During March 2026, Diego Mora developed dynamic model switching for the Gemini API in the google/adk-go repository. He introduced a modelName helper in Go to ensure that GenerateContent calls respect the LLMRequest.Model parameter, allowing runtime model selection and overriding the previously hardcoded model name. This approach enabled flexible A/B testing and cost or performance optimization while maintaining backward compatibility. Diego updated the test suite to validate the new logic and collaborated across teams to reinforce code quality. His work demonstrated strong skills in API and backend development, with a focus on maintainability and clear boundaries for future enhancements.
