I will optimize your slow postgresql queries and fix performance issues
About this Gig
Is your PostgreSQL query taking 30 seconds when it should take less? I'll find out exactly why - and fix it.
WHAT I CHECK
Every query gets the same systematic review: execution plan, scan types, index usage, join behaviour, statistics accuracy - and whether the bottleneck is even in the query at all. Sometimes it's table bloat, locks or configuration.
Most slow queries come down to a handful of cases. Finding which one takes reading the plan, not guessing.
11 years with PostgreSQL, mostly on government, healthcare and banking systems - where reports run against millions of rows and "a bit slow" isn't an acceptable answer.
WHAT YOU GET
- The optimized query, ready to use
- EXPLAIN ANALYZE before and after, so you can verify
- Index statements to run, if needed
- A written explanation of what was wrong, in plain language
WHAT I NEED
Your query, the EXPLAIN (ANALYZE, BUFFERS) output, your table definitions and existing indexes. No database access, no production data.
NOT SURE?
Message me the query and the plan before ordering. I'll tell you honestly whether it can be improved.

FAQ
Do you need access to my database?
No, I work from your query, the execution plan and your schema definitions. No credentials, no production data.
What if my query can't be optimized?
Then I'll tell you, and explain where the real bottleneck is - often it's the schema, missing indexes elsewhere, table bload or server configuration rather than the query itself. You'll still get a diagnosis and a recommendation
I don't know how to run EXPLAIN ANALYZE
Message me first. It's one line, and I'll show you exactly what to run
Will you explain what you changed?
Always. Every delivery includes a written explanation of the cause and the fix
What if the numbers my query returns are wrong, not just slow?
That's also something I handle - usually it's row multiplication from joins or NULL handling. Mention it when you order
