Secure API Development Expert Needed

I’m spinning up a new backend and want a hands-on developer who can jump straight into building production-ready, secure APIs. The stack is Node.js with Express, PostgreSQL on the data layer, and Microsoft Graph for several integration points. You should already be comfortable handling OAuth flows and token management because authentication is wired through Azure AD.

My priority is robustness: clean, well-documented endpoints, solid error handling, and security baked in from the start. If you have experience tightening Node.js applications against attack vectors, you’ll feel at home here.

Please tell me about projects where you built or hardened APIs on a similar stack. I’m particularly interested in how you approached authentication with Microsoft Graph or secured PostgreSQL queries.

I’m ready to get started right away and will be available for quick code reviews and feedback loops, so we can move fast and keep quality high.
