Full-stack Developer for Dental SaaS Web Platform Enhancement

I am currently preparing to launch a SaaS platform specifically designed for dental therapists. Approximately 80% of the platform has already been developed using Lovable, and the core functionality is in place. I am now looking for an experienced developer/product expert who can help take the platform to the next level and prepare it for launch. The main areas where I need assistance include: Payment integration: Implementing convenient and reliable payment options for users. User experience: Improving the overall UX and making the platform more intuitive and user-friendly. UI refinement: Polishing the existing interface, improving layouts, and paying close attention to design details. Feature development: Turning new ideas and planned features into well-designed, functional solutions. Testing and optimization: Identifying issues, improving performance, and ensuring the platform is ready for real users. Ongoing development: Helping us continue developing and improving the product as new ideas and requirements emerge. We already have many ideas for the platform's future, but we need someone with strong technical and product experience who can help us turn those ideas into practical, high-quality features. I am looking for someone who can not only write code, but also understand the product, identify opportunities for improvement, and provide suggestions based on their experience. If you have experience working with SaaS platforms, Lovable, modern web applications, payment integrations, UI/UX, and product development, I would be very interested in discussing the project with you.
