alipay intergration in shopify

I am running a German based e-Commerce shop dedicated to Chinese, but the shop is mostly in English. The shop runs on the Shopify platform. Now I would like to add Alipay to the portfolio of payment options. Given that Shopify does not offer Alipay as standard payment option yet, but allows for programned plug-ins, I am looking for an experienced programmer to fully integrate Alipay into my shop: Requirements: - Experienced with integrating Alipay into Shopify Shop (provide references!!!) - Execution of project until test orders via Alipay payment indeed work - Western Europe / German background preferred, but now must - Fast and reliable execution of project in close alignment with German teams and Shopify team (be aware of time zone issue)
