Task: Create a similar Mobile-First service in terms of convenience and design, but with simplified tariff logic and built-in gamification (“Housing Sharing”). Stack: We are considering options on WordPress + Elementor / WooCommerce, No-Code (Bubble / FlutterFlow), or your ready-made custom solutions.

Good day! We have a project on Next.js, React, Node.js, and Strapi. Currently, the main page is designed, and two secondary pages need further development. It is also necessary to design another 4–5 pages with adaptation and complex animations for different devices and connect them to the Strapi admin panel. Due to the change in the workload of the previous developer, we are looking for a new specialist to complete the project. We are looking for a responsible developer with practical experience working with this stack. In your response, please include examples of similar projects. The budget will, of course, be discussed.

The audience is already created, but is currently updated manually. The executor is required to: Propose the optimal implementation method. Specify what accesses and permissions will be needed. Estimate the cost and time for completion. Indicate experience working with Meta API and Make. After setup, provide a brief description of the logic of operation and the accesses used. Additionally, please clarify: is a complete daily replacement of the audience possible through the API and what limitations or risks may exist from Meta's side.
