Replicating a module

We need a senior C# and ASP.net developer to build a web module for us. The module is supposed to work with Bitwarden's open source password manager. Bitwarden already has this module but it's under different license and we want to have our own. The senior developer must also have a working experience with Single Sign On and SAML (Security Assertions Markup Language). We want the SSO module of Bitwarden to be technically re-written but the following 3 points to be kept in view. 1. The new re-written version must be significantly different and the code must be structured in a different way. This is extremely important to avoid copyright issues. Therefore, the Bitwarden's module must only be used for inspiration. 2. We will have a ton of stuff that will need to be removed after we determine we don't need it. 3. We might have some features that will have to be added after we determine that we need it. 4. We will need you to be able to deploy the new module along with Bitwarden's core open source code to AWS Lambda (Serverless) instances. We will not be hosting this on fixed resources. 5. We will need you to write a TerraForm or CloudFormation configuration that will be able to provision all the required resources i.e. Lambda functions, Databases, VPCs etc to deploy an instance of the new Bitwarden version at any given time.
