Can you work with Supabase?
Yes. I can help optimise Supabase PostgreSQL queries, functions, views, indexes and database logic.
Do you need access to my production database?
Not always. In many cases, SQL scripts, schema details, sample/anonymised data and EXPLAIN ANALYZE output are enough. If live access is required, read-only access is preferred where possible.
Can you fix stored procedures, functions and views?
Yes. I can troubleshoot, refactor and optimise database functions, stored procedures and views.
Will you explain what was changed?
Yes. Where appropriate, I will explain the cause of the issue and the changes made so the solution is understandable and maintainable.
