Hire a Database Developer
The layer where mistakes are permanent: schemas designed for the queries they serve, migrations that never stop the business, restores that are tested.
Every application failure mode eventually bottoms out in the database: the schema that cannot answer the question the business asks, the query that was fine at 10k rows and is fatal at 10 million, the migration that takes the site down for an afternoon. Database work is where discipline pays the highest interest — because it is the layer where changes are hardest to undo and mistakes are visible to everyone.
Typical engagements: schema design for new applications (PostgreSQL and MySQL), query performance rescue on slow production systems, zero-downtime migration planning for live products, data modeling for reporting and analytics, and backup/recovery architecture — including the restore drills everyone intends to do and nobody does.

Questions
Asked about Databases.
Both are excellent and production-proven at any scale. PostgreSQL for richer data types, stricter semantics and analytical-adjacent work; MySQL where the ecosystem and hosting default to it. The choice matters far less than the schema discipline on top — spend your concern there.
Usually — slow production databases are overwhelmingly missing indexes, N+1 query patterns from the application layer, and unbounded reports. A profiling pass finds them; the fixes are typically surgical. Where rearchitecture is genuinely needed, you see the evidence and the staged plan before anything touches production.
Yes — the discipline is in the parts nobody sees: field mapping documents, transformation rules, reconciliation counts on both sides, dry runs on copies, and a rollback position. Data arrives with receipts, or it does not ship.
