I'm a solopreneur creating tools and products which serve athletes and fitness enthusiasts.• I make FitEdit, an open-source web, desktop, and mobile app for editing and managing fitness data. It runs on Windows, macOS, Linux, Android, and iOS. The frontend is built in XAML on Avalonia UI. The backend is built in C# on ASP.NET Core, Postgres, Supabase, and hosted on fly.io. The backend integrates with Garmin, Strava, Stripe, and SendGrid. I'm an expert on the Garmin FIT and TCX file formats. https://www.fitedit.io https://github.com/endurabyte/FitEdit• I reverse-engineered commercial treadmill microcontroller signals using logic analyzers for the purpose of exposing the speed and incline controls via a web service. Designed and fabricated a printed circuit board to interface the treadmill with a Raspberry Pi. A Xamarin.Forms (and later .NET MAUI) app runs on Android and iOS to command the treadmill through a structured workout without the user pressing any physical controls. https://github.com/nref/treadmill• Wrote a library for editing Garmin Training Center XML (TCX) files: https://github.com/nref/tcxmill

I'm improving global insights to weather and climate through design, implementation, and test of Climavision web apps and backend services. I wear a lot of hats here:- Mentor. I'm upleveling our other engineers with daily 1-on-1 pair programming, frequent in-depth code reviews, and weekly brown bag presentations. - Advocate and Bridge. If an engineer needs something challenging done, I either help tackle it directly, or I organize resources to help.- QA Solutions Architect. I'm a stickler for upfront quality and test automation. I've bootstrapped our product QA capability from zero unit tests to a robust suite of automated user and functional tests, and I've rallied a following of other engineers to do the same.- Software Designer. I'm an evangelist for simple, easy-to-understand code that works right and keeps working right. - Product Support Engineer. I'll gladly get on the phone with any customer who's having a hard time.- Performance Bottleneck Attack Droid. I've systematically targeted slowdowns in our production apps to make them blazing fast and responsive.

Working 100% remotely, in a blazingly fast time to market of two years, I and my team created RayCommand, a suite of software services and user interfaces which support the daily operations of radiation therapy centers. As an experienced reader and writer of software and robotics domain expert, I improved the state of cancer radiation therapy by supporting the robotic positioning aspects of the new RayCommand product, which together with RayStation presents a vertical integration of both treatment planning and execution. Technical topics included robot kinematics, collision avoidance, motion planning, 3D graphics, C#, WPF and XAML, C#, and ASP.NET SignalR.

Improved patient treatment outcomes at hospitals and medical practices nationwide by reducing communication delays and interruptions between practitioners and their care teams.• Development, test, and maintenance of microservices according to Domain-Driven design principles and onion architecture. • Developed for multiple platforms in C# using both Visual Studio in Windows and Rider in Ubuntu. Proficient with command-line tooling such as vim, Git, dotnet CLI, Docker, and docker-compose. • Deployed to heterogeneous environments including on-premise datacenters and AWS using continuous integration and build automation.• Contributed to unit and integration test coverage and to end-to-end test automation. • Comfortable with Inversion of Control principles such as Dependency Injection using frameworks such as Ninject, StructureMap, Autofac, and Lamar.• Became an expert converting .NET Framework web services to .NET Core.• Worked on Agile SCRUM teams adhering to Agile practices such as sprint planning, storypoint estimation, daily standups, sprint retrospectives, and sprint reviews with stakeholders. • Communicated daily with remote teammates in different timezones and countries.

Improved the state of cancer treatment through the design, implementation, and testing of software services in C# supporting the robotic positioning aspects of the ProNova SC360 product. • The software, which is in use at all of the Provision Centers for Proton Therapy, provides an ease of use unprecedented in the Radiation Therapy industry while providing an unmatched level of safety. Given a target position, a patient-carrying robotic arm is directed through an automatically improvised trajectory while avoiding obstacles and obeying position, velocity, and acceleration constraints. The movement is guaranteed to be collision-free.• Technical topics included robot kinematics, kinematic chains, Denavit-Hartenberg parameters, forward and inverse position and velocity calculation, trajectory planning and optimization, linear systems of equations, collision avoidance, motion control, simulation, and 3D graphical visualization.• Contributed to rigorous standards compliance, risk anaylsis, and satisfaction of regulatory burden.• Became proficient in Windows desktop frontend development using XAML and WPF. Became proficient with RESTful Web APIs and WCF. Developed a knowledge of and intuition for good software architecture. Used IBM Rational Team Concert and Jazz for source control, requirements planning, documentation, and test.
