FAQ

MERN/PERN Applications questions.

Straight answers to what clients ask first.

MongoDB or PostgreSQL: which should I use?

It depends on your data. Structured, relational data usually suits PostgreSQL; flexible, document-shaped data can suit MongoDB. We recommend one during scoping and explain why.

Can you take over an existing MERN or PERN codebase?

Yes. We start with a code review and agree on priorities before changing anything.
