Recent Accomplishments:

 

·         Defined a SOA framework to expose service provisioning for a wireless carrier, exposed a NetworkOrderService as the public interface for network order provisioning.

·         Decreased overhead by approximately 40% by implementing an application using the Broadworks VoIP switching platform to provision services, manage DIDs, bill and audit both ISP and VoIP customers.

·         Implemented an IVR system using VXML and CCXML to allow users to reserve or cancel a class.

·         Provided technology leadership to bring up speech-recognition application to enhance existing VoIP services, speech-enabled auto-attendant application for existing customer base to increase average revenue per user.

·         Developed an audio mining application using the Philips and Nexidia speech-recognition software development kits; application automated monitoring of live, recorded conversations and callback implementation. Reduced overhead cost by 75% to increase profitability.

·         Defined, implemented a software framework for a switching platform within the Microsoft .NET framework. Formulated SS7 and SIP message processors to manage the signaling required between network domains/devices.

·         Defined/Architected next-generation voice services platform and Implemented the core call control, routing engine and location server using a SIP-based messaging framework; IETF SIP Draft.

·         Deployed a Voice-Activated Conferencing service using VXML browsers from both Nuance and SpeechWorks as components of the platform architecture; network deployment on the Voxeo and BeVocal networks.

·         Developed and led Bell Atlantic Certification of world's first SoftSwitch application supporting voice/data offload within allocated time constraints; successful testing contributed significantly to company buyout (Level3 buyout of XCOM).

·         Developed messaging objects for SoftSwitch platform to support Data/Voice switching; team member of patent on call processing engine; largest revenue source for Level3 managed-modem deployment $0.75Bil.

·         Implemented SS7 Communicator/Gateway on Unix Platform to support SS7 network interface; call control application to switch data/voice communications.

·         Defined a protocol converter from ISDN signaling to SIP-based signaling; used RTP/RTCP for media transfer; interface to Cisco/Lucent network devices to terminate phone calls satisfying throughput and memory requirements.

·         Developed real-time FraudService for internet electronic software distribution (ESD) application; C++ architecture with bridge pattern implementation; delivered on time with performance objectives satisified.

·         Designed and implemented a mathematical library for a real-time embedded signal processor within allocated schedule; employed object-oriented design methodology.
