Authorisation, databases, APIs, secrets, payments, AI boundaries, monitoring and backups the practical security checks before an MVP meets real customers.

Your MVP works and customers are paying. Before you scale acquisition, ask what you're actually scaling — because fragile architecture turns growth into exposure.

AI can generate the feature. Someone still owns the architecture, the security and the release. The new engineering roles emerging and the skills that now decide outcomes.

Cursor, Lovable, Bolt.new, v0, Claude Code, Replit Agent, Base44, Windsurf, Devin and Rork — what each one actually does, and where real engineering still begins.

When you can build so quickly and so affordably, it is incredibly tempting to dive straight into the code before you have really heard from the people you are trying to help.
