VB.NET App Improvement - Fulfillment Function Migration

I'm looking for a skilled VB.NET developer with Shopify API experience to update our software. We need to migrate from a deprecated fulfillment function to the new one, focusing on seamless integration. Key Tasks: - Modify existing VB.NET application to integrate with the new Shopify API fulfillment function - Ensure smooth transition with rigorous testing for bugs and potential issues - Implement automation for order fulfillment to increase efficiency of our processes Ideal Candidate: You should have significant experience with VB.NET and be familiar with the Shopify API. A background in working with order fulfillment functions is desirable. Demonstrable experience in software migration is a must. Efficiency and attention to detail are crucial. Notes: This is a vb.net project that is currently developed in VS 2015. This application gets Netsuite fulfillments and sends that data to Shopify using Shopify API’s. The application is fully developed and in production however a recent change with Shopify deprecated the Fulfillment process. Experience with vb.net, Shopify API calls using vb.net, Json and Shopify API migration technologies helpful to make this a good fit.
