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.
