Zhihao Ma
Worked on the inverse-inc/packetfence repository, delivering authentication and backend features focused on reliability, scalability, and security. Developed and enhanced NTLM authentication APIs using Python and Redis, implementing multi-process support with Gunicorn to improve throughput under heavy load. Improved configuration management and domain controller discovery by integrating Samba, while strengthening error handling and diagnostics for enterprise deployments. Contributed to deployment resilience through namespace isolation and centralized logging, and addressed machine account robustness with validation and timeout adjustments. Built an example HTTP authentication service in Python and Flask, updating documentation and resolving a content-length spoofing vulnerability to enhance integration and security.
