Worked on the infiniflow/ragflow repository to deliver a cross-architecture Docker Sandbox installation, focusing on improving deployment reliability for both ARM and x86_64 platforms. Addressed a specific CLI error affecting ARM CPUs by updating the Dockerfile, enabling seamless multi-architecture support and reducing installation friction in heterogeneous environments. Applied skills in containerization, DevOps, and Dockerfile development to enhance compatibility and usability for diverse customer deployments. The technical approach centered on multi-arch build strategies and cross-platform packaging, resulting in faster onboarding and broader adoption. This work demonstrated depth in Docker workflows and contributed to more consistent, reliable Sandbox deployments across varied systems.
