Core Java & JDK 21+

• Modern language features records, sealed classes, pattern matching, text blocks, and functional APIs (streams, Optional).
• Concurrency & Parallelism virtual threads (Project Loom), Completable Future, Executor Service, Fork/Join, and basic lock/atomic primitives.
• JVM & GC tuning G1/ZGC behavior, heap dump analysis, JFR profiling, and module system (JPMS) usage.
• Logging / Instrumentation / Error Handling
• Build & Unit test foundation Maven/Gradle multi module builds, JUnit 5 + AssertJ, static code checks (SpotBugs), and basic GraalVM native image awareness.

Spring Ecosystem

• Spring Boot 3.x create micro service skeletons, auto configuration, actuator health checks, and simple security (JWT/OAuth2).,
• Spring Data (JPA/R2DBC) – entity mapping, query hint optimisation, reactive repositories, and transaction demarcation.
• Spring Cloud basics – service discovery (Eureka), API gateway pattern, externalised config (Config Server), and circuit breaker (Resilience4j).
• Either Spring Batch OR Spring MVC OR Spring Integration
• Spring Security fundamentals – CSRF protection, OAuth2 resource server setup, basic role based access control, and token validation.

Database & Data Access Engineering

• SQL & query optimization – complex CTEs, window functions, indexing strategies, and execution plan analysis (PostgreSQL/Oracle/MySQL).
• ORM performance – JPA/Hibernate mapping, N+1 detection, second level cache, batch inserts/updates, and @QueryHints.
• NoSQL & caching – when to use MongoDB, GraphDB, Redis (session/Cache aside), basic data modeling, and TTL/eviction policies.
• Migrations & transactions – Flyway/Liquibase versioning, multi DB transaction handling (JTA), and isolation level choices.

Design & Architecture

• Clean / Hexagonal architecture – ports and adapters, dependency inversion, and keeping frameworks at the outer ring.
• Domain Driven Design basics – bounded contexts, aggregates, domain events, and idempotent processing.
• API first & contract – OpenAPI/Swagger spec authoring, versioning strategy, and consumer driven contract testing (Pact).
• Event driven patterns – Kafka or RabbitMQ producers/consumers, out box pattern, and basic saga (choreography) implementation.
• Security: Public Keys / Hash Concepts. Design around Access Control, Role Based security.
• Awareness around: Microservices design Pattern
• Concepts like - Circuit breaker, load balancer

DevOps

• Containerization & K8s – Docker multi stage builds, Helm chart basics, pod liveness/readiness probes.
• CI/CD pipeline basics – Jenkins/Argo CD job that runs unit, integration, and static analysis steps; artefact publishing.
• Observability starter – expose Prometheus metrics, configure a basic Grafana dashboard, and ship structured logs to ELK.
• Testing & Quality Engineering 1. Test pyramid implementation – unit (JUnit 5/Mockito), integration (Testcontainers), contract (Pact).
• 2. Performance & load testing – JMeter script creation, baseline latency/SLO definition, simple analysis of results.
• 3. Static analysis & coverage – SonarQube quality gate, JaCoCo coverage threshold, SpotBugs rule set.
