We are looking for a strong Regular Fullstack Developer (Vue.js + .Net) to join us on a freelance basis for a greenfield project in the retail industry. In this role, 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 be part of 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 are a Vue.js specialist who feels comfortable navigating .NET architectures and loves clean-slate development, this project is a great fit!

• 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 Vue.js and .NET (C#)
• 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 assigned tasks and collaborate effectively in a small, agile team.
• Language Skills: Good command of English (B2+) to ensure smooth communication.
• Availability: Full‑time (B2B contract/hourly rates).
