Quarkus Expert

Overview

General expertise for Quarkus 3.x — the Kubernetes-native Java framework built on Vert.x, Netty, and GraalVM. Quarkus unifies reactive and imperative programming, performs most framework wiring at build time (via Jandex and the Quarkus build system), and ships Dev Services for zero-config local development.

Key pillars covered by this skill:

• CDI Arc — build-time CDI, scopes, qualifiers, interceptors, decorators, CDI events
• Configuration — MicroProfile Config, @ConfigProperty, @ConfigMapping, profiles, config sources
• Dev Services — automatic Testcontainers for databases, Kafka, Keycloak, Redis, and more
• Native build — GraalVM native compilation, reflection registration, resource inclusion
• Testing — @QuarkusTest, @QuarkusIntegrationTest, @InjectMock, @TestProfile, @TestTransaction

Quarkus version: 3.x (Jakarta EE 10, jakarta.* packages)
