Senior Software Developer

2012 - 2014
Megabus Pty, Ltd.
  • Worked on broad incremental features that were manually applied across all modules.
  • Fixed a problem due to the structural design of the run-time architecture of how the application ran its modules. Modified (outside of rewriting a key part of the run-time library) almost 200 dialogs and all the places that create those dialogs.
  • Made dialogs asynchronous, which required all the creators of those dialogs to use callback methods. Wrapped the dialogs in several library classes. Created asynchronous versions of these classes and callback wrapper classes so that a minimal amount of identical new code needed to be added to the existing codebase.
  • Wrote extensive documentation about the problem, describing its cause and the solution. Included documentation of the new classes and developer guides for modifying existing code and creating new code using the new classes. I conducted a training session for the development team.

Senior Software Developer

2009 - 2010
Megabus Pty, Ltd.
  • Worked on a project to rewrite/redesign/migrate/convert a legacy system into a modern GUI, Marlin GTX. Rewrote Microsoft PDS Basic programs into C++ on C++ Builder 2009, and also rewrote Watcom C++ and C++ Builder 6 applications using Btrieve into C++ Builder 2009/2010. Changed the database implementation from a Btrieve file-based model to a more SQL-compliant one. Worked on object, class, and user interface design.
  • Refactored a set of 42 data integrity calculation applications into one base C++ class and 42 derived constructor classes, and one singleton factory class to create the different calculation objects for each calculation type. Refactored because originally each calculation application was a separate application, with little common source code, and half of them were written in Basic, and the rest used a discarded database API; therefore, no smart refactoring tools could be used.
  • Refactored a second set of 38 data update applications written in Basic into one base C++ class, five derived modifications, and one singleton factory class to create the different update objects based upon a table of parameters for each update type.
  • Maintained (bug-fixes and features) the user interface, data entry and display, and business rules.
  • Converted all the project files for the entire system from Builder 2009 to Builder 2010. Wrote a small Perl script to change all text that previously included hardcoded link names and paths in the almost 200 project files.

Senior Software Engineer

1992 - 2009
LibraryWorld, Inc.
  • Developed the LibraryWorld family cross-platform Windows/Macintosh applications. Supported Windows XP, OS 9, and OS X using a common database.
  • Based the proprietary database around the MARC record. Used proprietary indexes to provide adequate performance on the desktop systems of the early 1990s.
  • Designed and implemented a proprietary report script and report engine for the LibraryWorld product line using a then state-of-the-art dot-command syntax. Implemented the report engine to display reports on-screen, print them, or write them to a file—all from the same script.
  • Planned the project to be stable and reliable, and my code has remained unchanged through 4-5 UI design evolutions.
  • Worked on the original LibraryWorld web version. Removed the UI, building a family of CGIs around this code. The CGIs provided most of the functionality of the LibraryWorld programs through the internet. LibraryNet was released in 1998 as a product for IIS and Apache on OS X. In 1999 and 2000, I created the LibraryCom web service, which replaced LibraryNet. The current LibraryWorld 2 web service was developed by LibraryWorld based upon my earlier designs.
  • Added library catalog record lookup on a web service and publishing catalog records to the web service by adding an asynchronous Telnet client to the applications.

  • Managed translation of the language database and added automatic translation database maintenance and resource text translation to the build system.
  • Migrated the rest of the development team to the new version. Created installation and usage guides for the tools and source code changes. Directed and managed the transition of the development team to the new source code and new tools.
  • Began migration of the application data store from a proprietary flat-file system to a SQL database. Created a database schema representing the current data and planned enhancements. Developed a set of object templates to encapsulate the relational database and additional business logic. Developed a Visual Studio wizard to generate source code and store procedure scripts from the tables in the schema using those templates.
  • Converted the user manual in FrameMaker into a Microsoft help file.
  • Maintained (bug fixes and features) the user interface, data entry and display, and business rules.
  • Created and used a series of Visual Basic macros within Visual Studio to semi-automate the movement of text from the source code files into the resource files.

