PROFILE
Jiho Lee
Worked on the Netflix/dgs-codegen repository to enhance GraphQL code generation and backend reliability using Java and Kotlin. Delivered targeted improvements to the Java InterfaceGenerator, refining getter and setter logic for interface fields and expanding test coverage to validate multiple configurations. Addressed GraphQL configuration issues by adding validation for overlapping schema paths and fixed regressions in interface setter generation. Focused on Jackson compatibility for generated Kotlin data classes, removing problematic annotations and introducing version-aware handling. Unified the Kotlin client generation flow, streamlined configuration, and improved logging for better CI triage. Emphasized test-driven development and robust serialization throughout the development process.

Oct 1, 2025October 2025 (Month: 2025-10) – Netflix/dgs-codegen: delivered targeted feature refinements to the Java InterfaceGenerator to improve correctness and configurability of generated interface code. Key changes include adding getters for interface fields and refining setter generation to apply only to non-interface fields by default (with an explicit override option). The InterfaceGenerator test suite was expanded to cover multiple configurations and schemas, increasing confidence in codegen behavior. No explicit bug fixes were documented this month; the focus was on robust feature delivery and validation through tests. Business impact: more reliable generated GraphQL interfaces, reduced downstream debugging, and faster integration for services relying on the code generator. Technologies/skills demonstrated: Java, code generation, GraphQL schema handling, test-driven development, and config-driven generation with clear commit traceability.
