Nature of work · API and service implementation

Build backend APIs in Python/FastAPI and Java/Spring Boot, own request flow into business logic and PostgreSQL persistence, and add OAuth/JWT auth plus RBAC. Also write integration/unit tests and review code.

"Design and implement REST APIs in Python (FastAPI) and Java (Spring Boot)"

Tech stack maturity

Mainstream Modern

The stack centers on widely adopted modern backend technologies like FastAPI, Spring Boot, PostgreSQL, JWT, OAuth 2.0, and REST, indicating a contemporary but not cutting-edge or cloud-native-only profile.
