Nature of work
no kras
Vague JD — no KRAs present to derive a specific nature of work.
Tech stack maturity
Mainstream Modern
The skill set centers on Java, Spring Boot, Maven, Swagger, microservices, and Splunk, which are widely used in current production backend development but not especially cutting-edge cloud-native tooling.
