My first contact with BPM systems was throw IBM Lotus Worflow a system on which I work for almost 4 years. In this time I develop new processes for telecom companies in Romania, mainly document management systems.

For a short period of time about half year a take part from a team that develop "from scratch" a BPM product that we called eDoc.net. The entire BPM engine was develop on .net technology all this time I learned the new technology and I was able to develop the module called "Organization". This system was a Lotus Workflow like system with the same functionality manners. This project gave me the big picture on how a BPM product worked.

Later on I was a technical leader on a project that took the eDoc.net product a put it on Java technology and became eDoc Java.

I have the chance to work with IBM BPM product too, not directly with it, I only do integration throw CMIS between IBM Filenet Content Manager. 

I get to know IBM BPM product well after I delivered a course of 10 days as a trainer on IBM BPM Advanced.

Now I'm working with Activiti an opensource BPM product I integrate it into a learning system based on Java technology.
