USA Portal Appointment Scheduler

I need a production-ready software extension that plugs into a leading U.S. web portal and lets authenticated users reserve time slots. The core feature is straightforward—secure appointment booking—but I still expect a polished flow: user login, calendar view, slot validation against my internal rules, and a clean confirmation page.

Because my previous developer left mid-stream, I’m only interested in someone who has built a similar portal integration before and can prove it with a demo or code sample. You’ll be inheriting some partial work, so quick comprehension and the ability to refactor are essential.

Tech stack is flexible as long as you can deliver clean, well-documented code and a simple deployment script. Once the extension runs smoothly on the target portal, we’ll wrap up with a brief hand-off session so my in-house admin can manage future slot parameters on their own.

If you have verifiable experience creating login-protected appointment tools for U.S. portals, let’s talk timeline and milestones right away.
