Thanks for dropping by my portfolio page.  I am an engineer by training and work in the software industry.  I moved to the Portsmouth  area in 2011 after stints in Boston and Virginia.  My hobbies include traveling, hockey and researching investments.  


Douglas Jacobson

I graduated from the University of New Hampshire in 2006 with degrees in Mechanical Engineering.  My roles spanned from the private and public sectors including test engineering, design engineering and systems engineering.  My interest in programming and development started two and a half years ago where I started doing data analysis on subjects that interested me.  I progressed to building and deploying full web applications to the cloud.  

Everyone has heard the phrase , " I want to make an app".  Often our lives are filled with significant obligations which can make pursuing our idea challenging.   Building applications is time consuming and difficult ; it does not have to be impossible.  We can help.  

Quickly eliminate the big universe of what not to do, followup with a fluent, multidisciplinary attach on what remains, then act decisively when, and only when, the right circumstances appear.
