PROFESSIONAL EXPERIENCE

Oasys, Huntsville, AL

2014-2015

Software Analyst

Software Analyst with the contract to assist the Software Engineering Directorate.

• Web development in Java, Spring, NetBeans, GWT, JavaScript, Web Services, and Angular

on Windows systems.

• Using the R programming language to analyze maintenance data.

TEK Systems, Huntsville, AL

2012-2013

Software Analyst

Assisted Intergraph Corporation as a Software Analyst on the PPM project.

• Converted many components from Visual Basic to C++, getting closer to the goal of

begin able to process large drawings in a 64-bit process, enabling the customer to

process larger drawings. Used Visual Studio for this and for C# .net components. Used

Coverity to analyze source code. Source code stored in TFS.

• Added many features to the project, satisfying customer's requests.

• Created tests to guard against regressions, thus avoiding future bugs.

Colsa Corporation, Huntsville, AL

2006-2011

Software Analyst

Designed and wrote software for NASA EHS (Enhanced HOSC System) project, PIMS

(Payload Information Management System) project and the PPS (Payload Planning System)

project.

• Enabled users to securely communicate over the Internet with NASA's database

containing mission-related documents and procedures, with other NASA sites, and FTP

servers.

Oracle

Python

Secret, 2014-2015

• Utilized Java (using plain Java and Enterprise Java Beans running under JBoss), C, and

C++ on Irix, Solaris and Linux systems and utilized CORBA, Java RMI, and the FTP protocol

for remote communications.

• Stored software in the ClearCase version control system.

• Created the PPS reporting function to output the status of a sequence of even, letting the

managers discern the situation easily.

• Added refinements to the PPS event sequencing, making the software more closely

matched to the real-world requirements.

• Contributed many components of PIMS, so that information relating to Space Station

Operations could easily be stored and retrieved.

• Managed the integration between PIMS and the main components of EHS, using

CORBA as the medium so the two sides could communicate easily.

Computer Sciences Corporation, Huntsville, AL

Software Analyst

Same as Colsa (same contract).

bd Systems, Huntsville, AL

Software Analyst

Same as Colsa (same contract).

Teledyne Brown Engineering, Huntsville, AL

1985-1998

Software Analyst

Created software to tie the Missile Defense Data Center to the alpha phase of the Virtual Data

Center, a project to use Web technology to enable analysts to remotely search, browse, analyze,

and retrieve data.

• Created the local database, programmed the Web server, and wrote components so that

the three nodes of the distributed Missile Defense Data Center would seem as one to the

users.

• Wrote extensive software to retrieve, display, and output data derived from Missile

Defense programs.

• The software was written in Fortran, C, and C++, on a Solaris system, with embedded SQL for

Ingres database access and Oracle OCI for Oracle database access.

• Programmed for several simulations: JTIDS Operational Performance Model (JOPM),

Network Assessment Model, (NAM), Communication Simulation (COMSIM), and Extended

Air Defense Simulation. Software was C on an Irix system.

• Programmed event management, digital terrain, radio connectivity computation, and

graphics (using OpenGL) to help create a faithful model of the situation to improve the

customer's ability to plan operations.
