This is a list of my project activities in
reverse-chronological order. I'm not including individual
seminars and workshops that I deliver almost every month
(unless it's a first seminar about a new, noteworthy
topic).

the projects themselves, see my Projects page.

| Solaris 10 Migration |
|
I am helping a bank in Luxemburg to migrate their IT
infrastructure to the Solaris 10 operating system.
In the course of this, many services and components
are upgraded to new product versions, such as
WebSphere Application Server 6.1. I am responsible
for scripting WebSphere installation, configuration,
and deployment, and also for the use of Solaris
Role-Based Access Control (RBAC) for various
security-related issues.

test framework of JacORB. Many more test cases were
added, to increase the test coverage in some
critical packages to over 80%.

| Transactions in JacORB |
|
For a company that uses JacORB in a critical
client/server application, I investigated scenarios
to integrate their application with XA-based
distributed transactions. Various prototypes were
produced.

encryption of sensitive data, as well as access
control and monitoring of critical systems.

| Java/CORBA Consulting |
|
A programming group in a pharmaceutical company in
the U.S. asked me to give them assistance for
maintaining a CORBA-based service. I was invited to
give a seminar on general CORBA technology, and to
have a closer look at the system in question. I was
able to suggest some improvements, and implemented
several changes in JacORB to help this particular
customer.

From the Reference
The consultant's knowledge of the product was first
hand. [...] He played a big part in the current
stability of our software. He was also very willing to
answer questions after he returned to Germany from the
U.S., as well as after he was paid for his
services. The consultant is one of those rare computer
scientists that excels because he invests time to truly
understand the things he passes. This includes but is
not limited to, tools, methodology and what I like to
call Computer Science philosophy. |

| Eclipse Training |
|
Delivered a three-day workshop on Eclipse
Plugin-development for a major IT company.
The course was held in one of the customer's
development labs in Ireland.

| Transition of a core banking system
to UNIX |
|
A bank in Luxemburg is migrating their core banking
system from VAX/VMS to Unix. My task was to
hold a number of seminars to introduce the
developers and administrators to the Unix operating
system (Solaris), to define coding conventions for
shell programming (ksh), to set up an infrastructure
for configuration management (CVS), and to migrate
existing batch processing scripts to Unix.

| 2003/07 – |
| h3270, a web-to-host adapter |
|
Many customers need to integrate legacy mainframe
applications with more recent, web-based systems.
For a partner company in Berlin, I develop and
maintain h3270, a web-to-host adapter that can be
integrated into portal servers.

| Position in Project: |

|
| 2003/04 – 2003/06 |
| Implementation of the Extensible
Transport Framework in JacORB |
|
The Extensible Transport Framework (ETF) is a new
CORBA standard that allows ORBs to use other
transport protocols besides TCP/IP. For an
industrial partner, I refactored the transport
layer in JacORB to support this new standard. At
the time of the implementation, ETF was still a
draft standard, and we provided feedback to the OMG
that helped in the finalization process.

| 2003/01 – 2003/02 |
| Portal Server Consulting |
|
A telecommunications company evaluated portal
technology to integrate some of their existing
information systems. We were able to point them to
Jakarta/Jetspeed, as an alternative to the
proprietary system they were evaluating. Not only
did this save them a lot of license costs, they
also chose the technology that was soon to become
the reference implementation for the new Portlet
API standard. A prototype that showed the
integration of some of their existing systems was
developed.

| 2002/09 – 2003/04 |
| Implementation of Asynchronous
Method Invocation in JacORB |
|
Sponsored by an industrial partner, I implemented
Asynchronous Method Invocation (AMI) in JacORB,
plus Quality of Service (QoS) policies for timing
individual requests. These are recent additions to
the CORBA standard, and JacORB was actually the
first Java ORB to have an implementation for them.
In the course of this project, I also extended the
JUnit regression test framework for JacORB, so that
it became possible to run end-to-end client/server
tests.
|
| Position in Project: |
Core Developer |
| Technologies Used: |
Java, CORBA, JUnit, Eclipse |
|
Reference The consultant did a great job
with adding AMI and connection management to
JacORB for us. The quality of the work was high
and he was a pleasure to work with. His knowledge
of JacORB and integrity helped to keep the concern
for the project to a minimum. We will definitely
work with the consultant again in future projects.

| Backport of JacORB to J2ME |
|
For a customer in the logistics business, JacORB
was backported to JDK 1.1 to make it usable with
J2ME.

| Position in Project: |

| Technologies Used: |

|
| 2001/12 – 2002/04 |
| Web Application Development, Banking |
|
For a bank in Berlin, a browser-based front-end to
a database for credit risk management was created.
Since this was the first use of Java technology in
this particular bank, our consulting team created a
number of generic frameworks that allowed rapid
application development, following the bank's user
interface styleguide.

| Implementation of Objects-by-Value
in JacORB |
|
Objects-by-Value (valuetypes, OBV) is the CORBA
equivalent to object serialization in Java. It is a
fairly recent addition to the CORBA standard.
Sponsored by the Free University of Berlin, I
implemented the OBV subsystem in JacORB, the free
Java ORB.

This is my PhD project, also known under the
name Pangaea. Since it involves source code
analysis, I developed a very thorough understanding
of the Java programming language during this project.
