Windows Server 2003 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. |
