Custom Changes in Shopify

I am looking for someone who can help me make custom functionality changes for my Shopify store. The changes I'm looking for are related to functionality and I have a specific feature in mind for the change. The priority of the changes is medium priority. I am looking for someone with experience in making such changes to Shopify stores. As this is an urgent project, I need someone who is able to quickly deliver the changes I am asking for. If you think you can help me out with this project, please contact me. Thank you!
