OBJECTIVE:  Software Engineer/Project Development Manager with demonstrated strengths in Software Systems Development, Distributed & Client/Server Networking and Technology Deployments/Ports will implement, manage and integrate military tatical C2 software systems to meet mission functional, security and quality objectives related to DBST & ABCS. This candidate has hands-on experience installing and configuring JCATS, having managed and participated in BBS and Musio exercises at the AMEDD simulation center where he has acquired passing familiarity with HLA application protocols. The candidate also has a computer science and systems design degree which will enable detailed understanding of DIS, SIMNET, ALSP, HLA and other similar application level protocols. He has worked as a C++ software developer and enjoys the challenge of working with complex object oriented simulation systems and using his technical knowledge and diagnostic abilities to accomplish business objectives. He has extensive practical experience with standalone and distributed systems using numerous networking technologies, but primarily TCP/IP on Ethernet using CISCO routers. He is well versed in shell scripting, computer operation support procedures and system administration of Microsoft Windows, Solaris, Linux and other Unix style operating system workstations. The candidate's networking expertise entends to having developed Virtual Private Networks using encryption beyond the level of DES (Defense Encryption Standard). He understands how to organize and configure the staff, networking and computing infrastructure needed at the AMEDD Simulation Center so as to implement the simulation components of JDLM, ABCS, ATCCS and similar architectures dictated by DoD objectives. This candidate welcomes working with trainers and technical counterparts at other locations which understand such systems as MAIS, MILES, SAWE, CTESS, DITS, FBCB2, EADSIM, FireSim XXI and SIMPLE in creating a coherent and interoperable medical training system accessible on site as well as via NIPRnet. The candidate's command of SQL, relational database design and query language combine with his communications/networking and programming abilities to uniquely qualify this candidate to focus on implemeting solutions and establishing best practices.
