Oracle, Java/J2EE Developer, SRA International, Inc.
--------------------------------------------------
Developed a series of PL/SQL stored procedures in Oracle
10g needed by the Department of Veterans Affairs (VA) in
order to more efficiently exchange data and administer
veteran's benefits in coordination with the Department
of Defense (DoD). Also developed a suite of Linux shell
scripts to execute the stored procedures in conjunction
with an SOA, Web Services J2EE application I designed and
developed utilizing JBoss, JDeveloper, Java Swing clients,
and Spring HTTP Invoker over SSL.
Next, I worked on the Person Services Identity Management
(PSIM) project. The goal of PSIM is to provide a Java,
J2EE technical solution that consolidates many of the VAs
identity management database systems into one identity
management service. The current system uses Hibernate to
interface with a backend Oracle 10g schema to enumerate and
consolidate the patient demographic and medical information.
My major contribution was in replacing inefficient, legacy
custom code with JMS and Message Driven Beans (MDBs) to
improve PSIM processing performance of the incoming and
outgoing HL7 messages that contain the demographic and
medical data to be stored and/or retrieved.
The application is developed and built using Eclipse and
Ant, deployed to WebLogic 8.1, and unit tested with JUnit.
Version control consisted of a hybrid CVS transitioning
to Rational ClearCase and ClearQuest.
04/2006 - 10/2007
Java/J2EE Developer, Unisys, Inc.
--------------------------------------------------
Designed and developed standalone Java and J2EE, EJB
applications in order to migrate various application
entities of the Automated Targeting System (ATS) over
to a Java environment. The system currently employed
by DHS, Customs, is built to handle about one million
messages a day using IBM WebSphere MQ Client 5.3. I
replaced some of the older "C" programs in the application
chain with J2EE apps that receive and process shipment
information messages entering the system using Message
Driven Beans. As messages are passed through the chain
of heterogeneous applications, a step-by-step risk assess-
ment is performed by accessing data stored in an Oracle
10g database using PL/SQL, JDBC and SQL. All relevant
cargo, manifest, and shipping information is accumulated
and have database-stored rules applied against them.
Risk levels are determined, and recommended actions, if
any, are formulated and passed on to the appropriate
application in the chain for further analysis and pro-
cessing. Interim as well as final risk evaluation results
are stored in the Oracle database for other interested
parties to examine.
As a result of this migration, more of the applications
in the chain are able to send and receive embedded Java
Objects to and from their respective MDB Queues. In
other situations, XmlBeans 2.2.0 is used to transform
these risk evaluation result Java Objects into XML for
chained applications that expect to receive their MQ
messages in XML format.
The web applications are deployed and run under JBoss
4.0.4. For the standalone Java utilities and sandbox
testing, I took advantage of other open source tech-
nologies such as Spring 2.0, Hibernate 3.2, and ActiveMQ
4.0. All the code was written and managed within the
Eclipse 3.2 IDE, built with Ant scripts, and version
controlled with CVS.
09/2005 - 02/2006
Java/J2EE Developer, Verizon, Inc.
--------------------------------------------------
Designed and developed JSP's and Servlets to operate
within the Struts Action Framework. My efforts were
concentrated mainly on Java/J2EE development, while
another team member focused his skills on stylesheets
and HTML presentation. Together, we implemented a
series of dashboard web applications designed for
internal Verizon use only. These dashboard applications
allowed the operator to fill out web-based forms,
submit their queries, and then review the resultant
output status and statistical reports generated by the
software.
I was responsible for implementing the Action Servlet
methods and JSP's that performed the database queries,
processed the returned data set, and then routed the
formatted data to the appropriate set of tiled JSP's
for browser display.
The web applications were run locally on Tomcat 4.0.6
for testing and then deployed to a Weblogic 7.0,
JVM 1.4.2 environment. Internal Verizon database
access was implemented using CEM middleware and Oracle.
Code versioning control was handled by CM Synergy 6.1,
and Eclipse 3.0 with Ant was used as the development IDE.
09/2003 - 07/2005
Java Developer, Urban Architectures, Inc.
--------------------------------------------------
The National Weather Service (NWS), Office of Hydrologic
Development, maintains a suite of programs that mathe-
matically computer model America's river systems. The
model input is based on historical data as well as real-
time uploads provided by USGS gaging stations and other
government agencies.
