> > working with open source, coding style, licensing
> > decisions, testing, building, packaging and release.

> > Mike Pittaro started the SnapLogic project in 2005
> > with the goal of simplifying data integration with a
> > fundamentally new approach.

> > Mike has worked in the data analysis and data integration
> > space for the past 12 years. He built his first financial
> > data mart in 1996, and later worked on pool selection
> > analysis for the asset-backed securitization industry.
> > Mike joined Informatica in 1997, where he worked on product
> > advocacy and developed the support infrastructure for the
> > Global Support Organization which used a mixture of
> > commercial and Open Source software to enable collaboration
> > and resource sharing across five distributed support centers.
> > Prior to that he worked in the high performance computer
> > industry, optimizing Fortran and C programs for massively
> > parallel computers. Mike graduated from the Sligo Institute
> > of Technology in 1983.
