● Designed and implemented improvements on various CI pipelines in ADO/AWS resulting in less work for developers and better results for all builds with easier to find artifacts and targets.● Delivery work on Mezzo, a kubernetes-based "common viewer" system for x-rays and other security scans. Built support and deployment tools to make it possible to actually field the system. Most tooling and work was for air-gapped environments and intended to be used by “tech-adjacent” workers. Worked with AWS CLI, terraform, zarf, helm, kubectl, bash, perl, .NET, WSL, Ubuntu, Rocky for k3s and rke2 clusters.● Development on RPM, a passive radiation monitoring vehicle portal for detecting illegal import/export of nuclear materials. Work included mostly C++ and C# porting and development, with some CI work to run certain builds faster and test more reliably.● Handled relevant technical end of L3-Harris merger, migrating years of developer content: Jira, Confluence, Bitbucket, and Gitlabs to ADO (boards/wiki/git/CI).● Second pass on all CI pipelines to automatically generate and push containers with reasonable default launch parameters for all eligible projects (Marked Dockerfiles and C# projects).

For Server Team, worked on Systems Manager, a hospital-facing, web-based medical device management system.Led C# effort and set guidelines for controller and model development on ASP.NET MVC portion of Systems Manager.Requirements gathering and MVC development for new features, such as managing device software and firmware by groups.Ported existing features from Webforms to MVC.For Embedded Team, worked on C# platform support for safety critical medical device running .NET Compact Framework 3.5.Wrote network code for device at multiple levels of network stack, including high-level messaging system used by other components such as the UI to easily send messages to other hardware.Wrote execution dispatchers for pub-sub message loop threads and various small but important features missing from Microsoft’s 3.5 framework.Drove and architected system-level Configuration Management system, and designed and wrote bedside device portion. The Configuration Management system was a powerful system which allowed the vast majority of the update process—update of firmware on multiple chips, clinical config, software, OS, etc—to happen while the device was clinically active, such as during an infusion.

Rapid application development in WPF/Silverlight for various companies. As a contrast to other work, I was extremely focused on the front-end, with heavy use of both Blend and hand-written XAML.Created custom controls, such as carousels, datepickers and comboboxes, where existing framework or third party controls did not exist or were not sufficiently extensible.Extensive of skinning of all controls, including custom controls, Microsoft controls, and Infragistics and Telerik controls in both WPF and Silverlight. Worked closely with graphic designers and UX professionals to ensure a polished look and feel to applications.All projects made use of RIA-style MVVM with various back-ends and ORMs.

Wrote small C# open-source API for Microsoft allowing service installers to register their services for trigger-start functionality. Made heavy use of C#/C++ interop. Did extensive work with Intel providing software under Windows, Linux, and OS X for graphics-related hardware (. Part of a team developing low-level hardware simulation in C++ with matching procedural API for the hardware in C++. Sole developer for OO C++ API, C# API and the OS X port of the entire suite from Linux. Most software included unit-testing. Tutored and assisted QA in writing extensive C++ test suite.Worked with Intel on the C# side of a client-based point of sale service that interacts with supported “shopping cart” style web pages and Javascript. Provided initial UI with MVC pattern for easy replacement later.Security work for Intel.. Snooping/anti-snooping research. This work comprised C#, Windows OS internals, mild interop, and security.Work was mostly flat-bid, and done using a modified Agile process to minimize under/over bidding on jobs, closely track progress, and provide manageable task lists with discrete, well-documented requirements.
