.NET Core Worker Service with Informix

I'm looking for a talented developer to create a worker service using .NET Core 8. The service must be able to:

- Perform operations on an Informix database, specifically fetching and updating records
- Be deployable on both Linux and Windows environments

The service will primarily handle financial data, so experience with this type of data would be advantageous. For the integration with the Informix database, I prefer using direct API calls.

To streamline our collaboration, I would appreciate it if you could send me a simple console application that fetches data from the Informix database and updates a record. If your application works, I believe we can establish a productive working relationship.

Ideal candidates should have:
- Extensive experience with .NET Core
- Proficiency in Informix database management
- Skills in cross-platform deployment
- Experience working with financial data
- Knowledge of making direct API calls

If you're passionate about building reliable services and have the required technical expertise, I look forward to hearing from you.
