EXPERIENCE

Sr. C++ Software Engineer

Confidential

• Working on the Intelligent Network team where I am using C++11, STL, Boost, XML, REST, JSON, Eclipse, QPID (AMQP), LibESMTP, SQL, Vertica, libCurl and Twilio libraries on Linux.
• Currently I am designing a multithreaded C++ application that will query the status of hundreds of thousands devices using an in house SNMP library.
• It will need to handle 50,000 SNMP queries per second on each core.
• Last year I designed and built a multithreaded application that receives messages through a QPID broker.
• Each message is filtered and any embedded embellishments are substituted with values retrieved from an Oracle database.
• The messages are then sent on to recipients via SMTP, SMS (via Twilio) or REST. All email messages are recorded into a Vertica database.

Sr. C++ Consultant

Confidential, Denver, Colorado

• Working with Visionics Facial Recognition SDK, OOD/P, Visual C++, MFC and DirectX sound on Windows 2000 I built a facial recognition system, which allowed the user to manage a facial database and to run video surveillance.
• While in video surveillance faces were captured through a video camera and compared to faces in the database.
• If a face was identified as a known foe then a signal was sent via RS - 232 to a switch causing a digital video recorder to alarm.

Confidential

• Confidential was a startup, which would have provided weather alerts and schedule change alerts to airline travelers.
• Using OOD/P, C++ on Linux and Windows 2000 I built a near Real - Time (asynchronous event handling) multi-threaded X.25 BATAP Receiver (BReceiver).
• BATAP is the airline industry standard protocol used to send passenger name records (PNR) across X.25 networks.
• BReceiver ran 24/7 and communicated with a X.25 EiconCard, which in turn was connected to a FRAD.
• BReceiver parsed each BATAP and extracted the PNR from the BATAP, which then was sent via a TCP/IP socket connection to the PNR Parser.
• I also built HTML pages, which allowed the user to enter FAA alert messages.
• I built a servlet, which received the FAA data from the FAA pages and with SQL through JDBC inserted the data into the FAA message table in a Postgres database.

Confidentia

Using OOD/P, Java servlets and MySql within a Linux environment I helped build a web site that provided a 24/7 shopping cart environment where our customers could use a Wizard to setup their own online store. Here I built servlets, modified existing servlets and built web pages using HTML and JavaScript.

Confidential

• Using Java Servlets and JSP s within a Windows NT environment I worked on a research and development task where we designed and implemented module components to be used for future ecommerce solutions.
• I helped research and implement the validation that was needed by the various fields found within each component.
• On another project, I built using JSP s, a sign - in page and a billing page.

Sr. Software Engineer

Confidential, Louisville

• Using C/C++, Oracle, SQL*PLUS and PL/SQL I designed and implemented changes to a large 24/7 near Real - Time (asynchronous event handling) distributed UNIX (HP, Confidential, DG) system.
• This system facilitated communications between the various Confidential hospital applications and user interfaces through TCP/IP sockets.
• I also developed C++ programs to check the database for current facility and department messages and displayed them to the user.
• It consisted of two processes, MotdOverLord, which listened for connections on its TCP/IP stream socket and the other process, MotdVassal, which was started by MotdOverLord.

• The user selected through a graphical display the parts that were to be tested and then selected run.
• The tool started up the needed processes by requesting them through Orbix.
• I also built the Data Input Manager, which started up one or more data input threads, where each thread would transfer data from an input file to a specific message queue.
• The average percent done of each thread was sent via IPC back to the parent tool process.
• Object Modeling Technique (OMT), C++, Rogue Wave and ILOG I designed and built a GUI that allowed users to test various parts of a large 24/7 distributed UNIX (SGI) system.

Sr. Software Engineer

Confidential, Littleton, Colorado

• Designed and implemented changes to a 24/7 near Real - Time (asynchronous event handling) client-server application which was written using C, TCP/IP and MOTIF and ran in an UNIX (OSF1) environment on a DEC Alpha.
• The server captured and filtered large data files in Real-Time using pre-defined filters.
• Some of this data was captured and then copied to the user s workstations where they could access the data through the user interface on the client side.
• In addition I built a GUI prototype on several Alphas Using C, MOTIF and RPC, which allowed the users to retrieve various files in small or large quantities from a remote tape server.
• After the prototype was working, I also supported the integration of our latest software, which incorporated the above prototype capabilities into our client-server application.

Software Engineer

Confidential

• Supported an on - line database product which was composed of about forty-five databases and which ran 24/7 on distributed VAX/VMS computers located in Boston.
• I developed tools written in C and DCL, which were used for transferring data from various vendor tapes to tapes or disk.
• In addition, I helped with the monthly, quarterly and yearly database updates.

Software Engineer

Confidential

• Initially I was involved with developing a user interface for a Mission Control prototype using C and Dialog on four Apollo workstations.
• Data was distributed as needed between each workstation using a token ring network and sockets.
• A discrete event simulation built by me was used to step this prototype through various events.
• Multiple screens were developed where each screen had specific functions such as database maintenance, graphical presentations and graphical analysis of events, event clock with clock controls and display of events.
• My second task was to modify and develop C code for a 3D graphical simulation on a Silicon Graphics (UNIX) workstation.
• One of the enhancements developed for this simulation was a new mode that allowed an Apollo workstation to send events and commands to it using TCP/IP sockets across an Ethernet.
• Setting up the discrete event clock in the Mission Control simulation as a server and setting up the 3D simulation as a client accomplished this.
• This allowed the event clock running on the Apollo to send clock updates and events to the 3D simulation on the Silicon Graphics.
• My next task was to bundle various tools together under an easy to use menu driven interface using PV - WAVE and C in an UNIX (SUN) environment.
• I worked with the users to solve various problems and asked for their suggestions on how the evolving tool could be made easier and more useful for them.
• The number of modules for this tool grew to about 250 so I developed a few C scripts to help me keep track of all these modules.

Software Engineer

• At first, I was involved with translating ATLAS programs to Pascal.
• These Pascal programs were then used in a demonstration of a High Mobility Automatic Tester.
• We also rewrote the ATLAS verb drivers and the general - purpose utilities.
• The ATLAS verb driver generated the intermediate interface language (CIIL), which is based on IEEE standards.
• Later I was worked within the database group on an R&D project using a VAX 8000 series cluster, where about 150 software engineers were developing and integrating ADA programs.
