DsThakurRawat/Backend-from-first-Principle ? reverse-engineered prompt

Build me a clean, easy to browse learning site for backend engineering fundamentals, based on the topics in this repo. I want the homepage to introduce the series and make it simple to jump into each section like HTTP and CORS, routing, auth, APIs, databases, caching, queues, logging, security, scaling, testing, Kafka, WebSockets, and deployment.

Make each topic page readable like good study notes, with code examples, headings, and a clear table of contents. Add a simple navigation so I can move between chapters without getting lost, and make it look good on both desktop and mobile. If it helps, include a search or quick filter for topics so people can find things fast.

Keep it modern, fast, and beginner friendly, and use the existing content in the repo as the source. If you need to look up current docs online for any implementation details, do that.
