Personal details
Summary
Free-lance
consultant, with more than 18 years of experience in international
software industry for a variety of customers. Broad
experience in software engineering, including team
management, information analysis and system design
responsibilities. Extensive experience with many software
environments on various hardware platforms. Strong
communication and self-management skills; will survive in
complex and challenging environments.
Internationally orientated. Fluent in English, Spanish

Joined Sybase Engineering (February 2005)
As of February 2005, I have suspended my consulting activities and joined Sybase Inc. as an employee, working in
Irfan Khan's evangelism group (which is part of Sybase Engineering).
In this new role, I am committed to keep doing what I've done in the past
years: providing the Sybase community with technical information aimed at
practical relevance and usefulness, allowing you to make the most
of Sybase products. The main difference will be that I'll now be working
with the full support of Sybase, rather than on my own.
Incidentally, my employment at Sybase has no effect on the availability of
my Sybase books and web site (which you're currently visiting): these will continue as before.
My email address at Sybase is robv @ sybase.com. I look forward to meeting
Sybase users at Techwave and other events!

on ASE and Replication Server that are not readily available. He is
extremely active in various newsgroups with quick helpful support to our Sybase

conferences.
Rob is Dutch and lives in the Netherlands. He has over 15 years experience in the software industry.
He is ASE certified and just recently published

Information for Recruiters
Please note that I have suspended my consulting activities as of February 2005.
Also, please note the following:
- I am currenty not looking for permanent employment positions.
- I am not available as a Unix administrator, nor for maintaining Stratus applications, even though these individual words indeed appear on my CV (it's amazing how many recruiters only seem to be doing a web search for some specific keywords, and then ignore the context in which these words appear!).
- Please don't ask me for an updated copy of my CV/resume -- it's all here on this page; just scroll up...
- Probably the second most frequent question I get from recruiters is whether I know anyone who's suitable for a certain position. My answer: maybe I do, but I won't pass names of individuals to third parties -- I would have to ask those individuals' permission first, and this would all take too much time.
Sometimes I might forward a recruiter's email to DBAs who are looking for a new position or project, but this is purely on an informal basis -- no guarantees.
