Shopify developer needed for free trial product — 2

I’m using Recharge app for subscription on my Shopify store.
I want to set 3 types of product – one-time, recurring (subscription), free-trial.
I use Recharge workflows for this.
But after free trial expired, it doesn’t continue to fully paid subscription.
It continues the free – trial product.
Want to hire developer already have experienced in it.
Otherwise, don’t bid here please.
