About this Gig

Your queries used to be fast. Now they're not, and you're not sure why.


I diagnose slow SQL execution plans, missing indexes, non-sargable

filters and deliver a tested, rewritten fix with a plain explanation

of what was wrong and why the rewrite works. Not a guess: every fix is

verified to return the exact same results as the original, just faster.


20+ years of hands-on SQL Server experience in a commercial bank's

payment operations, where a query that timed out wasn't an inconvenience

it was a real problem. That same discipline applies here.


What's in scope: query troubleshooting, execution plan review, indexing

recommendations, and rewrites from your schema or sample data, no live

database access required.


What's not in scope: live production database access, new infrastructure

setup, or hosting/administration of a database platform. If that's what

you need, this isn't the right gig happy to say so upfront rather than

take it on and figure it out on your dime.


Send your slow query and a description of the schema (or a sample of your

data) and I'll tell you exactly what's happening before you commit to a

tier.
