Booking Form App Development

I need a straightforward application whose main purpose is a Formulir pemesanan (booking form). The surrounding pages can stay minimal; my priority is a smooth booking workflow that captures all required fields, stores the data safely, and sends immediate confirmations to both the user and me.

Here’s what I expect:
• A clean, responsive booking interface in Indonesian (English fallback is fine).
• Server-side logic that validates entries, records them in a database, and fires email or in-app notifications.
• An admin view where I can search, sort, and export bookings.
• Clear hand-off: source code, short setup guide, and a quick walk-through call.

Tech stack is flexible—feel free to suggest the framework or platform you’re fastest with, as long as it remains easy for me to maintain later.
