Work Interests
My job interests include (but are not limited to) delivering
internet/intranet applications. My primary
development platform has been Windows NT/2000 for the last 6
years. But I have had extensive (if not recent) Unix experience and
my most recent experience was developing on Windows and deploying on
Linux.
My primary focus for the last 18 months or so that I was employed
has been in various aspects of converting from an existing
IIS/ASP web application (using a COM based business
logic server) to a Java Servlet based web application
accessing a Java JNI based business logic server running as a
separate process.
I mainly worked on implementing a transport layer between the Web
Application and the business logic server. My first implementation
was using JMS as the transport layer, I subsequently replaced
the JMS with RMI while maintaining API compatibility.
The new transport layer was a "drop in" and required
minimal programming changes (mainly configuration settings).
My most recent work was in reimplementing existing functionality in
the new application that was available in the original
application (web pages). This involved applying XSLT
stylesheets to XML data returned by the business logic server.
I would prefer working in a "smaller" environment
(Say not more than 25 people). I enjoy the freedom and the chance
to have greater impact on projects.
Projects / Work Experience
- Rational Software - I became part of the
ClearQuest team when Rational Software acquired Pure Atria
Software.
- Servlet/XSLT web development -
I was primarily involved in reimplementing existing ASP
functionality using XSLT in an Apache/Tomcat
environment.
- Server Transport Layer -
I first implemented the server transport layer using JMS. This was
somewhat complex - It used JMS Topics for server location and
identification and JMS Queues for RPC styled server calls. I
eventually replaced the underlying transport with Java RMI
thus picking up speed and losing the requirement of running in an
Application Server.
- CORBA Server Project -
I worked on a CORBA C++ backend and middle tier federated server
infrastructure consisting of at least three interoperating
servers. These servers provided cross platform business service
interfaces to the ClearQuest database backend. Ultimately these
servers were to run on WinNT, Win9x, and various Unix platforms but
current development was on WinNT. Initial development used the
Visibroker ORB (BOA) but was later moved to Orbix 3.0.1 (BOA) and
eventually to Orbix 2000 before the project was cancelled.
- ClearQuest Web -
I took over as lead programmer for the Web implementation of
ClearQuest in December, '97 through December '98. ClearQuest Web was
implemented with IIS, ASP on the server side that renders fairly
basic HTML with some Java Applets and JavaScript on the client
side. The target browsers were Netscape Navigator (versions 3.04 and
above) and Internet Explorer (versions 3.02 and above). I accessed
the ClearQuest business logic using VBScript and the ClearQuest
Automation, and ADO Objects.
- ClearQuest Specific Projects
- DB Conversion Tool -
I wrote a conversion tool in VisualBasic and DAO to convert
ClearQuest DB schemas and meta schemas between MS Access and SQL
Server. This let us ship an initially populated database as a single
.MDB file and then, at installation time, run a relativly simple
program to initialize a SQL Server database, letting DAO handle the
complexities of converting data types and transfering BLOB data.
- Reporting - I wrote a reporting module to
generate reports from the defect tracking database. The reporting
module processed a report definition file and a query object
associated with the database to generate an intermediate RTF
file. The file was then rendered using MSWord, either as an external
program or as an Embedded Automation Server.
When it was determined that we needed a WEB reporting interface the
original reporting engine was replaced with Crystal Reports
reporting engine. I initially wrote the integration to Crystal
Reports 5.0, then converted to Crystal Reports 6.0 (which has an OLE
Automation interface). The report definitions are stored in the
defect tracker's internal database in BLOBs and temporarily stored
on disk to render or edit the report.
- ConfigurationManagement - I set up the
project CM environment twice (Just once wasn't good enough).
- The first CM environment was
done with RCS with the repository being served on a
Samba share. A collection of perl scripts were written to
check out/in individual files as well as scripts to check out the
entire repository to a local disk for development. This was then
moved to a Windows NT Share when the requirement to
build the product on unix was deprecated.
- The project was then
put under ClearCase using ClearCase 3.1 on Windows NT
as the Vob server. The major effort on this was to convert the
existing software base from RCS to ClearCase and make the cut-over
happen quickly when it happened.
- Pure Software -
when QualTrak was acquired by Pure Software, a team was formed to
implement DDTs on the Win32 platform - I was a member of that
team. My primary task was to explore different methodologies and
technologies that could be used by that implementation.
- OLE wrapper interface for ODBC classes - I wrote
an initial implementation of OLE Automation wrapper classes for
"proof of concept". These classes were never
implemented but demonstrated the minimal capabilities to export the
ODBC api as OLE Automation objects.
- ODBC database interface - I wrote Object Level wrapper
Classes for an ODBC based repository for a Win32 based
Defect Tracking System.
- Implemented VT100 emulator as an MFC Document/View
architecture window/control as part of investigation of minimal port
of Unix XDDTS to Win32.
- Initial investigation of cross platform ui for the DDTS Defect
Tracking System. Created a ui rendering engine to display dialogs
on both Win32 and Unix from user authorable schemas.
- QualTrak I was one of the original
employees at QualTrak and was the primary DDTs developer.
QualTrak DDTS - I wrote the original xddts
X11/Motif interface program for the DDTS system. This application
ran on SunOS4.x, Solaris2.x, Ultrix, HPUX8.x, HPUX9.x, AIX, and Dec Alpha
using the Motif1.1.4 and Motif1.2.x libraries.
- TestExpert - I wrote the admintool and
exectool portions of TestExpert. This version of TestExpert
was built on top of the TET test toolkit harness. Both of these
tools had an X11/Motif user interface. This product evolved into
Pure Test Expert when QualTrak was acquired by Pure Software.
