I built as a quick proof-of-concept with a low-code tool. The core of the site is a content-based recommendation engine that relies on each movie’s metadata (mood tags, genre, tempo, colour palette, etc.) to suggest the next title. Everything works for demo purposes, but I now need a rock-solid, production-ready version. Here’s what I’m after: the existing front-end and logic need to be refactored or rebuilt so the platform can handle real traffic, persistent data, and a CI/CD pipeline. I’m open to the tech stack you propose as long as it keeps the recommendation engine fast and explainable. You’ll optimise queries, set up a proper database, containerise the app (Docker or similar), and deploy it to a cloud provider with monitoring and automatic scalin...
