Paid Request : Need Cs-Cart Developer

We are looking for an expert cs-cart developer.

Our website is based on Cs-cart V 4.7.3 and we have a few payment gateway integration and fixing of errors on our website based on Cs-cart 4.7.3 as follows :
- Customers are getting logged out after returning to the website from the payment gateway after a failed or cancelled payment. We need to fix this so that they don’t get logged out and they can see their order details.
- Payubiz PG : We have a payment gateway (Payubiz) where lot of payments are getting deducted but not getting reported into the admin panel or even payment gateway backend. Those orders are then going into the incomplete status. We need the payment gateway to be integrated freshly with the latest API/code available for this PG.
- Razorpay PG : Orders not getting created for successful payments sometimes. We need the payment gateway to be integrated freshly with the latest API/code for this PG.

- Cashfree PG : We already have a plugin for this. We need this to be installed and setup with CS-Cart 4.7.3. The plugin is attached here and the documentation can be found here https://docs.cashfree.com/docs/
- Issue with a product gallery CSS as its not displaying correctly.
- Lot of labels and variable are showing an underscore _ symbol in front of them both on the frontend and backend. We need to fix this.
