NoSQL Jobs

I’m building a web-based platform where parents and swimmers can quickly find an instructor, check real-time availability, pay for a lesson, and manage everything from a personal dashboard. The look and feel should be youthful and vibrant—bright colours, playful accents, and a clean, mobile-first layout that appeals to kids and adults alike. Core user flow 1. Customers land on the site, browse instructor profiles, pick a location, see open slots, and confirm a booking. 2. Payment is processed on the spot (Stripe or a comparable gateway). The system automatically withholds taxes and platform fees. 3. Instructors receive the remaining balance, visible in their earnings tracker.

Once the platform is agreed, I will look to you to design the schema (or data model), implement the database online, seed it with some sample data so I can run realistic tests, and deliver clear connection details for my dev team.
