Herraj Luhano
Worked on the mozilla/experimenter and mozilla-services/merino-py repositories, focusing on backend development and schema management. Delivered Firefox Labs Experiment Support within the Nimbus Experiment Framework by updating JSON and TypeScript schemas, introducing new optional fields, and implementing unit tests and fixtures to ensure regression safety and compatibility. This enabled more granular feature flag control for Firefox Labs experiments. In mozilla-services/merino-py, reverted metrics and logging changes for curated recommendations, simplifying the codebase and reducing data-collection overhead while maintaining core functionality. Utilized Python, TypeScript, and Pydantic, emphasizing robust testing, schema definition, and careful risk mitigation throughout the development process.
