Regular Fullstack Developer (.Net + Vue) - Freelancer

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

• 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.

Requirements

• 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.
