Job: integrate Amazon Pay and PayPal into Netperles, a French cultured-pearl jewelry shop that has been selling online since 2002.
PEEL Shopping 9
The shop runs on PEEL Shopping 9, a French e-commerce product with no framework under it. Nothing in it tells you where payment code belongs.
So the job started with reading. I traced checkout end to end until I knew which files actually ran when someone placed an order, then wired the two providers into that path.
Shipping it
Both providers are live on the shop today. Getting there took longer than "add two payment methods" suggests, and most of that time went into understanding the code around the checkout rather than writing new code.
