Resume Wim Nederend

Profession: Programmer, Software Architect, Software Engineer or whatever fancy names they come up with for people who can be responsible for making good computer software.

I'm married, I have 3 children, they were born in 1992 and 1993.

I'm good at doing all what's to be done at the software creation process: from rough sketching on a whiteboard, together with other programmers, through documentation writing, coding and debugging.

Sometimes I compare it with building your own house, from digging the trenches for the foundation and pushing wheelbarrows with concrete, through implementing the electrical installation, up to the architectural design.

In "My opinions about how companies should be managed" I wrote a few lines, not to be part of a resume.

Education

1990-1998: Some postdoc courses:

1993: Spatial data structures
1998: Design patterns and Software architecture

1979-1987: Graduation Technical University of Delft

Department of Electrical Engineering.
Thesis work: design and realization of an operating environment for a PC board, for a speech processing application. The board contained 2 computers, an Intel 286 based one and a Texas Instruments 32010 signal processor based one. It's this time my interest in real time operating systems grew.

1973-1979: VWO, St Antoniuscollege, Gouda

The first 4 years in Delft I was member of a race rowing team. After this I coached a team for 2 years. In 1983 I was chairman of the club's introduction committee.

Work

1988-now: AND

2001-now(spring 2002): AND Products B.V.

Spring 2001 AND International Publishers N.V. went into voluntary receivership (Dutch: surseance van betaling). A Dutch investor (Roosland Beheer) showed confidence in our most important activities. May 2001, we continued the Dutch operation with a 20 persons, a reduction of almost 90%. We managed to keep the listing at the Euronext stock exchange, Amsterdam.

All people in the Rotterdam office was involved at determinining the strategy of the business. There will be a strong focus on the 'Location Based Services', route planning and address verification. We want to have a piece of the cake in the transition from 'car navigation systems' into 'mobile navigation systems', and hope (expect!) that it will be as revolutionary as the transition from 'car telephony' into 'mobile telephony'.

Though I did some work on maintenance on current AND products last summer, I continued development on the new generation of routeplanners. A patent on some techniques used is pending.

I learnt a lot in the year 2001, probably it is clear to the reader that looking for a new job is not very actual.....

2000-now: Ucp route planner

Autumn 1999 was decided to develop a new generation of route planners. The route planning library, makes use of a backbone road network, connected to street networks through socalled UCP's (universal connection points).
In this context a backbone network is a selection of the most important roads. A street network is a road network consisting of all paved roads ever made in a certain area.

I am responsible for the design and realisation of the data access layers, and for the design and realisation of the tools for assigning the Ucp's in the data files.

Despite the high seas my employing company is sailing in, current project is the most interesting (so most enjoyable) I have ever been involved with:

• My child, the MapDat library classes, are used both at data capture, data preparation for the planning engines, as the planning engines themselves.
• I'm working in a team of people of a variety of skills (some residing abroad, in Ireland), I can learn a lot from them (UML based design, new C++ and STL features) as well as I can learn other people a lot (nice neat programming).
• It may be one of the lifelines, to save the company

1999-now: AND Data Solutions B.V.

In 1999 AND Mappings activities were transferred to Ireland. The development teams of all (now called Data Solutions) activities were joined. I became member of the libraries and tools development team. My focus stayed on the development of MapDat based tools.

1994-1999: AND Mapping B.V.

The summer of 1994 I was asked to work exclusively for AND's data capturing subsidiary. I was responsible for all development, and the coordination of the operations (from coordinating the data capturing team leaders to the design of the IT infrastructure together with the sytem administrator). When the company grew, my focus became more to the development.

At joining Mapping, it was already clear current tools set's life cycle was ending. (though its still used in 2001!) The old tool set was developed by me in the quiet hours in my early years at AND.
So the development of the MapDat library started. It's based on a quad tree spatial datastructure. The data stored have an object oriented data model.
The MapDat library forms the file access layer of the Ucp road planning library.
Though already some customer projects were fulfilled with it in 1997, due other priorities the tool set based on it still is not widely in use at our data capturing offices (the old stuff works well enough.....)

1992: Conversion of ARTOL data.

The city of Rotterdam maintains a large geographical database at a scale of 1:1000. In 1992 they switched to a new GIS to maintain it. I made some tools to convert the data for the new system. Operations were generalization, fitting small holes in line data of the same class and converting curves into strings of circle arcs.

1990-1992: Waterdepth management system

In 1990 development of the Waterdepth Management System (WMS) was started. I was detached from AND, through Rotterdam's Public Works, at the Rotterdam Port Authority. I was responsible for the design and realisation, based of a defintion study done by people of Public Works and the Port Authority.

The WMS is a system used at the traffic control center of the Port of Rotterdam. It evaluates the access of ships to the port with respect to the depth of the water, before the ship is entering the port. Used are depth measurements (millions of samples) of the water and a tide level forecast. The user interface is a graphical display, showing the predicted track of the ship. Part of the system is a module which automatically fetches the depth measurements from the level measurement stations. It is implemented on Sun Sparc systems. Almost all design and realization I did myself.

The system still has a place on the console of the traffic leaders of the port of Rotterdam. Although it doesn't have the central place as aimed in the design phase, it is still useful a an electronic depth map. (which is not bad for a ten year old software system). I'm around at the customer's site for a week once a year to do some maintenance.

1988-1991: detachment at Rotterdam Public Works

In July 1988 I started working at AND Software B.V. The first years I was almost full-time working at Public Works of Rotterdam. Mostly maintenance of FORTRAN based information systems. Later C.

Next to my detachment activities I designed and realized the tools for maintaining the AND road network database. The main tool is a network editor which is capable to operate on the entire database (up to a few millions of nodes) at once. Other tools concerning the database do plotting, checks on connectivity and various errors and generalization. These tools are still used at AND's production facilities in India and Ireland

1985-1988: TDD computer engineering.

During the last years at the university I started together with 3 other persons a little company. The year after graduation I worked full-time for it. We were developing dedicated microprocessor based systems, both hardware and software. Most successful product was a compiler package for the 6809 microprocessor.

Hobbies

I'm one of the lucky people who made a profession from his hobby. At home I have a little network of Linux and Solaris machines.

I like to work at my house (painting and alike) and the garden. (the analogy referred in the beginning of this text is'nt so so strange to me).

From time to time I do some private transactions at the stock market.

I still manage to run for an hour every sunday morning. Now the children have the age for it we don't want to miss the spring ski holidays anymore.
