Java for Enterprise Systems Learning Roadmap

This page is the orientation brief we hand hiring managers — three sections only, each with artifacts you can forward to procurement without editing.

Skills map

We sequence capabilities in the order release trains fail: packaging clarity, data access discipline, integration contracts, observability, then coordinated rollouts. Color bands below map to modules in the catalog — not certifications.

Packaging Data Contracts Observability

Tool stack breakdown

Build + quality

Gradle Enterprise scans, OWASP dependency checks, ArchUnit-style tests where applicable.

Runtime surfaces

Payara Micro, Spring Boot 3.x, Testcontainers, WireMock for brittle integration edges.

Signals

OpenTelemetry traces, Prometheus RED panels, structured logs aligned to PDPA minimization guidance.

Capstone project outline

  1. Week 1–2: freeze three interdependent service contracts with OpenAPI baselines.
  2. Week 3–4: rehearse database migration ordering with rollback scripts attached to tickets.
  3. Week 5: tabletop incident with mentors playing product + SOC + finance roles.
