Javatrip Web App Development (production-ready first version)

Title:
Developer needed to build a web app for Javatrip, www.javatrip.se, which is a fundraising sales platform for schools and sports teams

Description:
We are building a web-based app for Javatrip, a fundraising platform used by school classes and sports teams to sell products through personal seller webshops.

We are looking for an experienced developer to build a production-ready web application with:

role-based access (admin, team leader, seller)

public seller webshops (unique links / QR codes)

campaign-based sales

order aggregation, statistics, and pick lists

clean, scalable architecture suitable for future growth

Payments are handled outside the system in the MVP.
The project focuses on correct business logic, clear user flows, and maintainable code — not a quick prototype.

A detailed scope is attached.

Requirements:

Strong experience building web applications (SaaS or similar)

Ability to design and implement clean backend logic

Comfortable making architectural decisions

Clear communication in English

Nice to have (not required):

Experience with marketplaces, e-commerce, or order systems

Experience with scalable web architectures
