Freelance Full stack .NET Developer (Angular / React)

Job description

You build the business applications that train traveller’s, grid operators and government services use every day. With C# and .NET at the back, Angular or React at the front and a pipeline that just works, you turn a backlog into software that goes live and stays live. Key takeaways You build full-stack applications in C#/.NET and Angular or React for public-sector and utility clients. You own your features from API design to deployment, with clean code, tests and Azure DevOps pipelines. You bring 5+ years of .NET experience and the calm of someone who has survived a production incident or two. Your role Build & Deliver You design and build REST APIs in modern .NET, with Entity Framework Core underneath. You build front ends in Angular with TypeScript, or in React where the client chose that path, that people can use without a manual. You turn functional analyses and user stories into working features, sprint after sprint. Quality & Pipelines You write unit tests because you like sleeping at night, not only because the definition of done says so. You keep code clean, readable and SOLID, so the next developer does not need an archaeologist. You set up and maintain CI/CD pipelines in Azure DevOps, so a release is routine and not an event. Data You design data models and write SQL that performs, on SQL Server and, at several clients, on Oracle. Team & Client You work in Scrum teams with analysts, testers and architects, and you speak up when a story does not add up. You help less experienced developers along with code reviews and a fair amount of patience. You represent adesso at the client: reliable, clear and pleasant to work with. Required Skills & Knowledge .NET & API’s You have 5+ years of professional C# / .NET development, including recent work on .NET Core, .NET 6 or .NET 8. You design and build REST / Web APIs and know your way around Entity Framework or EF Core. Front-end You build with recent versions of Angular, TypeScript, HTML and CSS. React experience is a strong plus: several clients ask for it next to Angular. Data You are at home in relational databases and SQL. SQL Server is a given; Oracle and PL/SQL give you a clear edge. Devops & Quality You use Azure DevOps, YAML pipelines and Git every day. You write unit tests with xUnit or NUnit. Nice to have Azure services such as App Services, API Management, Storage and Azure AD B2C. CQRS, event-driven design, and state management with NGRX. Docker and containers. Experience in the public sector or with utilities. Your profile you bring at least 5 years of full-stack experience with .NET and Angular or React, at medior to senior level. You work as an independent freelancer and are open to assignments of 12 months or longer. You are fluent in Dutch plus English. French is a plus. You are fine with hybrid work, with regular days on site in Brussels, Ghent or Antwerp.
