This is the second time I have been employed at PTO Exchange. PTO Exchange is a funded startup which helps employers and employees manage their unused PTO. The product is a SaaS application hosted on AWS. Technologies used include Windows, Linux, C#, .NET (formerly .NET Core), MVC, Razor, PostgreSQL, Python, POI, TypeScript, Docker, Terraform, Bootstrap, Material Design, Github Actions (for CI/CD), Redis, git/github, just about every AWS service it seems, Microsoft MAUI, and of course HTML, CSS, and related technologies. The site is SOC 2 compliant and regularly penetration tested by outside consultants. The platform has hundreds of thousands of users and is designed for efficiency, high loads, and follows all the security best practices. Being a small team all engineers help with testing, UI specification, and DevOps. We used Agile development principles implemented with both Kanban and Scrum methodologies. Additionally, our product implements a service-oriented architecture and a public REST API for our mobile clients.

As part of the Guild Wars 2 engineering team, I worked with artists, game designers, sound engineers, game play engineers, game engine engineers, build engineers, IT personnel, and other tools engineers to create new tools and maintain existing ones. This involved debugging and enhancing existing tools and workflows as well as creating new processes. I also maintained obsolete and unsupported 3rd party libraries and applications that were still integral to building and deploying the game. Some of the technologies used in this role were C/C++, C#, .NET Framework, WPF, HTML, TypeScript, and Perforce. This position was entirely remote, as the office had been shut down for the COVID pandemic. In addition to technical skills, this position required working with a hugely diverse set of very talented people with varying skills and backgrounds. I spent most of my time gathering and understanding the needs, requirements, limitations, and schedules of various teams. I contributed across the entire organization as needs arose, often involving putting out fires on short time frames. During my time with ArenaNet we released the End of Dragons expansion and began work on Secrets of the Obscure.

This is the first time I was employed at PTO Exchange. PTO Exchange is a funded startup which helps employers and employees manage their unused PTO. The product is a SaaS application hosted on Amazon Web Services. Technologies used include Linux, C#, .NET Core, MVC, Razor, PostgreSQL, Python, TypeScript, Docker, Terraform, Bootstrap, git and of course HTML and CSS. The site is SOC 2 compliant and regularly pen tested by outside auditors and consultants. For more details, see more recent experience with PTO Exchange at the top my profile.

Developed web-based applications for assessment and development of mathematical abilities in elementary school students. Technologies used include Linux, Apache, Perl, HTML::Mason, PostgreSQL, JQuery, JavaScript, Subversion (svn), Mercurial, Git and of course CSS and HTML.

Developed and managed a web-based application used in clinical trials for the treatment of Osteoarthritis of the Knee. The application is hosed on Amazon Web Services on Linux and Apache. Some technologies used include Perl, HTML::Mason, .NET Core, PostgreSQL, Subversion (svn), Mercurial, Git and all the standards of JavaScript, CSS and HTML.

I worked for this company twice over many years. I've included the same description in both listings. VHI produced software for the physical therapy market and was once the market leader in patient education software. The list of products I developed is very long, but our primary product was a Win32 desktop application written in C++. This was a monolithic application comprised of several hundred thousand lines of code. It started as a Win16 application using a custom developed b-tree database and evolved to a Win32, COM based application using Microsoft SQL server, SQLite and web-based technologies. There wasn't a technology that we didn't use in our desktop and web based products from Microsoft SQL Server, PostgreSQL, Perl, HTML::Mason, .NET, C#, MFC, Linux, Windows, HTML, CSS, JQuery, InstallShield, Apache, IIS, ISAPI, Mecurial, Git, CGI, SourceSafe and almost anything else you can mention over the years. Notable products were VHI PC-Kits which at one point was in daily use by 44,000 therapists in 3 countries, HelpMyKnees.com which was an online treatment program for musculoskeletal issues, VHILive which was an online exercise animation delivery platform, VHI Functional Assessment which was a desktop application of administrating functional testing such as Berg Balance, etc. We performed many clinical trials of our products under funding from the DOD, PCORI, VA, SBIR and NIH. While there I also worked closely with artists and animators to produce render pipelines and workflow tools to make their jobs easier and manage the creation of 12,000 animated exercises, in male and female and four ethnicities. This process used 3ds Max, FFmpeg, ImageMagick, Mental Ray, Scanline, Motion Analysis motion capture, EvaRT, Cortex, Backburner, CleanerXL.

This company was originally founded by one of the owners of Visual Health Information and a colleague of his. Therefore, I did work for both at the same time. They are now separate companies but I continued to do work for both. DMTI produces scientifically validated, web-based, K-2 mathematics assessment and instructional tools. I developed web-based applications for assessment and development of mathematical abilities in elementary school students. Technologies used include Linux, Apache, Perl, HTML::Mason, PostgreSQL, JQuery, JavaScript, Subversion (svn), Git and of course CSS and HTML. While here, I also implemented and managed government research grants through the SBIR program.

This was a startup which tracked and optimized web based advertising. Technologies used included C++, .NET, VisualBasic, Microsoft SQL Server and of course CSS and HTML.

This was a short contract development position on the Windows Management Instrumentation (WMI) product at Microsoft. Technologies used included C++, COM and Microsoft Visual SourceSafe.

Was part of the development team for Wall Data's Salsa database product which used the Semantic Object Model for database design and migration. Development was done in C++, MFC and Win32. My primary focus was UI development.

Taught a Winter Term course on Win32 development in C++ and MFC. The course had about 20 students and was a full credit computer science course. This was done concurrently as a sabbatical during my Wall Data employment.

Provided phone and online support for software development using the Windows SDK. Wrote code samples and Knowledge Base articles for Windows, MS-DOS and Windows SDK. Performed the SDK training for newly opened remote support facilities. Worked later as a Software Design Engineer in MAPI testing.

Wrote software tools to aid in their Statistical Process Control initiatives. These tools analyzed production test data with the goal of increasing wafer yields for their high speed gate array and SRAM products. This position used VMS, Pascal, C++, DCL, and SAS analytics software.
