Integrate Affirm Payment on Shopify Sites

I need an experienced developer to integrate Affirm on two of my Shopify websites. The integration should include:

- Displaying Affirm as a payment option at checkout
- Showing Affirm cost breakdown on product pages
- Adding Affirm promotional banners across the sites

I have the necessary Affirm credentials ready for the integration. However, the design of the Affirm logos and payment options needs to match my websites' current design theme.

Ideal skills and experience for this job include:

- Proficient in Java and other coding languages
- Extensive experience with Shopify and its payment integrations
- Strong understanding of web design and ability to match existing design themes
- Previous experience with Affirm integration is a plus
