• Collaborate with analysts and fellow developers in agile sprints.
• Explore new technologies and contribute to the improvement or modernization of existing applications (both greenfield and refactoring projects).
• Contribute ideas to enhance performance, security, and long-term maintainability.

Who are we looking for?

• You have strong knowledge of C#, .NET (Core), Blazor, Angular, React, and SQL Server.
