Nature of work no kras

Vague JD — no KRAs present to derive a specific nature of work.

Tech stack maturity

Mainstream Modern

The stack centers on Java, Spring, Spring Boot, Maven, and Hibernate, which are widely adopted mainstream enterprise technologies that are modern but not bleeding-edge cloud-native.
