Many students have compiled detailed summaries and code snippets available on Video Deep Dives:
Modern backend engineering has evolved beyond simple server-side logic. Key areas to cover include: Communication Protocols : Mastery of HTTP/1.1, HTTP/2, and HTTP/3 , as well as gRPC, WebSockets, and WebRTC for real-time applications. Database Mastery : While NoSQL is popular, 2026 trends emphasize strong SQL and PostgreSQL foundations for structured data and complex queries. API Design : Moving from basic CRUD to building distributed systems and integrating AI through clean RESTful or GraphQL endpoints. Security & Performance : Foundational topics now include JWT authentication fundamentals of backend engineering free download upd
