Vyshak Haridasan developed and maintained robust IP allowlist and blocklist management features for the ZCSOC/az_zal_blocklist repository over five months, focusing on access control and network security. He implemented batch update mechanisms and data refresh workflows, enabling efficient, auditable updates to IP lists without altering core logic or causing downtime. Using skills in configuration management and network administration, Vyshak ensured consistent propagation of access rules across components, reducing manual intervention and operational risk. His disciplined use of Git for traceable, incremental commits enhanced auditability and rollback safety, resulting in a maintainable, policy-driven approach to network perimeter defense and governance.
