David Janzen Cal Poly CS Prof, Corporate Trainer

Dr. David Janzen has been teaching students and professionals to program for over fifteen years (he must have started when he was 12!).  He is an Associate Professor of Computer Science at Cal Poly in San Luis Obispo, a consultant and trainer with Simex, and co-founder of Steadfast Innovation, LLC. 

David received his PhD in Computer Science from the University of Kansas (Rock Chalk Jayhawks!) and his BS in Math and Computer Science from Tabor College (go Bluejays!).  He worked for Sprint where he built calling card fraud detection systems in Lisp and C++ to catch crooks.  He taught at Bethel College, a small Christian liberal arts college in Kansas for seven years, and now he has been on the faculty at Cal Poly since 2006.  He loves working with college students, and he teaches primarily on the edges - first-year introductory courses, and final-year software engineering capstone and graduate SE courses. 

David has been teaching Android app development since early 2010.  He contributed the Android labs created with his very competent graduate student, James Reed, to Google Code University where they received over 300K pageviews in the first year.  He has published at least six apps in the Android Market. None of them are as successful as Angry Birds, but Papyrus, his Android note-taking app with Steadfast Innovation, LLC is well on its way.  Several of his students' apps have resulted in startup companies, and one, Punchd, was even acquired by Google.

David's most recent research project is a web-based automated tutor for teaching computer programming which he uses in some of his courses.   He has had some great collaborators so he only deserves a fraction of the credit.  His PhD research examined the effects of test-driven development on software quality.

David lives in beautiful Morro Bay, California with his amazing wife and kids.  He is one fortunate guy.
