I'm doing some SSIS upgrade and PCI compliance work for a retail client.  As I connected to one of their database servers there was a database named TrustedLink.  That rang a bell and when I asked they told me it was "for their EDI program, did I know anything about it?"  In fact I did, I had helped write it.

Not long before I'd been interviewing at a company and they asked me about web service interfaces.  I mentioned to them I'd done a tool called Reflection that brings a copy of a Salesforce.com database in-house to facilitate integration with other systems.  They said "Oh, that's cool.  We use that."

I've had similar experiences in the past with True Automation's county appraisal and tax collection software and IBM's old ImagePlus document imaging.  I had a big part in True Automation's architecture and database design (now in the very capable hands of Jon Coco) and was a Windows consultant at IBM's Toronto lab for ImagePlus.

All of these were past projects that popped back into my life after the fact.  A lot of my work over the yeas has been systems integration and BI projects that lived their lives behind a client's doors so I'd only see it if when I did new work for them.  But it's somehow gratifying to see glimpses of things I've devoted big chunks of my life to.  I guess it's the software equivalent of grandkids.
