Shopify Expert Needed for Custom Integrations

I am in need of a SHOPIFY EXPERT with strong web development skills to assist with custom integrations and coding on my Shopify store.

Specific tasks to be completed:
- Connect my Google/YouTube account to the Shopify website
- Connect my Merchant Center to the Shopify website
- Insert Google Tag Manager into the Shopify website
- Insert Google Adsense into the Shopify website
- Insert Google Analytics Tag into the Shopify website
- Link my Facebook account with the Shopify website

All accounts for these services are already established. I am specifically looking for someone who can provide custom coding or scripts for these integrations, rather than just standard integration.

The ideal candidate will have:
- Extensive experience with Shopify
- Strong web development skills
- Proficiency in custom coding
- Familiarity with Google services and Facebook integrations
- Ability to deliver high-quality work within a reasonable timeframe.
