I am a software engineer. For 20 years I have helped my clients design, develop and release software in the defense, health and financial industries. I enjoy teaching, mentoring and public speaking. I have several open source projects on GitHub.

I currently spend my days developing for iOS (Swift/ ObjC).


 

Current

I am a Principal Software Engineer for National Information Solutions Cooperative. I lead a small team of iOS and Android developers.


 

High Rail App

I am the developer behind High Rail, an iOS app for controlling Lionel “toy train” engines, Lionel LCS SensorTracks, and other Lionel hardware. High Rail is available on the App Store.

High Rail started off in ObjC (because Swift did not yet exist). I re-wrote the entire code base in Swift 2, mostly as a learning exercise. Then came Swift 3, so I effectively re-wrote the app again. The latest version is Swift 4.


 

Coolest App I Got Paid To Develop

  • an aero-mechanical data analysis framework for graphing and analyzing flight test data

 

I Enjoy Public Speaking

  • CocoaConf Speaker
    • Core Animation
    • Concurrency and Architecture
    • Unit Testing
  • For years I led the St. Louis CocoaHeads group, and spoke often on various software engineering topics.
  • I created and delivered numerous software programming courses for Washington University’s CAIT program (through a previous employer Object Computing, Inc.)
