About this Gig
Slow queries? Broken schema? A report you can't get the data out of?
I've spent 5+ years working hands-on with relational databases, and I fix the boring problems that quietly break products: queries that scan entire tables, missing indexes, tangled schemas, and CPU spikes nobody can explain.
Engines I work with
MySQL · MariaDB · PostgreSQL · Oracle · SQL Server · SQLite · MS Access
What I can do
Write and debug queries, joins, and stored procedures
Find and fix slow queries and high CPU usage
Design or restructure schemas (normalized, with an ERD)
Add the right indexes and remove the ones costing you writes
Set up backups and a recovery plan
Migrate or import data between databases and between engines
How I work
You send me access or a dump file and tell me what's wrong in plain language. I diagnose it, fix it, and explain what I changed so you're not dependent on me next time.
Not sure which engine you're even on? Send me a screenshot I'll tell you.
