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 established backend and web technologies like Java, REST, JWT, OAuth2, RDBMS/NoSQL, and common security/versioning practices, which fits a broadly modern but not bleeding-edge profile.
