Four separate curricula, each sequenced so every topic only assumes what came before. Pick the one that matches where you are heading — or work through all 241 topics in order. Progress is tracked per roadmap in your browser; no account needed.
From Spring Boot developer to Agentic AI engineer
Seventy-five topics in dependency order, from your first ChatClient call to multi-agent systems running in production. Nothing here assumes Python, a data-science background, or a GPU.
Who it is for: Java developers who want to build LLM and agent features
From Spring Boot novice to enterprise architect
Sixty-eight topics covering every layer of modern enterprise Java: Spring Boot internals, REST API design, microservices, RabbitMQ and Kafka, DevOps, and the system-design patterns senior interviews actually ask about.
Who it is for: Java developers with 1–3 years of experience moving toward senior and architect roles
From basic authentication to zero-trust architecture
Forty topics covering every authentication mechanism, every authorisation model, every major attack class and the compliance frameworks that govern them — ending in a zero-trust platform design.
Who it is for: Backend engineers responsible for authentication, authorisation and compliance
From core Java recall to production war stories
Fifty-eight topics covering what Java interviews actually test: the language semantics behind the stock questions, collection and JVM internals, concurrency, and nine real production incidents — memory leaks, CPU spikes, pool exhaustion and load collapse — told as stories you can retell in a room.
Who it is for: Java developers preparing for interviews at any level, and engineers who want the internals behind what they use daily
