PROFILE
Andrei Stan
Contributed to the cs-pub-ro/operating-systems repository by developing a parallel firewall assignment that introduces students to concurrency concepts using C and POSIX threads. The work included designing a producer-consumer model with a thread-safe ring buffer, providing both the scaffolding and initial parallelized code to help transition serial implementations to concurrent execution. Additionally, updated the course documentation to clarify plagiarism penalties, ensuring transparent and enforceable grading policies. The contributions focused on both technical depth—through parallel programming and ring buffer implementation—and operational clarity, supporting scalable student labs and reducing ambiguity in course policy enforcement through precise, well-documented rules and workflows.
