EXPERIENCE

CISCO SYSTEMS, RESEARCH TRIANGLE PARK, NC

Software/QA Engineer IV, SDU Cloud Systems

Aug.’10–Present

Cisco SDU (Systems Development Unit) charter is to create, validate and market architectures and end-to-end

solutions for service providers and large enterprises. Currently working on Cisco’s InterCloud fabric hybrid

cloud solution with multiple public cloud service providers (e.g., AWS, Azure, DiData, etc.).

• Led requirements gathering for Cisco’s InterCloud fabric solution in collaboration with engineering and

marketing teams. Developed system topology integrating Service Mesh with cloud components and created

detailed validation plan for testing solution around two use cases – capacity augmentation and application

development & test.

• Validated Disaster Recovery as a Service (DRaaS) 2.0 solution for enterprise and service provider customers

over layer-2 extension (OTV& LISP) between data centers using InMage Scout to provide service backups.

• Built, configured and deployed Virtualized Multiservice Data Center (VMDC) 3.0 in Cisco’s Cloud

Validation Facility (CVF) to enable customers to gain hands-on experience with technologies and solution.

The solution introduced FabricPath, instead of Spanning-tree, which offered better convergence performance

and higher layer-2 link utilization.

• Identified configurations for various compute and storage components, network elements (switches and

routers) and service appliances (load-balancer, firewall) to develop VMDC3.0 solution architecture in

collaboration with marketing team and solution architect. Delivered Cisco validated design along with design

implementation guide to enterprise and service provider customers.

• Designed and validated VMDC 2.1 service orchestration solution using BMC’s Cloud Lifecycle

Management (CLM) 2.1 software in partnership with BMC. Service orchestration enabled service providers

to deploy Infrastructure-as-a-Service (IaaS) from CLM 2.1 portal within minutes.

Software/QA Engineer III, ECATS

May’08–Jul.’10

Cisco ECATS (Enhanced Customer Aligned Testing Services) charter is to replicate customer networks in the

lab and validate architecture, design and technologies. As a foundational engineer, played a key role in growth

and expansion of the ECATS group within Cisco.

• JP Morgan Chase (JPMC): Collaborated with JPMC team and Cisco’s Advanced Services team in

understanding client’s network architecture and upgrade requirements. Developed test strategy and test bed

topology to validate interoperability of JPMC’s campus and data center network upgrade from IOS to

modular image. Delivered test report and hosted onsite visit for client to gain hands-on experience with

network operation. Demo was key in winning JPMC’s confidence and business in upgrading Cisco IOS.

• Citigroup: Conducted functional test and performance validation of SXH4 modular image for Citigroup’s

Global Shared Services (GSS) environment. Identified and resolved several software defects to help improve

product quality. This led to acceptance and deployment of modular image in Citi’s production network.

Software/QA Engineer II, NSITE

Aug.’04–Apr.’08

Cisco NSITE (Network Systems Integration and Test Engineering) mission is to perform system level test of

complex solutions spanning multiple technologies and products to accelerate successful customer deployments.

• Developed system topology and test plan for validating Intelligent Service Gateway (ISG) solution for

service provider broadband access network using Cisco 7206/NPEG2 router, Broadhop SME (portal & policy

server), CAR (AAA server), RSIM (Pre-paid server) and CNR (DHCP server). The solution enabled service

providers to take direct control of resources and network characteristics to deliver next generation services.

The solution was successfully deployed in a number of service providers’ networks.

• Performed quality assurance testing of multi-service delivery network solution for voice, video, data and

Metro Ethernet business services using different class of services (CoS) over same VLAN. The core

topology was built using GSR12000 platform with MPLS traffic engineering tunnels and FRR (Fast Reroute)

for node and link protection.
