ASP.NET & Angular API for Third-party Data Transfer

I'm seeking a skilled developer to help me set up an API that connects our ASP.NET and Angular applications to a third-party site for data transfer. The data that we need to transfer includes User data, Product data, Transaction data, and Orders. Our main goal here is to ensure seamless and secure transfer of information between our systems and the third-party site. This will involve:

- Extracting Name and contact information, Purchase history and preferences, Order details and status, getting order results and writing them into our local database, then forwarding this information to the Customer's request.
- Ensuring the data transfer is efficient, accurate and secure.
- Managing API calls effectively with ASP.NET and Angular.

Ideal candidates for this project should have:
- Proficiency in ASP.NET and Angular
- Experience with API development and Integration
- Strong Data transfer management skills
- Excellent understanding of security protocols

This is a critical project for us, and we are looking for someone who can deliver a high-quality, robust solution that is scalable and reliable. If you think you have the right skills and experience for this, we would love to hear from you.