My project, the FLooD Analysis Tool (FLDAT), is a Java
Swing application I developed that has the ability to
import and consolidate input from these disparate data
sources, allowing the hydrologist to work with differing
types and formats of hydrologic data from within one
common GUI interface, in conjunction with MySQL, JDBC,
and Red Hat Linux. Other features I implemented using
the Java Swing components included an extensive set of
graphs, charts, and animation routines that showcased
river flow dynamics over time. I also developed a series
of interactve paint utilities designed to work on topo-
graphical images that allowed the user to draw and define
their own river channel characteristics. This graphical
data could then be translated, exported, and used as
modeling input. This relieved the hydrologist of having
to repetitively calibrate their modeling input parameters
by trial and error.
11/2000 - 08/2001
Java/J2EE Developer, Ecocys Technologies, Inc.
--------------------------------------------------
I was responsible for designing and developing Java
client/server software applications using JINI and J2EE
technologies in order to create a suite of distributed
Web Services for LAN, WAN, and wireless end users. Web
Services implemented included Automated WorkFlow Processing,
Document/File Sharing, and Instant Messaging.
JINI was used to implement the networked peer-to-peer
services, such as Instant Messaging. For web-based
applications, we used the Weblogic J2EE Web Application
Server, with an Oracle 8i RDBMS as the backend database.
Internet clients were delivered web pages using a variety
of HTML, JSP's, Applets and Servlets. Database data
was retrieved via JDBC in concert with EJB's, using
Stateless Session Bean facades that looked up various
BMP Entity Beans to perform the SQL.
12/1998 - 03/2000
Team Lead, BancTec, Inc.
--------------------------------------------------
I headed up a team of six people tasked for the Federal
Reserve Bank of St. Louis data archiving project.
Developing in Java, C, and C++, the project entailed the
ongoing capture and storage of terabytes of check data
processed daily by the FRBSTL. The data consisted of
check images in TIFF and JPEG format along with the MICR
data encoded on the check. This data would then be
indexed and stored on disk farms, tape jukeboxes, and
optical disks for long-term storage.
My duties as team lead included requirements analysis,
system and software design documentation, traveling to
and from St. Louis to consult with the client, assigning
software tasks and performing code reviews, and preparing
and implementing an array of QA test plans.
As a developer, I was responsible for writing Java, C
and C++ client/server applications for the HP Unix,
Digital Unix, and Windows NT platforms. These appli-
cations accumulated raw check data from various remote
locations and scheduled it for phased staging and database
storage using JDBC or Informix embedded ESQL/C. I also
designed and developed the Informix database tables,
schemas, and stored procedures that were used to process,
index, and store the data. Other duties included writing
a series of Unix shell scripts for cron to perform off-
hours batch processing of the accumulated check data.
01/1998 - 11/1998
Lead Developer, Commonwealth Scientific Corp.
--------------------------------------------------
CSC manufactures ion beam etching and deposition equipment.
I was tasked to rework all the Human Machine Interface (HMI)
software. This is embedded C code for PCM's (Programmable
Controller Modules) that interfaces with ladder logic, which
in turn monitors and controls the devices and sensors
operating on behalf of the ion beam machinery. Of special
note is a rewrite I did of the robot arm controller code.
The robot arm had had a nasty habit of picking up processed
wafers and then bashing them to bits against the wall of the
vacuum chamber. When a potential customer was satisfied that
this problem had been solved once and for all, they went ahead
and ordered 10 ion beam etching machines, a purchase that
generated revenues of over 10 million dollars for Commonwealth.
I also developed and maintained C++ GUI applications for OS/2
and Windows NT that were created using IBM's Visual Age C++
and Microsoft's Visual C++ and MFC. These client GUI appli-
cations were designed to enable the user to visually interact
with devices and sensors, providing real-time management and
control of the ion beam etching and deposition process as it
occurred. The user could issue commands to speed up, slow
down actuators, open and close gas valves, etc., all while
real-time feedback of the status of the ongoing processing
was being updated and reported back to the user via the GUI.
12/1996 - 11/1997
Contractor, GE Spacenet
--------------------------------------------------
At GE, I wrote TCP/IP, Berkeley socket C programs designed
to synchronize communications, data transfers, and message
routing among the customers of GE's SkyStar Advantage
satellite network. The client/server C applications were
written to run on both the Sun Sparc and OS/2 workstations.
