Throughout my tenure played a key role to maintain Time Warner Cable's national leadership position in service excellence and network availability.•Earned several MVP awards for leading the design, launch and buildout of TWC's GIA initiative. GIA is an effort that required Voice network build and migration of TWC digital phone subscribers from existing Sprint and MCI network to TWC owned and managed network. Benefits are not only limited to the financial and strategic benefits (huge significant bottom line savings, quick launch of new products and enhancements which are not possible under existing contracts, geographic network redundancy and more control of business, strengthened customer confidence) but also provided great benefits for technological innovation & new opportunities. •Independently designed SIP interworking specifications, acceptance test plans, prepare and built test environment lab to perform interoperability testing with various peering partners (T-Mobile, AT&T, Verizon, Comcast, Cox, Level 3, Neutral Tandem, Telecom New Zealand, KGB, Intrado etc.)•Actively involved in RFP process for vendor selection, prototyping solutions, developing ATP and evaluating NextGen technologies and networks for voice core. Hands on working experience with products from industry leading vendors (Cisco, Nokia, Alcatel Lucent, Oracle, Acme Packet, Arris, etc.) and core telephony products (IMS Core, Telephony App Server, Session Border Controllers, Access Tandem, Softswitch, Media & Trunking Gateway, STP/ITP, PRI and SIP gateways, eMTA).

• Solely responsible for envisioning and architecting, design and system requirements, leading development and performing integration and acceptance testing of NextGen Automation Orchestration platform "iDATS". Successfully lead an onsite and offshore team in Agile like environment for software development and effectively released the solution in 6 months. This tool revolutionized integration testing and significantly improved patch and software release process. iDATS framework interwork (python API) with GLCom for analog call generation, provisioning systems (Web Services - soap XML/REST) for subscriber provisioning, billing systems for CDR processing, Empirix XMS for call trace, TestLink - web based test management system (Java API), for test management and updating test results and logs.• Architected and developed Voice over IP platform based on IMS supporting Residential and Business Class services including Digital Phone, PRI & SIP Trunks, and Softphone. Successfully lead a dynamic team and integrated Alcatel Lucent IMS TAS with Nokia IMS core and migrated 1.5 millions customers in a year.• Designed and simplified complex dial-plans, in-switch translation and routing tables of access tandem, TAS, CMS and IMS based on NANPA, LCA and LERG information for quickly and efficiently launching Digital Phone service across 35 US states.• Developed white papers for complex line level routing solutions for N11 service using ENUM and directory service, tested in the lab and implemented in production for regulatory compliance.• Managed and established relations with vendor and ops team to streamline process for planning major upgrades, maintenance releases, feature enhancements and hot fixes and stay ahead of the curve.• Provided methodologies for successfully migrating 6 millions subscribers from traditional VoIP network to geographic redundant and fault tolerant IMS core network.
