  Intelligent Traffic Director (ITD): Intelligent, hardware-based, multi-terabit solution that allows you to build a scalable architecture for Layer 3 and Layer 4 traffic distribution, load balancing, and redirection. ITD was the winner of the ‘Cisco Pioneer Award 2015' and ‘Interop 2015'. Excelled as one of the core Team Leads to design and develop multiple critical features of ITD. Helmed a diverse, high-performance team to design and implement various features on the ITD roadmap like multiple ‘fail-action' algorithms, and convergence optimizations. Guided flawless deployment of the feature and expertly supported it through production for industry-leading customers like Korean Telecom, Bank of America, Vodaphone, etc. Played an integral role in cross-functional effort to procure a multi-million order from Korean Telecom through multiple rounds of feature enhancements, scaling ITD from 32 to 128 nodes, and convergence improvements. Worked with Marketing to get the requirements, design and develop required features, and deploy ITD as their Data Center Load Balancer for Reliance. ITD was the first feature to be developed and delivered in Agile, as a first pilot program in Nexus platform. Streamlined Engineering development process through impeccable integration of Unit-Test-Automation, Regression sanities and code-reviews, driving a 50% reduction in incoming bugs. SmartChannel: Hardware-based solution using Layer 2 Vlan ACLs to load balance traffic at hardware level. Orchestrated and implemented SmartChannel on both Nexus 7K and 9K Managed development of feature as “Proof of Concept” for Go Daddy Designed and modified SmartChannel feature to become a pure software feature by making it platform-independent, which can be deployed on any switching platform with minimal effort. Used Rally to more efficiently assign, track and manage projects and timelines through Agile methodology.

• Technical Leader

  • 2010 - 2015

  Lead, designed and developed multiple Layer 2/3 features on networking protocols including STP, VLAN, VPC, VTP, Fabricpath, Private Vlan (PVLAN), etc. Development experience in numerous other areas like L2 gateway STP, Phy-Port VPC, Fex-VPC, etc.  Played a pivotal role in increasing Customer Satisfaction by coordinating with customers to understand issues, recreate topologies, try out fixes/workarounds on production networks and discuss future enhancements.  Debugged and resolved issues causing memory corruptions, leaks, crashes, and packet loss Lead of Spanning Tree Protocol (STP) Component: Managed team of three to develop vital STP features and enhancements; wrote complete functional and design specifications, as well as test plans. STP Scale: Increased logical port number support in N7K for both RPVST (16K) and MST (300K) mode through multiple custom-tailored design and implementation changes. VPC (Virtual Port Channel) Scale and convergence: Chosen as member of VPC Scale Architecture team to improve scale and convergence; increased number of VPC legs to 750 and convergence level brought down to 1 second on failure recovery. Vlan Trunk Protocol (VTP) version 3: Enabled VTP v3 on Nexus 7K switches and expertly implemented MST configuration as the very first non-Vlan application to use VTP. VXLAN on VPC: Coordinated with team to implement VXLAN in N7K; focused on STP support in VPC environment. Overlay Transport Virtualization (OTV): STP Support for Cisco's industry-first technology that extends L2 applications across distributed data centers. Vinci on N7k: Vinci is a DataCenter fabric built on a spine-leaf topology that provides optimal connectivity at Layer-2 and Layer-3. Added STP Support for specific vinci based interfaces (VSI). ‘STP Lite': Designed and implemented a ‘lite' version of STP on MDS/FCOE platforms for faster convergence, including single-sourcing different flavors of STP code from N5K and N7K platforms into one.
