Learn it, then nail the interview
Spring Boot, Spring Security, Spring AI, Kafka and Spring Cloud — IoC, REST APIs, JPA, JWT auth, RAG, tool calling, MCP, resilience patterns, distributed transactions and production operations — full story-driven chapters to learn it from scratch, plus a real interview question bank to prove you know it.
What's inside
Learn From Scratch
Story-driven chapters that build every concept from first principles — dependency injection, the filter chain, RAG pipelines, partition assignment — with real Java/Spring code throughout.
Real Interview Questions
A curated question bank drawn straight from the material, with an AI tutor that builds a complete zero-to-expert answer for every question, on demand.
Diagrams, Chat & Flashcards
Generate a visual diagram for any topic or question, ask the AI tutor a follow-up, and review with spaced-repetition flashcards that bring weak spots back sooner.
