Expert WordPress developer for AI glamour site

We need to bring in a second developer to help us launch a new AI art venture that combines AI-generated glamour & fantasy art. It is a user-generated AI art platform with community features (like comments and forums) and dozens of galleries containing thousands of images and videos. We have built the site with custom code on WordPress using a minimum of plug-ins. Nearly all of the site's functionality is handled through functions.php and custom templates. We heavily rely on ProfilePress for user registration, profile management, paid memberships and more. We have three payment tiers for access to three levels of content. We have a current solo developer in New York who has been working on the project since April. So we are looking to increase the project speed and to finalize deliverables by keeping these things in mind: (1) We can't slow down our current developer further, so we need a self-starter who can join an existing project, take part of the Scope of Work document, and implement the code independently -- without ever overwriting or interfering with the existing developer's daily work (weekdays only from 1 to 9 pm Eastern). (2) We are very detail-oriened, so you will have daily access to a project manager (me) and to a Slack account for the project. (3) We want someone who is comfortable interacting with Claude.ai and is not skeptical when we devise a suggested change in the code that needs review and implementation. The candidate should definitely be comfortable working with AI on all aspects of their engagement. (4) I am attaching some examples of the deliverables that we believe a second developer could work on independently. Some of these are very quick fixes, some will take hours of work. It is possible that this can turn into a longer-term engagement after launch if the Upwork candidate proves proficient across a number of our needs for ongoing support and development.
