About this Gig
our application is only as reliable as the database underneath it. I design clean, normalized MySQL schemas from scratch, or step in to fix databases left behind by a previous developer duplicate tables, missing foreign keys, no indexes, inconsistent data types, the works.
With over 10 years building production PHP/MySQL systems (hospital management, diagnostic lab portals, recruitment platforms, library systems, payment and billing modules), I know what a schema needs to hold up under real usage: proper normalization (up to 3NF where it makes sense), correct relationships and constraints, indexing for the queries you'll actually run, and a structure your developers can extend without fighting it.
If you're migrating from a spreadsheet, rescuing a project after a bad freelancer experience, or just need a second pair of eyes on your current structure before you scale, that's exactly what this gig covers.

FAQ
Can you fix a database that's already corrupted or has bad data in it?
Yes — auditing and repairing existing databases, including ones left in a messy state by a previous developer, is exactly what the Basic and Standard packages are built for.
Do you provide an ER diagram?
Yes, included from the Standard package up. It's part of how I make sure you understand the structure before it goes into production
What do you need from me to get started?
Ideally a description of what your application does, a list of the data you need to store, and — if you have one — an export of your current database or spreadsheet.
Can this integrate with my existing PHP/Node/whatever backend?
The schema itself is backend-agnostic, but if you want help wiring it into PHP specifically, that's the Premium package or the PDO integration add-on.
Do you only work with MySQL?
MySQL/MariaDB is my core specialty, which is what this gig is scoped around — it's where I can guarantee the deepest expertise.
