SIP Squared offers cellphone retailers a single platform to provide Text,

Voice, and Data over the cellular network from any of the major carriers in

the US. We built a platform from scratch to communicate with AT&T, Sprint,

Verizon, and T-Mobile to communicate customer preferences and plans for

their cellular service so that customers may modify their service

automatically without having to communicate directly with their provider.

As Lead Engineer, I created a lot of this software on a low level in Linux

using Java, webservices, and APIs, and also ran a team for design on the

front end facing customers.

telephony. Clients included Intel, Aculab, Glenayre, Think Engine

Networks, Commetrex, Brooktrout Software, and Pivotech. Responsible for

managing the engineering department of up to six software engineers, for

several simultaneous clients. Each client had different manpower and

budgetary requirements that needed to be managed. Project management

included client liaison, proposal generation, architecture and design,

project reports, testplan development, and customer deployment. Almost

every project required C++ and object oriented design and architecture

development, many times for multiple object interaction, and multiple

application interaction. Technologies included T1/E1/ISDN. Also,

developed telephony applications and middleware using VoIP protocols (SIP

and H.323) between Linux and Windows systems. Most of the VoIP work was

low-level, driver-level SIP stack development for automated calling.

modules to allow plug-in grammars for applications.

Senior Consultant/Software Engineer Intergen Group

Dunwoody, GA

June 1999 - September 1999 for Melita

International, Inc.

Maintenance engineering on predictive dialer product for high-profile,

telephony-specialized customer issues. Issues ranged from conferencing,

ISDN protocol errors, loop-analog errors, and T1 AB bit protocols. Windows

NT, and IBM AIX were the operating system platforms. All code was object-

oriented C++. Some engineering required redesign of C++ objects and

applications. Dialogic and Aculab telephony products were used, in SC-Bus

mode.

Senior Consultant/Software Engineer SCM Group

Dunwoody, GA

Jan 1997 - August 1998 for Syntellect, Inc.

Responsible for architecture, port, and programming of Syntellect's

predictive dialer telephony server, from DOS to UnixWare. Expanded agent

capacity from 24 agents per telephony server to 72 agents per telephony

server, with outbound lines growing from 48 to 144 channels. In addition,

the new server was ported to the SCBus, and T1 and E1 ISDN abilities were

added. A more robust software management interface was added to help debug

customer problems remotely and upgrade software, limiting the need for

travel to the client destination for customer support issues. Software was

mixed C and C++; basic telephony modules used C APIs while the applications

themselves used C++ object oriented development. Telephony was

accomplished using Dialogic telephony boards and Aculab telephony boards.

Senior Consultant/Software Engineer SCM Group

Dunwoody, GA

Sept 1996 - December 1996 for Melita

International, Inc.

Converted Melita's CO Simulator to work from it's original AusTel E1 ISDN

PRI protocol to work with AusTel, ETS300/Net5 E1 ISDN PRI, USA NI2 T1 ISDN-

PRI, T1 D4 E&M, T1 D4 Loop Start (FXO/FXS), and 8 channel Analog, all on

the same platform of hardware and software. This allowed a more flexible

and time-saving CO simulation platform for a wide variety of ISDN and

standard telephony support. Also converted a recording tool to establish

call progress events on several platforms and protocols, including AusTel,

ETS300, and NI2. This development used Aculab's T1 and E1 ISDN PRI cards

as a front-end with Dialogic D/320SC cards as the DSP back-end for the ISDN

protocols, Dialogic DTI240/SC front end with D/320SC cards for the T1 D4
