During April 2025, Liunia developed a feature for the aws/aws-cdk-rfcs repository, introducing L2 constructs to streamline Service Level Objective (SLO) configuration in AWS CloudWatch Application Signals. By leveraging AWS CDK and TypeScript, Liunia designed RFC-driven improvements that simplify SLO creation and management, reducing setup complexity for developers. The work focused on enhancing developer ergonomics and clarifying construct boundaries, enabling faster SLO adoption and improved observability reliability. Although no bugs were fixed during this period, the contribution demonstrated depth in cloud computing and software design, resulting in a more accessible and maintainable approach to SLO management for AWS users.
