Migrate & Update Shopify Website to Netlify

I'm looking for a professional to help me migrate my Shopify website, built with Gatsby, to Netlify. The primary goal of this migration is to simplify the deployment process, and allow for a non technical designer to make content changes.

Key aspects of the project include:
- Migrating custom themes and scripts: My current Shopify site has several custom themes and scripts that need to be transferred to the new platform.
- Updating the site: The website is a few years old and requires some updates to keep it relevant and functional.
- Content updates: The site needs a comprehensive content update.

Ideal candidates for this project should have:
- Extensive experience with Shopify, Gatsby, and Netlify
- Proficiency in migrating custom themes and scripts
- Skills in website content updating
- A keen eye for enhancing website design and functionality
- Ability to simplify deployment processes

Please provide examples of similar projects you've completed in your proposal. Thank you.
