Nature of work · Backend Development

Build and improve Java backend APIs, including REST/GraphQL endpoints, data validation, security, and database migrations. Also test AI coding tools in intensive bursts and report bugs, traces, screenshots, and workflow 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.
