PROFILE
William Chang(張仲威)
Worked on the Canner/WrenAI repository, delivering end-to-end features that advanced AI-driven analytics and platform reliability. Built and enhanced RESTful and GraphQL APIs using Go and TypeScript, enabling natural language to SQL workflows, real-time communication, and scalable AI content pipelines. Led release management cycles, coordinated multi-repo versioning, and implemented robust configuration management with Docker and Kubernetes. Addressed security compliance by remediating vulnerabilities and upgrading dependencies, while improving CI/CD workflows for deployment stability. Contributed to both backend and UI development, integrating AI services and refining error handling, which improved user experience, release traceability, and the security posture of the product.
