Principal Engineer -- Ciena (Mar 2008 - April 2025) Managed cross-functional teams across hardware, software, and testing to deliver 15 major control plane software releases for optical DWDM platforms, deployed across hundreds of global customers. Received multiple awards for key contributions to the company’s line of products. Contributions include:

-Architected and implemented PNNI-based optical signaling and routing protocols (OSRP), improving network scalability for 10,000+ node deployments

-Optimized database synchronization between network elements, reducing recovery time from 40 to 8 minutes in large-scale networks

-Developed critical network performance monitoring and safety protocols, preventing high CPU utilization, reducing packet retransmission, and resolving system bottlenecks

-Worked on control plane stack scalability across multiple product families, allowing customers to deploy larger networks (upto 3x larger post-improvements) Patents

-A bandwidth de-fragmentation algorithm for mesh topologies, enabling automated service restoration

-A conflict resolution system for bandwidth allocation in linear networks, post-fiber failure

-A crank-back algorithm, improving routing decisions through connection rejection analysis