Software Engineer

2006 - 2007
IGT Systems
  • Worked on the Commission-based Program Play (CBPP) module in requirements analysis, functional and technical specifications, user interface design, database specifications, software design, and programming implementation.
  • Developed an initial prototype of the module for the CBPP feature and used that prototype as a requirements analysis tool to elicit a greater degree of detail from the client regarding their functional requirements. Based on this, I developed a second prototype. Spent four days at the client site leading discussions with the client stakeholders to help them understand and decide upon the operation of the new feature so that I could refine and complete its specification.
  • Specified the database schema for configuration and operational data. Designed and wrote the application code to create, configure, and manage the CBPP programs and to calculate the rewards and commissions and the SQL stored procedures and functions for using and manipulating the data. Designed and implemented the user interface for all of this. Implemented the business logic in stored procedures and triggers that interacted asynchronously with other distributed applications and services. Except for the stored procedures and triggers, all programming was on the client-side. Also provided deployment support for the system’s installation in Macau.
  • Worked on an interface between the Advantage system and an external third-party CRM system. The interface was used to synchronize data and report events between the Advantage system and the CRM system. The interface was implemented as multi-threaded asynchronous TCP/IP client and server Windows services. The services, threads, asynchronous client, and asynchronous server were all implemented using the .NET framework, and the interface to the Advantage database was implemented using classes based upon ATL templates.
  • Maintained (bug-fixes and features) the user interface, data entry and display, and business rules.
Technologies: Windows XP, Microsoft SQL Server, Microsoft Visual C++, Visual Studio, Visual Studio .NET, XML, T-SQL (Transact-SQL), SQL, C++, User Interface (UI), User Experience (UX), Jira, REST APIs, Agile Software Development, Object-oriented Programming (OOP)

SwiftUICombined (2020)

https://github.com/DavidSReich/SwiftUICombined
What is SwiftUICombined? It's SwiftUIReference meets Combine. SwiftUIReference is GiphyTags meets SwiftUI.

This is a SwiftUI reference app based upon GiphyTags and then updated with Combine. It is written in Swift 5 and Xcode Version 11.4.1 (11E503a)

SwiftUIReference (2020)

https://github.com/DavidSReich/SwiftUIReference
This is a SwiftUI reference app based upon GiphyTags.

It's GIPHYTags meets SwiftUI!!

GIPHYTags (2017)

https://github.com/DavidSReich/GIPHYTags
GIPHYTags was developed as an example of modern Swift coding and illustrates how to use many idioms and patterns of Swift and iOS development.

Older source code for my games is also available on my GitHub page.

Trxilt

Trxilt is a game derived from a pencil-and-paper game by Rick Nordal. It is a two-play game and can be played on a single device and through the Game Center.

Stellar Hedron

Stellar Hedron is based on a pencil-and-paper game. It's a two-player game and can be played on a single device, through the Game Center or against the AI. This app is written in Swift and uses the Cocoa Touch, UIKit, Core Graphics, and the GameKit. It can be played on an iPad or iPhone.

Selfie Test Drive

Selfie Test Drive was developed for Fob App, Inc. The app is for users to combine selfies and their own background with car photos. They can then save a picture of them in their new car in their own driveway. They can then share the results with their friends.

I created the app based upon designs and specification from fob. The application is focused on image manipulation and composting, using images from the device. The application uses the camera, image picker, and gesture recognizers; connects to AWS and Facebook cloud services; and shares images with Facebook, Instagram and other social networking sites and external apps. Technology used included the Cocoa Touch, UIKit, Core Data, Core Graphics, MessageUI, AWS, and Facebook frameworks and SDKs. The work covered the user interface, database design, and display.

Several versions were released after my version, but Fob has removed itself and the app from the App Store.

Stellar Cram

Stellar Cram is a misère version of Cram, which is an impartial version of Domineering. Stellar Cram is a two-player game and can be played on a single device, through the Game Center or against the AI. This app is written in Swift and uses the Foundation, UIKit, and the GameKit. It can be played on an iPad or iPhone.

Dots & Boxes

Stellar Dots & Boxes was developed in Objective-C. This is an expanded version of Dots & Boxes, which is a pencil-and-paper game called Pig or Pen-the-Pig or Boxes. Stellar Dots & Boxes has several unique features. It has triangular and hexagonal playing grids in addition to the usual square grid, and all three grids can be played in three different sizes. I've also implemented a "strings-and-coins" variant, which is also unique. There are also seven different color palettes which were designed to be distinct for people with impaired color vision. Stellar Dots & Boxes can be played by 2, 3, or 4 players or against the AI. It was conceived as a social game with players sitting together around an iPad (or iPhone). This app uses the Foundation and the UIKit. The iPad version was designed for the larger playing area and is not just a larger implementation of the iPhone version.
