I am an expat working overseas and have not filed for 8 years. I need to backfile all my taxes to catchup. Looking for advice on best way to proceed.

I recommend you start by contacting The Taxpayer Advocate Service (TAS).  TAS is an independent organization within the IRS that helps people resolve tax problems with the IR.  For more information, go to: https://taxpayeradvocate.irs.gov/about-tas
