Need experienced PHP full-stack developer for SaaS platform

I'm looking for an experience PHP developer to take over ongoing development of my platform ---------- 's almost ready to launch, but my current developers have become unreliable.
Please only reply with examples of SaaS platforms you have worked on, ideally subscription platforms also integrated with Stripe.
The perfect candidate will also have the ability to have some communication time available during the US working day, but exact hours are not required.
This will be project-based, but for the reliable candidate, will turn into ongoing work.
The perfect developer will also have some knowledge of scaleability of a platform, and writing efficient code, and VERY STRONG communication.
