During a two-month period, Betty contributed to the Netflix/mantis repository by delivering four backend features focused on system modernization and reliability. She upgraded the publish workflow to Java 17, improving security and enabling use of modern Java features through Gradle build automation. Betty enhanced observability by upgrading Spectator and Archaius libraries, adding job identifiers to logs, and refining metrics tracking for job and worker failures. She refactored job submission validation into a utility class, introducing resource constraint checks and better error handling. Her work, primarily in Java and Groovy, emphasized maintainable software architecture and robust dependency management without introducing regressions.
