I will clean your sql database and update

I clean, fix, delete or update SQL databases to ensure your data is accurate, organised and ready for reporting. This includes correcting inconsistent records,deleting, updating tables, improving structure, writing efficient SQL queries, and preparing data for business use. I will add indexes to speed up queries, optimise existing indexes, remove unnecessary indexes, improve JOIN performance and reduce full table scans.I work across Microsoft SQL Server, PostgreSQL, MariaDB and SQLite, delivering reliable data that supports operations, monthly reporting and workflow improvements.
