Klaviyo and Shopify Integration Expertise

I am seeking a professional experienced in implementing the Klaviyo extension within Shopify to help set up and optimize essential email workflows for my brand. The required workflows include:

Order Confirmation Workflow: Ensuring buyers receive timely confirmation emails after a purchase.
Item Shipped Workflow: Notifying customers when their order has been dispatched.
Refund Workflow: Automating communication for refunds.
Abandoned Checkout Workflow: Encouraging customers to complete their purchase.
Monthly Stock Update Workflow: Sending regular updates to customers about new stock arrivals.
If you are familiar with alternative platforms or tools that might provide superior functionality for these workflows, I would greatly appreciate your recommendations and am open to exploring them.

Thank you!
