How a tech stack actually fits together, one real layer at a time.

• Tech Stack FundamentalsNEWThe stack knowledge every full-stack and AI-app dev needs — a real browser, server, and database, simulated side by side.
• ArchitectureNEWWhy the same task can touch one file or ten, how an AI pipeline is actually wired, how to weigh real tradeoffs, and how to shape a brand-new app — four live checks.
• API FundamentalsNEWAn endpoint, a method, a status code — the three things every API call actually is. A real in-memory REST API to build a request against.
