Spring Ecosystem

- Spring Boot 3.x create micro service skeletons, auto configuration, actuator health checks, and easy 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.

- 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. Frontend Proficient working within existing Angular/TypeScript/NodeJS/NPM frameworks.
