We are looking for a developer (or a team) to create an automated service for ordering home services in Warsaw. Main analog and reference: CleanWhale.pl — we take the convenient step-by-step logic of the calculator, the grid of additional services, the interface for selecting frequency, and the overall principle of placing an order from here. 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.
