The Author

‚ÄčIT Security PKI Consultant (Retired)


This group of pages describes a little of my former professional self and evidences some of the work I undertook.  I've published a few items about an IT security capability in which I supposedly exhibited expertise - Public Key Infrastructure (PKI).  Following my retirement, I decided to keep it to look back upon rather than chuck it away.

My career
page displays certificates and awards I have gained, as well as newspaper and magazine articles written by or about me.  The page can be viewed by following this link, it's organised into the following three sections - I'm most excited about the latter :-)

  • Distant Past
  • Recent Past
  • Present and Future

Companies I Worked At or For
On a trip down nostalgia lane, I put together a list of most of the companies I worked at or for during my career, it can be viewed by following this 

During my career I gave presentations to audiences and delivered videos of technical solutions for use by customers, many of them can be viewed by following this

Perhaps the biggest single deliverable during my career was the authoring of documents.  I've published some PKI solution documentation, and also some legacy documents I wrote prior to specialising in PKI.  The documents can be accessed via this link.


During the covid pandemic of 2020 / 2021, I was unable to directly support people in my tech buddy role, so I devised approaches to help people manage their passwords.  I put together a "selfie-video" and a documented approach, both of which can be accessed via this link.

Public Key Infrastructure

I thought it a worthwhile exercise to publish the contents of a document I wrote for my then thirteen year old daughter, Olivia.  My goal had been to explain in a simple manner the professional work I was previously skilled at - see link.

IT Security Skills
Rather than publish a curriculum vitae / resume describing my IT security skills, this
link directs to a summary page of what I considered to be the highlights.
