Current Security Clearance – Secret acrhwg@r.postjobfree.com Summary of Experience: Lead position which requires self-starting and initiative to work independently. It also requires extensive simulation/modeling experience to understand very high level modeling concepts (Groundwater Hydraulics dealing with applied hydrological concepts such as overland flow, surface water-canal interaction, etc.) utilized in the US Army Corp of Engineers

(USACE) modeling software as well as constructing plans to incorporate USACE modeling strategy and identify/design major software tasks to assist critical USACE projects related to Everglades Restoration. The position requirements include the ability to create and modify FORTRAN, C, and C++ based models that include functional, operational and hydrological processes. This involves developing high performance algorithms requiring math/physics/engineering skills. Critical project responsibilities include designing, establishing requirements, developing software, and integrating data analyzers and search engines with existing deterministic models that provided real time guidance of existing and proposed hydrological processes.

Report to Al Yanick 561-***-**** - Info Systems & Global Solutions - Task Lead Programming and Modeling Skills:

• Incorporate new C++ templates into USACE modeling software to incorporate new hydrological features. This required utilizing Standard Template Library concepts to store, retrieve, and manipulate data.

• Supported the Everglades Restoration Project by recommending new software which required thinking outside the box. My responsibilities included constructing concept documents and developing large scale FORTRAN systems

(over 35K lines) that dovetailed the existing FORTRAN modeling software so that new methods of evaluating modeling results may be achieved. This software was also used to evaluate the accuracy level and quality of internal processes, verification checks, etc. on different compilers in support of evaluating the impact of porting software from the existing FORTRAN compiler to proposed FORTRAN and C++ compilers.

• Reverse engineered existing computerized hydrological processes to provide critical information to the business groups in language that they would understand. With the models being very complex, and changes made year after year, the model algorithms needed to be deciphered for those individuals who are new to the model, as well as those who have worked with the model for years,

but are not aware of upstream factors which may affect the outcome of their individual portion of the model.

• Software development includes self-testing routines that traced and debugged software executions. Software design also includes report generators and tracing routines that identified processing problems as part of the system to enable testing and perform diagnostics to isolate program bugs, execution failures and incorrect input.

• Constructed advanced computer language linking methods that enabled the modeling software to compare different mixes (combinations) of canals, reservoirs, structures, etc. which is generally not available in most hydrological software packages. This advanced item required developing software self-testing routines that traced and debugged hydrological processing routines so that the

modeler would be able to accept the results with confidence.

•Other assignments also involve converting FORTRAN programs to C++ software. Job duties also include utilizing UNIX/LINUX platforms and constructing both Korn/Bourne shell scripting and makefiles. Air Traffic Control Experience (FAA Air Traffic Control System Command Center):

• Designed, coded, and processed UNIX (Bourne/C Shell) script files to orchestrate simulation testing on live data scenarios utilizing Solaris platform to verify software design changes and ensure correct avionics communications in support of the Air Traffic Control CTAS (Center TRACON Automation System) TMA (Traffic Management Advisor) system.

• Module testing included CTAS communication, trajectory synthesizer, route analyzer, input source manager, TMA(TGUI/Timeline), FAST(PGUI/plan view), dynamic planner, etc.

• Provided C++ code inspection of vendor Air Traffic Control software modifications using Solaris UNIX platform with FAA pass or fail authorization.

Prior Microsoft Windows C++ software skills:

• Provide detailed maintenance and enhancements for an online dispatch priority real-time system, which allows multi-workstation controlling on-going incidents using a complex property page and dialog panel design.

• Developed solutions to fix complex problems ranging from TCP/IP sockets, COM interfaces, and customize GUI architecture design changes.

• Provided tracing routines within the application (comprising 600+ classes, multithreading, COM, and 3 separate executables) to track messages from and to the gateway, which uses OS/2 technology and AS400 equipment.

• Experience include administering software version control using Visual Source Safe, providing software CD releases to clients using Install Shield, and constructing documentation.

• Redesigned SDK application to accommodate WIN2000 changes in COM multi-threading. Modified coding process to fix functionality that was rendered obsolete due to WIN2000 design changes in Microsoft software.

PRIOR MODELING/SIMULATION and QA/QC program experience:

• Director of two groups (staff of 12) which developed and supported on-going statistical modeling/Monte Carlo simulation of vehicle fleet operating/financial expenses and vehicle QA/QC programs sold to FORD/GM/Chrysler.

•Supported corporate strategy by designing and developing deterministic and statistical financial engineering software which incorporated revenue management of risk, profit performance, and minimization of taxes.

•Provided on-going operation research studies that improved organizational operating processes of requisition and invoice flow, treasury functions, and company product revenue recognition procedures. PRESENTATION SKILLS:

• Project completion required detailed power point presentations, EXCEL listing of project tasks, milestones, flowcharts, etc. to explain in detail the successful completion status of the total project process. This was required to obtain software certification from the USACE/South Florida Water District control board to enable new development and

modifications to be placed into production status. QC/QA SKILLS

• Management/Client experience working with FORD/GM/Chrysler QA/QC processes based on real time defect analysis which utilized Weibull and other distribution patterns

• Directly worked on site with vendors to identify root cause problems, corrective and preventive actions, and evaluate hardware compliance based on engineering specifications. Constructed stress analysis and identified failure due to frequency harmonics on turbine blades to support mechanical engineering. Developed and computerized a QA inventory/receiving and inspection system to track developmental hardware for Air Force jet engines.
