Woocommerce Plugin Development Expert Needed

We are using a plugin called Funnelkit

It is working fine but the one click upsell feature in the plugin is not working because it doesn’t support Airwallex payment gateway for one click upsell

We have confirmed that it can be implemented and we need to build a connector inside funnelkit plugin for it so it can support Airwallex payment gateway for one click upsells

We need a highly experienced developer who can do that
