Dugas Enterprises, LLC - Atlanta, 1997-present
Owner and founder of Dugas Enterprises and the company’s sole employee. He has been operating the company and successfully delivering customer projects since it’s inception in 1997.
ITS Maintenance Projects - Secrco, Inc., 2012-present
Redesign and implementation along with ongoing operation and support of the ITS monitoring system deployed at GDOT originally in 2010. Integrated Nagios NMS with Maximo EAM for field device inventory and configuration as well as delivery of fault notifications as service requests. Expanded Nagios plugins to support device types and vendors deployed in Virginia for a second instance at VDOT.
Currently replacing the aging Nagios/MediaWiki solution with DugasEnt’s own MMS solution.
NaviGAtor ATMS Project - Georgia DOT Traffic Operations, 1997-2009
Led team of GDOT IT admins and contract developers. Responsible for administration and ongoing maintenance of NaviGAtor ATMS addressing numerous software defects and feature requests.
Redesigned and implemented TSS module for traffic data collection interfacing with numerous video, radar, and external detection systems. Implemented “gap filling” schemes for estimating missing samples to provide downstream consumers a complete and consistent traffic model. Included aggregation scheme to efficiently support sample data warehousing requirements.
Redesigned NaviGAtor’s video distribution and switching software to support multiple iterations of the field communication architecture. Supported migration from the original 90’s-era star topology to the multi-hub and spoke scheme in the 2000’s and then to the network encoder scheme currently employed.
Designed and implemented a novel scheme for ITS field device monitoring using the open-source Nagios NMS and MediaWiki. Provided NOC and field techs with detailed live and historical device status along with documentation of expected configs and connections. Developed numerous custom plugins to check the status and configuration of ITS-specific field devices. Able to automatically reconfigure field devices as they were deployed there by dramatically reducing the labor (and fault rate) for field techs. The system quickly became the master reference for NaviGAtor field equipment and the primary tool for fault isolation and troubleshooting.
Designed and implemented lobby-kiosk display system for NaviGAtor. A centralized content generator produced web pages detailing local conditions for hundreds of deployments. Solution included custom embedded Linux system, content sync system, and content players mounted behind flat-panel displays.
Designed and implemented the GeorgiaNavigator.com website providing live traffic maps and video captures to the public. Custom back-end content server collected and aggregated data from internal NaviGAtor subsystems and published XML data for partners. Custom video capture system interfaced with NaviGAtor video distribution system.
Implemented GDOT’s first successful version control and automated build systems for NaviGAtor. Migrated from proprietary Sun & HP to open-source tool chains (Subversion, GCC, autotools, make, etc.). Eliminated cumbersome #ifdef scheme employed by the TRW team and allowed the same code to build on all platforms.
ChillerCheck Project - Chillergy Systems, Inc., 2000-2008
Designed and developed a PalmOS application and HotSync conduit for collecting, verifying, and uploading HVAC chiller performance data. Included C/C++ mobile application, C++ Windows DLL, and ColdFusion API.
Serco, Inc. - Atlanta & Reston, 2014-2016
Capability Center Engineer, Transportation & Infrastructure
Development and maintenance of the maintenance management system supporting the ITS field maintenance service for VaDOT. Custom integration of open-source tools, industry-specific extensions, and commercial software to produce a unique “intelligent” MMS.
Workflow design and implementation in IBM Maximo for NOC and field maintenance business processes. Integration with Nagios NMS to create and update service requests. Nearly eliminated SLA violations due to “lost tickets” and allowed end-device operability levels to exceed 98%.
Added true CMDB features to IMMS for documenting field device configuration and connection details. Developed and integrated custom discovery and audit tools to automate CMDB maintenance.
Solution development for ITS and traffic signal maintenance proposals including cost modeling along with partner scope development and integration schemes.
Propagation Research Associates, Inc. - Marietts, 2004-present
Computer Engineer, Orthogonal Interferometry Radar
Architected and developed reference implementation of PRA’s innovative OI radar data and signal processing system in MATLAB. Developed real-time implementation in C++ using CUDA GPU processing. Included development of drivers and CLI tools for interfacing with Pentek high-speed ADC/DAC hardware.
Contract Computer Engineer, ETEC Data Collection System
Developed and maintained data collection software for PRA’s innovative ETEC system. Included Perl modules and programs to interface with Novatel GPS receivers. Deployed and operated hardware and software for a number of field tests of the system.
IT System Administration
PRA is half-owned by my wife. I’ve provided gratis IT sysadmin and support services since 2004.
TRW, Inc. - Atlanta, 1993-1997
ITS Systems Engineer, Georgia DOT ATMS
Sole designer and developer for the ATMS video control system software. Included communication server design and driver development for multiple CCTV protocols as well as VCR, matrix switchers, image multiplexers, projectors, and other system components. Innovative drag-and-drop UI for video switching and device control. Multi-instance collaborative video switch control system allowed routing of video through multiple regional control centers.
Designed and developed the GIS map application for the GDOT ATMS. Integrated commercial CAD package with custom UIs and other ATMS subsystems to display live graphical maps depicting the road network, traffic congestion, incidents, and field devices.
Built and integrated TRW’s ATMS demonstration system supporting customer education and business development efforts. Demo system also served as the development platform for GDOT’s ATMS video system.
Developed procurement specifications for field devices, communication networks, and control center equipment.
