WordPress/WooCommerce PHP Developer to Help Fellow Developer with eBay and Amazon Business APIs on an AWS Cloud Infrastructure

I have a client and have developed a Cloud Infrastructure WordPress Hosting platform using an AWS EC2 and built this entirely from Linux Fedora Silverblue and actually dives deeper into an Ubuntu VM 20.04 LTS which SSH's into an Ubuntu USA 20.04 LTS VPS Amazon Machine Image (AMI). When I launched that AMI I set up a LEMP stack. The client has an eBay Partner Network account (can probably find repos and docs from this woman that was interviewed: [login to view URL]), an Amazon Business/Associates/Seller + Amazon Web Services (AWS) account. I have an AWS account as well and built this through the Ubuntu VPS. This client is basically a boutique developer agency that's been overloaded with work so they brought me on for this project and they've adopted something really interesting with the aim of proving the "Collaborative Enterprise" model, which focuses on four (4) primary pillars: 1.) Define and build a shared purpose; 2.) Cultivate an ethic of contribution; 3.) Develop scalable processes for coordinating people's efforts; 4.) And, create an infrastructure in which collaboration is value and rewarded. With the above considerations in terms of how they operate, they've integrated the Capability Maturity Model (CMM) - which means code is no longer developed by individual, flywheeling programmers - it becomes a sound workflow which two versions of each stage in the development lifecycle. Here are the development stages (in a nutshell): 1.) Development (THIS IS THE ONE YOU'LL WORK ON AND YOU'LL BE CREATING DEV1) 2.) QA 3.) Integration Testing 4.) User Acceptance Testing 5.) Staging 6.) Production In terms of workflow which is the Cloud Information Model (CIM) to bridge the upstream and downstream gaps in Linux development - specifically between AWS, Salesforce (not using) and Linux Foundation. The project is to produce and send in one (1) of the two (2) PHP RESTful API integration with the WordPress RESTful API, Woocommerce REST API, AWS RESTful API, Amazon Marketplace Web Services (MWS) RESTful API, AND THE MOST IMPORTANT (PROBABLY FIRST THING TO SUBMIT), THE EBAY PARTNER NETWORK RESTful API. Can you please quote me as more of a peer that's got too much on their plate? I'm really hoping to not spend anymore all nighters doing this alone and the open source community seems to be closed these days ha! Thanks so much and i hope you're doing well and staying safe. Very best, Liam
