Work History

Aug 2010 - ongoing Applications Programmer,  Bright House Networks, Riverview, FL BHNlogo

Design, code and test Openet Mediation and Rating system software using Openet-proprietary language (like TCL) and Oracle 10g SQL.  Used SQLPlus and Aqua Data Studio to develop and maintain database applications.  Wrote Java JDBC applications to support Production development and testing.

Created C# Windows Services data collection application for real-time Switched Digital Video server record collection using TCP.

Developed Java application using SAX, JAXB, JDBC, and Oracle for Y.1731 data collection application.  Also developed Oracle
PL/SQL stored procedures.  Developed RESTful web service to serve this data to customer-facing web portal.

Developed Java batch application to manage shipments to Bright House customers using Federal Express Web Services API.  Also used internal API
to update customer's account with the shipment tracking number.

As team member, developed Java Web-based Service Order management system using Java EE, Spring, Hibernate, and Struts, along with Oracle 11g.  Responsible for building business objects including Hibernate backend, along with HTML screen development using some Javascript and JQuery.  Also wrote about 30 reports using JasperSoft iReport write.  Wrote Python scripts for data migration.

  • Salesforce Projects
Created Git repo for storing our Salesforce production backups

Created Python scripts to migrate Big Machines configuration data between Salesforce organizations to allow multiple development teams to use Developer sandboxes 
and not have to use Full copy sandboxes.

Developed Salesforce Apex code to perform business logic, such as notifying construction when orders reach a certain state, copying construction survey data to 
related Installation records, and keeping track of Contract Rejection history.

Updated existing SOA integration code which extracts construction-related data from an internal BHN application and stores in Salesforce.  Required rebuilding SOA interface from new WSDL and remapping fields.

Updated Salesforce to support new workflow for Coax products to ensure that the work orders are relayed to the appropriate team.  This involved identifying
opportunities to set the appropriate Record Type and marking as Coax, as well as routing to new list views and reports.  

Developed code for a project to decouple creation of Installation objects from the Opportunity stage.  Previously, they were created automatically when the Opportunity
went to stage Proposed.  The new solution was to create a custom button to create Installations.  The fix also required Apex code changes as part of the decoupling.

A major project was completed for "In-flight Order Changes".  When customers had an order in place, as long as it was not completed, the users needed to be
able to modify the order for customer changes, including modify, add, change, and delete (MACD).  This involved creating a new copy of the Opportunity to
manage the new changes, but also "remembering" the old Opportunity for the items that were not changing, and for reporting purposes.

Nov 2009 - April 2010 Customer Service Representative, Fidelity Information Services, St. Petersburg, FL FISlogo

June 2008 - August 2008 Consultant, DSCI Corporation - Manchester, NHDSCI logo

  • Unix (Solaris), threads, Sockets, SIP, SS7

Redesigned and rewrote CNAM application for a CLEC. Application runs on Solaris and uses SCTP to receive TCAP requests for CNAM, which is looks up in a local MySQL 

database. If not found there, it performs a SIP lookup by sending a NOTIFY and waiting for a response from the SIP server.

Application was rewritten to use Pthreads package and to provide two worker pools of threads to do the MySQL and SIP lookups. I used the existing SCTP/SS7 code, but 

wrote the SIP thread code to build and parse SIP messages.

Developed a public API interface for the server as well as a client program to query statistics, set server operating parameters, etc. This code used UDP sockets.

Aug. 1990 - Nov. 1996 Principal Software Engineer, Teloquent Communications Corp., Billerica, MA.Teloquent logo

  • Windows, MFC, C++

Designed, coded and tested the TAPI interface (a MFC Extension-DLL) for the company's first object-oriented product, Open Agent. Other areas of responsibility included interface to Teloquent's IPC via Winsock (using CAsyncSocket). Development was done with Visual C++ 4.2, SourceSafe, and Rational Software's Rose product (methodology used was Booch's). Environment was Windows NT 3.51 development with Windows 95 target machines.

Designed and implemented the build environment for Open Agent using NMAKE and PERL to allow automated builds.

Other Windows development projects included an interface between Teloquent's Windows phone and two Windows pager programs, WinBeep and Notify! Interface program acted as a DDE client to both programs and would format and send the user a page with the (ISDN-provided) calling line ID, date and time if the phone was not answered in a pre-configured amount of time.

  • SCO Unix, C

Hired as employee number 15 to develop data network interface code for Teloquent' flagship product Distributed Call Center (DCC), a distributed Automatic Call Distribution (ACD) system based on ISDN. Was responsible for entire product development cycle, from design through system test. The Transport Network Interface (TNI) runs as a user process under SCO Unix and cooperates with the InterProcess Communication (IPC) server and library to provide transparent data connectivity over ISDN D-channel X.25. Transport layer provides ISO Class 2 functionality. TNI runs over a STREAMS driver providing access to an API developed by DGM&S. TNI also was ported to an embedded platform which runs on both Teloquent's ISDN phone set and on a Microsoft Windows Integrated Work Station (IWS). Embedded platform ran DGM&S real-time OS on an Intel 80188 CPU.

Designed and implemented an SNMP agent and MIB for network management of TNI.

Had sole responsibility for maintenance and enhancement of Unix STREAMS device drivers for Teleos Communications, Inc. B100 ISDN adapter and Teloquent hardware running DGM&S QSOURCE ISDN software. Drivers were originally developed for Teloquent by Lachman Associates, Inc. Ported initial MicroChannel driver to work with ISA bus. Enhanced driver by adding uploadable trace buffer for debugging.

Given responsibility in July of 1992 for voice process controller (VPC) to bring initial product to market. Responsibilities included debugging switch interactions and code cleanup. Product attained General Availability in January of 1993. The VPC acts as a CPE switch, managing the ISDN B-channels and utilizing the public switched network to transfer calls. Although functioning above the Q.931 layer and initiating network actions via a high-level API, network events are passed up directly. and thus extensive knowledge of Q.931 is required. Similarly to TNI, the VPC was ported to run in the agent set embedded environment. The VPC is the hub of a distributed processing system which manages protocols initiated by a central call routing process to transfer calls to customer service agents.

Served as project leader for ensuring that Teloquent's product ran on NI-1, including both DMS100 and AT&T 5ESS. Responsibilities necessitated trips to test sites at Ameritech (for 5ESS) and Bell Northern Research (for DMS100) and close work with switch designers. Added NI-1 codeset 5 support to Q.931 embedded code, and enhanced VPC to use NI-1 information.

SCSI controller was an NCR 53C94, with one on-board and three option-slot modules. Driver was tested and verified with DEC disk, tape and CD-ROM devices. Tape devices included DEC proprietary, Exabyte, and DAT formats.
