Welcome to my Web Portfolio! I am David Glatzl, software engineer. In 2012 I graduated with highest distinction from the College of Westchester located in White Plains, NY with an overall [3.9] GPA, Summa Cum Laude, obtaining an AAS (Associate in Applied Science) Degree.
My major was in Digital Media. It was a well-rounded curriculum that taught Web Design and Development which is one of my passions. My experience as a software engineer for Simply Sacred Oils for the past ten years has given me the opportunity to really make a significant contribution to growing this entrepreneur’s businesses.
This section contains JavaScript, PHP and C++ code samples written by me, website author David Glatzl. The purpose of this code sample portfolio is to demonstrate my knowledge and skill of these programming languages.
