Yiannis developed a unified Policy Decision Point (PDP) plugin for the IBM/mcp-context-forge repository, focusing on orchestrating access control decisions across multiple policy engines. By integrating policy-based access control and plugin architecture, he addressed the complexity of managing cross-engine policies and strengthened the overall security posture. The solution standardized access decisions, reducing management overhead and improving flexibility for multi-engine environments. Yiannis utilized Python for backend and API development, demonstrating skills in security and policy management. Although the work spanned one month and involved a single feature, it reflected a deep understanding of multi-engine orchestration and commit traceability in enterprise systems.
