" Hindi/German speaking person is preferred " Hello, I'm looking for a full-stack developer (ideally with experience of developing comparison portals) to integrate the payment provider Mollie via API I operate a comparison portal for repairs for electronic devices such as smartphones, tablets, laptops, etc. Workshops can register there and indicate their repair services with prices. I currently have a payment provider and I want to integrate a second payment provider. You are welcome to take a look at the comparison portal beforehand. https://reparaturmacher.de " website is made in custom PHP and JavaScript " It is not a normal, simple page, but a comparison portal and every workshop must log into the Mollie account in its backend and the correct data must be stored and our commission set correctly, depending on which workshop has which tariff. And the correct workshop must be assigned in the checkout. Is that okay with you? I think Mollie is even easier to integrate. https://docs.mollie.com/reference/v2/payments-api/create-payment The checkout is currently only optimized for one payment provider. The checkout also needs to be optimized. https://www.figma.com/proto/PDgiWkqttPQqhY1KZwqzGU/Checkout-Desktop-OnePager?node-id=1%3A2&scaling=scale-down&page-id=0%3A1 https://www.figma.com/proto/gBtj3Ys1Q8Fla2WsmPUZ2e/Checkout-Mobile-scrollen?node-id=1%3A3&scaling=scale-down&page-id=0%3A1 Checkout optimization is paid extra. In the first step, we can place the payment providers on the current checkout and optimize the checkout later. What do you need from me? For me it is important that you can do that. It is of little use to me if you stop in the middle of a project or do not point any further. I don't want to waste any more time.
