Hi there, From your description, this looks like the kind of backend / API builds where a confident closer-style approach actually matters. Here’s how I’d approach it: With JavaScript, Web Security, Penetration Testing in your stack, I’ll keep the structure lightweight, predictable and easy to maintain. • Structure configuration and environment variables so deployment is clean and repeatable. • Keep the database layer simple and consistent so queries stay fast and debugging is painless. Happy to start with a focused first milestone so you have something concrete to review quickly. If this feels aligned with what you’re aiming for, I’d be glad to take this forward. Best regards, Duncan.
