A personal Senior .NET / AI software-engineering knowledge base — authored in Obsidian, published as a static website, and paired with a .NET RAG backend that searches and answers over the same notes.
🔗 Live site: devbook.zip
A structured collection of software engineering notes covering 11 topic areas, designed for learning and interview preparation at a Senior .NET / AI engineering level. Every note follows a strict quality bar: intro in your own words, concrete examples, pitfalls, tradeoffs, interview-style questions, and curated references.
The same notes feed two things: a static website (write in Obsidian → publish with Quartz Syncer → auto-deploy) and a .NET RAG backend — a personal R&D proof of concept for learning retrieval mechanics (ingestion, chunking, embeddings, vector search, reranking, and evaluation) over real content.
