Tech Stack Selection for a Salon App

I’m building a salon app with features like booking, staff scheduling, and payments. What tech stack (frontend, backend, database) would you recommend for fast development, scalability, and smooth performance? Any real-world examples would be helpful.I’m building a salon app with features like booking, staff scheduling, and payments.
