SaaS Infrastructure and Backend Developer

I need a freelancer to prepare and manage the infrastructure, backend, security, and scalability of my SaaS. The work includes setting up reliable systems, building a secure backend, and ensuring the platform can grow smoothly as usage increases. I’m looking for someone who can take ownership of these areas and help create a stable, scalable foundation for the product. The tool similar to Kajabi, Payhip, Gumroad but with built in product generators (please check out the landing page Kledge.ai) I'm expecting tens to hundreds of thousands of user traffic onto the platform that creators will bring onto it. And heavy use of generations. I need someone that can advise and help me on the infrastructure and back end and sort it out Kledge.ai
