About us

We provide small businesses and non-profit groups access to free and low-cost software solutions.

We do this by utilizing Open Source software, which is virtually free software.

“If Open Source is free, why should we hire Expert Data Systems?”

The answer is our business proposition:

Smaller organizations could significantly lower their IT cost by using Open Source Software (compare to commercial software).  However, quite often they lack the in-house expertise to implement and support it.

Working with Expert Data Systems solves this gap:  Partnering with us will make Open Source the most cost-effective solution for your organization.

There are thousands of Open Source solutions.  While many are great, there are applications that are not fully debugged, do not provide support, and were not updated in years.  This is where we come in.   We:

  • Evaluate top-quality projects and pick the best ones
  • Fine-tune and configure each application to meet the client’s needs
  • Provide training
  • Provide support
  • Perform backups and security monitoring
  • Offer professional services

Expert Data Systems was founded in 1995 by David Sosenko, a PMI certified Project Manager Professional, as a custom software development provider. Over the years, in addition to developing custom software, we have used Open Source software in order to reduce our clients’ IT cost. In 2019 we made the decision to focus on and to expand our Open Source Software practice.