10/1995 - 06/1996
Contractor, Coopers & Lybrand, LLC
--------------------------------------------------
A three-person team was assembled to develop financial
computer modeling applications. These financial modeling
programs were written in C for the OS/2 platform.
Synthesized IRS tax records, representing millions of
individual US tax returns, was used as a baseline. Then,
by varying other input parameters, such as expected rates
of inflation, FED interest rates, and proposed Congressional
tax cuts/hikes, the software would produce macro forecasts
and predictions concerning the US economy. This tool aided
Coopers & Lybrand in formulating their overall financial
strategy, both for themselves and their clients.
07/1994 - 04/1995
Contractor, MCI
--------------------------------------------------
Here I joined a team of 5 MCI developers where I assisted
in the object-oriented analysis, design and development
of a software system intended to monitor the operational
status of MCI's telephone network. Each node in the
network (telco switch station, mainframe) required a
node-dependent application running on it that was capable
of sending/receiving queries and/or data to and from other
heterogeneous application nodes along the route.
I was tasked to write C++ applications for OS/2 servers
to process queries, issue status and statistical reports,
and interface with other application nodes in order to
verify connectivity. I also helped to develop C++, OS/2
client GUI programs which provided the user with a visual
representation of the state of the network, as well as
the ability to interact with the system in real time.
For example, by pointing and clicking on a device icon,
a user could issue a command for the device to halt,
download new software, and then issue a command for the
device to restart itself.
08/1988 - 07/1994
Sr. Software Engineer, KEE Systems Inc.
--------------------------------------------------
At KEE Systems (now Sylvan Learning), I wrote CBT software
applications to provide customers computer based training,
tutoring, and testing facilities. For instance, using a
combination of screen capture and original programming,
I designed and developed a self-paced software simulation
of Microsoft's Word for Windows. Individuals and companies
would use this software to train themselves and/or their
staff to learn how to use the product.
One project where I was responsible for everything (client
interaction, design, development, QA and delivery) was a
Lotus-123 simulation and testing program. It was written
in C and assembly language, data and test results were
loaded from and stored to a database using Btrieve, and
was used by Lotus Corp. to verify the skill level of
potential hirees. It won an award for "Testing Software
of the Year" by an education magazine.
Almost all of the code was C code for DOS, and later Windows
3.0. In those days, I had to code my own mouse pointers,
keyboard and mouse interrupts, graphical bitblts, you name
it. At some point, IBM introduced OS/2 and requested KEE
to provide OS/2 versions of all of our training and tutoring
software products. I then ported all the DOS C code,
perhaps several hundred thousand lines of code, to the then
new OS/2 GUI operating system. This not only created a
whole new distibution channel for KEE and it's product line,
it also helped to establish a strategic and profitable busi-
ness relationship between KEE and IBM for years to come.
12/1986 - 03/1988
Contractor, 3M Vision Systems
--------------------------------------------------
I was part of a research and development team (4 people)
tasked to explore the feasibility of creating a new 3M
product to be called "Vision Phone". A television camera
was plugged into a digitizer board housed in a PC. The
current TV image could be displayed on your monitor, in
black and white, and then could be captured and saved to
your hard disk. The idea was that people could use this
product to take a snapshot of an architectural blueprint,
a family member, whatever, and then send the image over
a modem to another end-user who had also purchased the
same software and equipment.
All the code was written in C for the OS9 platform, and
involved intensive pixel manipulation. I wrote paint box
utilities to cut and paste sections of images, gray scale
correlating algorithms that sought to preserve and enhance
the resultant quality of the image when it was zoomed in,
zoomed out, rotated, etc.
12/1980 - 11/1986
Account Executive, Lynchval Systems Inc.
--------------------------------------------------
I wrote computer programs in FORTRAN (on punch cards) in
order to analyze and valuate pension plans based on actuarial
mathematics. Client companies would send me their raw
employee data containing the employee's age, sex, date of
hire and salary history. The FORTRAN program would then
iterate through the data to calculate individual as well
as aggregate future liabilities of the proposed pension
plan. By varying input parameters, such as expected rates
of salary increases and differing death and disability
probability tables, each iteration would perform a
statistical analysis of the data, giving clients a range
of pension plan options to choose from.
In 1983, we began migrating the system from a FORTRAN,
mainframe, punch card environment to a PC based system
ported to the C programming language.
