Over eight months, Mike Sarahan engineered robust CI/CD telemetry and workflow automation across RAPIDS repositories such as rapidsai/shared-workflows, rapidsai/rmm, and rapidsai/docs. He streamlined telemetry collection and reporting by integrating OpenTelemetry, refining GitHub Actions pipelines, and consolidating data processing logic using Python, YAML, and Bash. His work reduced infrastructure complexity, improved build reliability, and enabled actionable observability for development teams. Mike also authored comprehensive documentation to guide telemetry integration and package publishing, ensuring maintainability and clarity. By standardizing workflow patterns and automating artifact validation, he delivered scalable solutions that accelerated feedback loops and reduced maintenance overhead across projects.

June 2025 (2025-06) monthly summary for rapidsai/shared-workflows: Stabilized CI telemetry workflow reliability by removing conditional execution based on run attempt numbers; telemetry setup and upload now run only when TELEMETRY_ENABLED is true, and GH_TOKEN is consistently available for telemetry actions. The fix reduces telemetry flakiness and improves data quality across CI runs.

February 2025 focused on simplifying telemetry-related workflows, accelerating CI, and extending telemetry visibility across repositories. Delivered key features that remove legacy telemetry wrapping, establish robust telemetry artifacts handling, introduce caching for dependencies to reduce build times, and refactor telemetry pipelines for clearer metrics. Telemetry collection and summarization are now integrated into raft CI/CD with conditional execution, enabling better KPI tracking while keeping builds fast and reliable. These efforts reduce complexity, lower maintenance costs, and improve data-driven decision making for release readiness across rapidsai/gha-tools, rapidsai/shared-workflows, and rapidsai/raft.

December 2024: Delivered telemetry-driven workflow improvements across rapidsai/shared-workflows and rapidsai/rmm that reduce infrastructure, simplify maintenance, and preserve observability, delivering clear business value through CI/CD optimizations and data processing consolidation. In rapidsai/shared-workflows, introduced conditional telemetry execution behind TELEMETRY_ENABLED in GitHub Actions, streamlining telemetry setup and replacing redundant steps. This work is captured in commits dcd3a97e26c9e433728cc64ad5afc048f1415ec8 (gate telemetry summarize behind TELEMETRY_ENABLED env, #270) and 3313dce51b2cfea4601c30a986cd5980087fe2c1 (remove telemetry summary from shared-workflow jobs, #269). In rapidsai/rmm, simplified telemetry processing by removing certificates and consolidating summarization into a single job, updating the workflow to reduce infrastructure requirements, as shown in commit 1af03eb55ce51a376c3df2dc0cdf3c81738b2dd6 (remove certs and simplify telemetry summarize, #1750). Overall impact includes lower infra footprint, faster pipelines, easier maintenance, and sustained telemetry visibility. Technologies demonstrated include GitHub Actions, YAML workflow optimization, environment-driven feature flags, and data processing consolidation.
