## Job description

We are looking for a strong **Regular Fullstack Developer (.Net + Vue)** to collaborate with us on a **freelance basis** for a greenfield project in the retail industry.

In this engagement, your main drive will be crafting modern, high-performance user interfaces in Vue.js, while leveraging your .NET background to build and integrate supporting backend services. You will collaborate within a focused, self-sufficient two-person engineering team (working alongside a Senior Developer) building a multi-tenant dashboard application from scratch. The client has developed a Proof of Concept (POC), which will serve purely as a reference for business logic to help us architect and write the new system from the ground up.

If you have a strong .NET background, feel confident building user interfaces in Vue.js, and enjoy creating systems from the ground up, this project is a great fit

**Requirements**

#### What you will do

- **Build from Scratch:** Help design and develop a greenfield retail dashboard application using .NET/C# on the backend and Vue.js on the frontend.
- **Integrate External Systems:** Connect the application with external retail and ERP platforms such as Shopify, Patchworks, and RFID tracking systems.
- **Work with Cloud Infrastructure:** Implement multi-tenant architecture hosted on Azure with a SQL Server database.
- **Translate POC into Production Code:** Use an existing prototype as a business logic template to write clean, scalable, and maintainable production software.

#### What we’re looking for

- **Commercial Experience:** 3+ years of hands-on experience as a Fullstack Developer working with .NET/C# and Vue.js.
- **Product Thinking:** Self-driven approach to feature design and technical implementation, capable of defining functional requirements and basic user flows independently to ensure fast, continuous delivery.
- **Database & Cloud:** Practical knowledge of SQL Server and core Azure services.
- **Integrations:** Experience working with REST APIs and third-party integrations (e.g., e-commerce platforms, ERP systems).
- **Self-Reliance:** Ability to take ownership of delivery within the agreed scope and collaborate effectively in a small, agile team.
- **Language Skills:** Good command of English (B2+) to ensure smooth communication.
- **Availability:** approx. 40h/week (B2B contract, hourly rate).

**Nice to Have:**

- Experience with multi-tenant application architecture.
- Prior exposure to retail tech, e-commerce, or logistics domains.
