With over 20 years of programming experience, I have developed
applications for the small business and large corporation, from the small
utility (or library) to realtime financial trading systems. From in-house
application to commercial product.
|
My main development tool is Microsoft's Visual C++ (ver.
8.0 /
i.e. Visual Studio 2005),
but as a member of the Microsoft Developer Network I also have all
other Microsoft development tools, knowledge bases, operating systems and
development version of their primary business applications (including betas).
Using C++, I also concentrate on the following technologies: MFC, COM, XLL, DAO,
ADO and Grid based applications. (I have also worked on projects
using ASP.Net and C#.)
I use C++, not only because it produces the fastest executables,
but the language structure blends itself well with a windows environment, and
allows for flexibility, easier maintenance and future enhancements. And yes, it is more fun to use.

"C makes it easy to shoot yourself in
the foot. C++ makes it harder, but when you do, it blows away your whole
leg." - Bjarne

My first computer was a commodore VIC20. From 1984, working for
the local computer shop, I wrote
programs after school for local businesses. These were all in Basic, initially on CP/M machines and
then the first PCs. Later using dBase, and then Clipper (my first choice in a
language up until the days of Windows.)
On graduating, I went on to study 'Computer Data Processing' for
another 3 years, and during that time in 1988, I became self employed developing
applications in Clipper and C.
In mid 1989 I joined the headquarters of a large IT
multinational, where in addition to management reporting and consolidating their
financial results, I developed a
range of applications for internal use, for both the HQ and the local
subsidiaries.
I primarily used Clipper and C, but also RPG and Synon and later C++.
In 1995 I joined an international money and foreign exchange
broker, where I developed and maintained front office trading and back office
applications, using Visual C++, Powerbuilder, Excel, Access and Informix.
Since the beginning of 1998 I registered my own company, concentrating on C++
software development and providing my software products and services to
companies around the world on a telework basis.
I work on a telecommute basis from my house via the internet. I am always interested
in new projects, both long and short term. I am
interested in 'from scratch' development or maintaining, enhancing and
supporting applications on an ongoing and as-needed basis. Commercial ventures,
and optimizing / re-writing existing applications that are too slow.
If you are interested in my services, require further
information, or wish to discuss the possibilities of a project, please email me

I, since 1998, have been a telecommuter, or more appropriately
teleworker. Working from my home office, I have developed software,
maintained and supported my applications, and assisted my customers as
needed, including on other continents. |
It is a means of working which I enjoy as it offers flexibility,
diversity, freedom and a challenge. The users of my software, my clients and
myself all benefit with the flexibility and directness which fills the gap in standard employer/employee,
company/contractor and business/business relations.
As every customers needs are different, so too are the agreement
possibilities, with the most common being by group of 50 hours.
Teleworking is in its early days, but with the flexibility and
financial benefits that it offers both companies and the teleworker, I believe that it will become a much more common form of
partnership as time goes by.
Equipped with high speed internet access, a LAN, and the
latest hardware, software and development tools, I probably have all that is
needed to begin working with you.
If you feel that there may be a service that I may be able to
provide your company on a telework basis, please let me know on
leov@QMatix.com.
My name is Leo van Rijswijk. My mother tongue is English with my
day to day language now being French. I am 40 years old,
married, have a son and daughter and live in south-western France.
If you are reading this, after having read the other
sections of my web page, you have a pretty good idea what I do and have done.
During that time, job changes and relocations have led me to live
in London (England), Paris (France), Frankfurt (Germany), Luxembourg, Johannesburg (South Africa) and Lugano (Switzerland).
Due to job requirements I had the privilege of traveling on a
number of occasions to the USA, to most European countries, around Asia
and Australia and to Canada.
I have since, with advances in the internet, established my
office from the home, where I now develop software and support my customers
around the world.
