Handle post sales technical support for my software products

I am looking for a Freelancer to provide high-quality post sales technical support for my software products. The software products primarily cover the web and windows platforms, and I need personalized user support for customers. Therefore, this will require an experienced professional who has knowledge in this area. It is important that the services are provided in a timely manner, and I require a same day response time. The Freelancer should also have an understanding of the software development process. If you are interested in this project and believe you can provide great technical support, I'd love to hear from you.
