AI-Powered Custom E-commerce Development

I’m building a full-stack e-commerce site and want it developed on a completely custom platform—no Shopify or WooCommerce plugins. The core differentiator will be an AI-driven engine that serves personalized product recommendations to every visitor in real time, adapting as they browse and buy.

Beyond the usual catalogue, cart, payment and order-management flow, I need you to design, train and deploy a recommendation system (collaborative filtering or deep-learning based—TensorFlow, PyTorch or your preferred framework) that ingests user behaviour, purchase history and product metadata. The model should expose an API the storefront can call instantly so suggestions appear without slowing the page. something like loreal modi face but with a twist

Key deliverables:
• Responsive front-end and secure back-end for the store
• Recommendation engine with training pipeline and retraining hooks
• Admin dashboard showing lift metrics for the AI suggestions
• Deployment scripts / Docker files so the whole stack can be reproduced
• Clear developer-level documentation and a brief hand-off session

I’m open on language, database and cloud provider as long as scalability and clean code are prioritised. Let me know your proposed stack, prior examples of custom e-commerce builds, and any experience fine-tuning ML models for live production.
