Nature of work · Backend Development
Build and tune Java backend APIs, handling REST/GraphQL endpoints, data validation, error handling, security, and database migrations/optimizations. Also test AI coding tools in intensive bursts and report bugs, traces, screenshots, and feedback to researchers.
""Design, develop, and optimize REST and GraphQL endpoints for scalable APIs.""
Tech stack maturity
Mainstream Modern cache hit
The stack centers on widely adopted enterprise technologies like Java, REST, GraphQL, SQL, schema design, API security, and database migrations, which are characteristic of modern but not bleeding-edge or cloud-native-specific engineering.
