The best platform for a Glassdoor-like website is a modular, cloud-native architecture.

This involves a React/Vue frontend for dynamic user interfaces, a Node.js/Go microservices backend for scalable and independent functionalities, and a robust data core combining PostgreSQL (for structured data), Elasticsearch (for fast search), and potentially a Graph database (for complex relationships).

All this is hosted on cloud services (AWS/GCP/Azure) for scalability and managed resources, integrating AI/ML (Python) for advanced analytics like sentiment analysis and personalized recommendations.
