Applicants are required to meet the following criteria:


C# / .NET — can build and debug a .NET application; understands classes, async, LINQ, dependency injection.
React — has built components, handled state and props, called an API from the front end. TypeScript exposure is a plus but not required.

TypeScript, EF Core, SQL / SQL Server
REST API design, domain-driven design, the repository pattern
Docker, AWS (ECS, RDS, ALB), CI/CD pipelines
Authentication / OAuth2 / OIDC
Experience with AI coding assistants (Claude Code, Copilot, Cursor)

Who this suits


0 - 2 years' experience, a recent graduate with real project work, or a bootcamp graduate with a portfolio.
Wants to learn modern .NET, React, cloud, and AI-assisted development in a mentored setting.
Careful and methodical — this project is about faithfully matching how an existing system behaves, so attention to detail matters more than speed.
