Backend Engineering Mastery: APIs, Databases & Microservices

=== COURSE OVERVIEW ===

Welcome to the Backend Engineering Mastery course! This comprehensive 6-week program is designed to turn you into a skilled backend developer, capable of building the server-side logic, databases, and APIs that power modern web and mobile applications.

Backend development is the backbone of the digital world. In 2026, the two strongest options for backend development are JavaScript/TypeScript (the fastest path if you want to work across the web stack) and Python (versatile, with strong demand in data and AI)[reference:1]. Java also remains one of the most stable and high-demand languages, especially for enterprise, backend, and mission-critical systems[reference:2].

This course gives you exposure to all three ecosystems, making you a versatile and highly employable backend engineer.

   ✅ Authentication and authorization (JWT, OAuth2)
   ✅ Microservices architecture and Docker
   ✅ Cloud deployment and DevOps basics
   ✅ Monitoring, logging, and observability
   ✅ Building a complete capstone project
