Develop Strategic Session Feature for Web-Platform

Build a “Strategic Session 1:1” feature for a web platform

Project Description
I am looking for an experienced full stack developer to build a new feature inside an existing web platform for strategic consulting sessions.

The goal is a very simple click-and-create UX.

A consultant should be able to click “Activate Strategic Session” and enter only:
* 2 short lines about the session focus
* target audience
* duration: 30 / 60 / 90 / 120 minutes
* Zoom or Google Meet
* price
* basic availability

The system should then automatically create:
* a public booking landing page with shareable link
* AI-generated landing copy
* available time slots
* Stripe / PayPal payment choice
* automatic call creation after payment
* a private session page for recap and follow-up

Client flow:
* open booking link
* choose slot
* pay with Stripe or PayPal
* receive confirmation and session link

Current stack:
React
FastAPI
MongoDB
Docker Compose
Nginx

I need someone who can design a clean UX and implement the feature carefully inside an existing codebase.

Nice to have
Experience with Stripe, PayPal, Zoom API, Google Meet/Calendar, SaaS or booking platforms.
