Wang Weijie developed and delivered a new official manylinux_2_38 Docker image with LLVM 15 for the Loongson-Cloud-Community/docker-library repository, focusing on streamlining CI and build environments for Loongson projects. He implemented a Dockerfile-based build system that sets up a cross-architecture toolchain, including Ninja and LLVM compilation for LoongArch, and automated the build and publish workflow using Makefile. By enabling reproducible, scalable CI pipelines and supporting cross-compilation, his work reduced setup time for developers and improved integration into existing workflows. The project leveraged skills in Docker, Linux, and build systems, demonstrating depth in infrastructure automation and developer tooling.
