Big Nerd Ranch, iOS Essentials with Swift, Computer Software Engineering




A life-long learner and technology enthusiast, I have been working with computers since 1983. My programming experiences began by operating and maintaining a small, text-based Bulletin Board System (BBS) on a 300 baud modem using an Apple IIc computer as a (woefully inadequate) server in the early 80s. My fascination with technology and computers carries on, thanks to an insatiable desire to learn, understand, and usefully employ the latest technological innovations. Specialties: Microsoft’s Visual Studio on both Mac and Windows, with a recent focus since 2016 on mobile development for Android and iOS using Xamarin.Forms. Previously, I specialized in desktop and web development with C#.


  • Full Stack Developer

    Hunter Industries

    December 2017 – Present(1 year 10 months)San Marcos, CA

    Working with a small team of developers practicing software craftsmanship through “mob programming” (allowing for constant peer review and on-demand design/architecture discussions), Test Driven Development (TDD), and a drive for implementing best-practices in pursuit of delivering software of the highest quality. My team successfully went to production with a mobile app for Android and iOS devices using Xamarin Forms, bringing our experiment in cross-platform mobile development to fruition. This experiment allowed us to build two apps for little more than the price of one, and allowed users to benefit from our software regardless of their preferred platform.

  • Lecturer

    California State University San Marcos

    January 2018 – May 2018(4 months)San Marcos, CA

    Developed, refined, and taught curriculum at CSU San Marcos to teach cross-platform mobile development for the iOS and Android platforms with Xamarin.Forms for an upper-division elective (CS 481). Students with little to no mobile experience learned to create apps which typically had 100% shared code across platforms. A sample lesson on tabbed navigation can be found on Bitbucket at, and a variety of tutorials is available at

  • Senior Software Developer

    Hunter Industries

    December 2016 – December 2017(1 year)San Marcos, CA

    After conducting research and a proof-of-concept mobile app in 2016, embarked on a journey building a cross-platform, native (non-hybrid) mobile app that could be deployed to both iOS and Android platforms without requiring separate teams, codebases, etc. Using Xamarin.Forms, the vast majority of our code is shared across platforms, with a few exceptions where some platform-specific coding has been required. This was the first in-house mobile app the software development team took on. I hope to help grow and improve Hunter’s budding mobile app presence by helping develop mobile apps that are performant, reliable, and fun to use.

  • Software Developer

    Hunter Industries

    December 2015 – December 2016(1 year)San Marcos, CA

    Worked in a team of 20+ software developers who are split up into smaller groups called “mobs” (see for more information on mob programming). Helped to promote and constantly improve this exceptional environment for producing the highest possible quality software for both internal and external-facing solutions while simultaneously boosting the whole team’s knowledge of the software itself and development best practices. All code is written using a TDD (Test Driven Development) approach, including unit tests and full-integration UI tests. Using specifications written in Gherkin syntax, we are able to create a living set of documentation executable as tests to ensure new code does not introduce bugs to existing functionality.

  • Software Developer

    Human Longevity, Inc.

    January 2015 – November 2015(10 months)San Diego, CA

    Working on software that orchestrates the handling and processing of genetic sequencing data for a bleeding-edge biotech company with goals of extending life and improving treatments by studying the subject’s genome. Personally responsible for enhancing and maintaining a WPF application monitoring the output from genetic sequencers and for various services constituting a workflow to process large amounts of genetic data. Gained valuable experience with Amazon Web Services including S3, EC2, Cloud Formation and to a lesser degree SNS, SQS and Lambda functions.

  • Software Developer

    Bridgepoint Education

    December 2012 – December 2014(2 years)Greater San Diego Area

    Proud member of a fantastic software development team working on Bridgepoint’s online assessment software for the education field, Waypoint Outcomes. The project core is an ASP.NET MVC app with a SQL Server back end. Waypoint also has given me the opportunity to get back into some Java development for integration with third party software as well as gain experience with NHibernate, Unity Application Block, MOQ, JavaScript, JQuery, AngularJS and more.

  • Software Engineer 2

    Mitchell International

    October 2010 – November 2012(2 years 1 month)San Diego, CA

    Cutting edge software development using .NET 4.0, C#, WPF, Entity Framework (SQL Server 2008 r2 Express back end), PostSharp AOP framework, MVVM design pattern employing the Prism framework and Unity dependency injection container for modular development of loosely coupled concerns that is exceptionally testable.

  • Software Developer

    Independent Consultant

    January 2008 – October 2010(2 years 9 months)

    Developed a few small applications and websites, but the vast majority of this part of my career was spent building a complete “costing” desktop application for an athletic wear company to assist in their tracking of negotiations with factories around the world to manufacture the clothing items they design. The requirements called for an application that would run on both Mac and Windows systems, so I chose to use the REALbasic programming language and IDE (recently rebranded as Xojo), and a Microsoft SQL Server back end. For the entire application, there is only one single line of code differing for the Mac vs. Windows version. This costing system was my first foray into true object oriented software development on an even remotely large scale, and I am very happy to say that there have been almost no bugs, and the software has been in use by employees around the world since 2009. This project was an incredible challenge, and its success has been a source of pride and inspiration ever since. I am always excited when this client calls for a new feature, and gladly develop it for them in my spare time outside of my usual day job.

I also developed new AppleScripts to automate various processes such as connecting to server shares, batch-converting image formats, and most importantly archiving email attachments to reduce issues associated with large email databases, as well as reducing strain on the backup server.
