I worked with the Be-cloud team on the EasyConnect/Online project to implement a connection interface supporting the following protocols:

- Kerberos

- WS federation

- OpenId / Auth2

This connection interface is designed to be fully configurable and deployable both online and on-premise within the client's IT department.

This project involved 4 phases:

- Requirements gathering

- Analysis and design

- Development

- Documentation and CI/CD implementation

Outcome: An add-on interface for an ASPX project that can be integrated into other projects later.

The internal team works with technologies other than .NET C#. One of their clients had commissioned them for the takeover and maintenance of a project developed in C# .Net, so they needed a specialist in this technology.
