MySQL Developer for Hire
WordPress database work done properly - query optimization, bloat cleanup, migration, error diagnosis, and direct SQL when WP_Query is not enough.
What is MySQL?
What is MySQL and what can it do?
MySQL is the relational database management system that stores every piece of WordPress content - posts, pages, users, options, meta, comments, and WooCommerce orders all live in MySQL tables. Every time WordPress renders a page, it queries MySQL to fetch the content. When the database is slow, bloated, or misconfigured, the entire site slows down regardless of caching or CDN.
In the WordPress context, MySQL work covers several distinct areas: direct database queries using for operations that WP_Query cannot handle efficiently, database optimization by removing post revisions, expired transients, orphaned postmeta, and auto-draft accumulation, safe search-and-replace operations on the database during migrations and URL changes, diagnosing slow queries using MySQL slow query log and EXPLAIN, and recovering data from backups after a corrupted or accidentally deleted table.
I work with MySQL as a standard part of WordPress development and maintenance. I use WP-CLI and phpMyAdmin for database operations, write queries following WordPress security standards, and always work on a database backup before running any direct SQL on a live site. Database work done carelessly destroys sites - done carefully, it is one of the highest-impact things you can do for performance.
Available worldwide. Available to clients in the US, UK, Australia, Canada, and Europe for WordPress database work, migrations, and performance optimization. All work delivered remotely with async communication, full project documentation, and timezone-overlap scheduling for live calls.
What I Do with MySQL
Five-plus years of hands-on MySQL work across 100+ client projects worldwide. Here's the depth I bring to your build.
- $wpdb for direct WordPress database queries with proper sanitization and prepared statements
- WordPress database optimization - post revisions, auto-drafts, transients, orphaned meta, and spam comments
- Safe search-and-replace on serialized data during site migrations using WP-CLI or Better Search Replace
- WP_Query optimization - posts_per_page limits, fields => ids, no_found_rows, and transient caching
- MySQL slow query diagnosis using EXPLAIN and slow query log analysis
- WooCommerce database maintenance - cleaning orphaned order meta and optimizing product query tables
- Database error diagnosis - Error establishing a database connection, table lock errors, and connection limit issues
- Site migration database handling - export, import, URL replacement, and prefix changes via phpMyAdmin and WP-CLI
- Object cache configuration with Redis or Memcached to reduce repetitive MySQL queries
- Database backup and recovery using WP-CLI, mysqldump, and hosting control panel tools

The WordPress database is the one place where a mistake is immediately and seriously destructive. A wrong UPDATE query with no WHERE clause overwrites every row in a table. A search-and-replace on serialized data using a basic text replacement breaks every serialized array in the database. A truncated import leaves the site in a half-migrated state that is harder to recover from than starting over.
Every piece of database work I do starts with a verified backup. Not a backup I assume exists - a backup I have confirmed is complete and restorable before touching the first query. Search-and-replace operations are always done with WP-CLI or Better Search Replace, never with a raw SQL REPLACE() statement, because serialized data requires length recalculation that plain SQL does not perform.
If you have a database problem - slow site, migration issue, corrupted table, or an error you cannot diagnose - the most important thing is not to run random SQL fixes found in a forum thread. Contact me, describe the symptom, and I will tell you exactly what the cause is before suggesting any fix.

I communicate clearly, meet deadlines, and do not disappear mid-project. If something does not work as expected, I fix it. That is why my Upwork score has stayed at 100% across 100+ projects.
