Cloudflare & Lovable Expert Needed to Configure Custom Domains for SaaS App

I am looking for an experienced Cloudflare and Lovable expert to help configure custom domain functionality for a Lovable-built app.

The goal is to allow users of the app to connect their own custom domains and subdomains to the platform.

We are currently trying to use Cloudflare for SaaS, but I am having difficulty configuring it properly. I need someone who understands:

Cloudflare for SaaS
Custom hostnames
SSL certificates
CNAME setup
Domain verification
DNS configuration
Lovable app deployment/custom domains
SaaS-style custom domain architecture

The ideal person should be able to review the current setup, identify what is missing or misconfigured, and implement a clean, reliable solution.

I am also open to alternative solutions if Cloudflare for SaaS is not the best option for this use case.

The final setup should allow app users to:

Add their own domain or subdomain inside the app
Receive clear DNS instructions
Verify domain ownership
Automatically connect the domain to the correct Lovable app/page
Have SSL/HTTPS working properly

Please apply only if you have real experience with Cloudflare for SaaS, custom domains, DNS, SSL, and SaaS app domain configuration.
