Software applications which I have created or made signifigant contributions to over the years
A web application for broadcasting sports scores in real-time. There are other apps which do this, but they either have a steep learning curve or too much onboarding friction to reach a broad audience. One goal of this app was to allow people to view scores without logging in; only broadcasters need log in.
The app has two parts, an Elm front-end and a FeathersJS/MongoDB back-end. The front-end is hosted on Netlify, the back-end is hosted on Heroku, and Auth0 provides the authentication services.Scoredy Website Frontend Code Backend Code
The Remittance Manager provided a way for the client's customers to securely provide them with monthly financial information. The Remittance Manger used customer provided information to advise the customer on required reserve amounts for their insurance products. The key challenge of this project was creating customizable amortization tables; extensive testing was created to validate the ongoing correctness of the financial calculations.

The idea behind Kangaroo was to modify an Existing React application so that it could be used inside of custom native application wrappers. React native was not used because the client wanted to avoid creating dedicated user interfaces. Prior to this initiative the client used React for web clients, and a mix of Cordova and native code for mobile applications. The key challenge to this project was quickly standing up a mobile application which had all the functionality of their web applications. Additionally, the approach required creating interfaces for React applications to interact with the mobile application wrappers for handling push notifications and other native platform functionality. I was the technical lead for a team of developers on this project.

Nmond is a Ncurses based system performance monitor for Darwin (Mac OS X) written in pure C which was "forked" from nmon. The original nmon gathered system statistics by looking at /proc, which is not available on Darwin, so I had to implement system calls for all the statistics. The original program was monolithic and used global state a lot; it was modularized during the rewrite.Get the Code
This was an experimental approach to automatically schedule people for work shifts based upon their historical work patterns and stated preferences. The idea is to automatically schedule people to the shifts which they would want. The first part of the technique took a principle component analysis approach; it looked at the problem as a search problem. Historical records were put into a large matrix upon which the principle component analysis would be run. When a new unfilled shift is presented, the matrix is searched for the closest match. The second part of the technique took a max-flow, graph-based approach to creating an entire schedule.Get the Code

Squared Pics (Squared) takes a rectangular image and makes it square by removing less important parts of the photo. Areas can be manually frozen (so that they are not removed) or manually melted (so that they are more liekly to be removed). It also includes a photo editing extension, so it can be launched from within the standard Photos app.
