PROFILE

Jiahao Su

Over seven months, Damon Wang enhanced CI/CD pipelines and hardware integration across repositories such as ggml-org/llama.cpp, pytorch/torchchat, and linkedin/Liger-Kernel. He implemented automated build workflows for hardware-specific targets, notably adding Ascend NPU support and OpenEuler cross-architecture releases, using Python, YAML, and Docker. Damon refactored device selection logic in torchchat for broader accelerator compatibility and streamlined artifact packaging and release processes in llama.cpp. He also improved CI visibility and stability by updating README badges, fixing formatting-induced failures, and optimizing workflow diagnostics. His work demonstrated depth in DevOps, build automation, and continuous integration, resulting in more reliable, maintainable deployments.

Mar 1, 2026

March 2026 monthly summary for linkedin/Liger-Kernel. Focused on improving CI visibility for the Ascend NPU workflow and maintaining reliable CI monitoring despite permission constraints. Delivered a feature that displays CI status in the README, with the Ascend NPU test workflow executed in a fork due to self-hosted runner permissions, and results surfaced upstream for transparency. This reduced manual checks, improved cross-repo collaboration, and provided stakeholders with early visibility into CI health. Technologies demonstrated include Git, GitHub Actions CI, fork-based workflow management, and clear README documentation to communicate CI status to stakeholders.

Dec 1, 2025

December 2025 monthly summary for ggml-org/llama.cpp focused on CI/CD improvements and release reliability. Delivered targeted CI workflow optimization by removing the openEuler-cann build steps in the release pipeline and updating the CANN base image version, along with refining the container pull method to boost build efficiency and compatibility with the latest dependencies. Addressed pipeline quality issues by fixing error formatting, updating build.yml, and removing unnecessary zip artifacts to reduce noise and potential failures. These changes improved release stability, shortened cycle times, and ensured smoother deployments across environments. Demonstrated strong CI/CD execution, Docker/containerization, YAML-based workflows, and release engineering skills with clear business value in faster, more reliable releases.
