OnStar Mobile Number Management System

I developed the in-vehicle LTE capabilities for GM's OnStar department using server-side Java to connect to mobile carrier APIs. The telephony carrier management was developed for 34 countries in Europe and Mexico to extend OnStar's capabilities into those geographic regions. JUnit (unit testing framework) was used on all functionalities and the teams participated in paired-programming to ensure the highest code quality.

OnStar | GAA

The Global Advisory Application (GAA) was a legacy application which was redesigned in Polymer to be used by the OnStar call center whenever a GM customer clicked the OnStar button within a vehicle. I was responsible for redesigning a screen for a Polymer component which handled payment methods for the customer to be kept on file.

Rx Member Hybrid Application

A hybrid mobile application built on AngularJS/Ionic. This application was designed, architected, and developed from the ground up in order to serve thousands of clients.

TEAManager™

A fantasy football application that was built with Polymer to give users a cohesive experience between devices. This project allowed users to test different scenarios and iterations of player lineups in order to generate winning DFS league lineups. The application and website were both designed and developed by myself.

6ix | Personal Training Application (Website)

I designed and developed a website for 6ix LLC, using Polymer 2.0 to showcase their three different mobile applications. This website was designed to be responsive and quick, utilizing Polymer as a single-page application to give users the best web experience available to them.

Daitio

Daitio was an application/MVP developed using Spring MVC over the greater part of a year. The exciting technology was focused on grabbing information from multiple wearable devices to provide doctors with insight on how to manage and control the progression of chronic metabolic diseases.

IT Test Drive

I developed a custom solution (HTML, CSS, JavaScript) that was built on top of SharePoint's document library to provide GM with the ability to pilot beta software to its IT department. Business users would upload text/images to different libraries within SharePoint which would then be accessed with REST APIs to display in a user-friendly way.

Service Request Tracker

The SRT tool was developed for GM using C# and the .NET framework to allow any number of internal departments to put in service requests for projects requiring a substantial budget. These requests would be passed on through an approval process and would allow the user to check the status of their request at any time.

Mars Rover | Polymer

This program was built with Polymer and showcases aspects of reusable web components, data binding, HTML, and JavaScript. To get going, simply drop the "dist" folder onto a server and run the index.html.

The "dist" folder is a vulcanized version of the code which can be found under the "app" folder. Navigate to "app/elements/mars-rover" to see the HTML, JavaScript, and CSS files that make up the "mars-rover" element. The rest of the "app" folder contains necessary, reusable components from Polymer as well as the structured layout from a Polymer-Starter-Kit-Plus project.

TCO Tool

I led the delivery and development of a SPA tool using Angular 6 with a .NET Core back end to compare the cost of an application over its lifecycle vs. a competitor model.

Project Details:
• Generated reports and comparisons to show visualizations of the total costs.
• Automated data imports to speed up the process of manual data entry.
• Created a library of previous studies to allow all users to duplicate or view studies deemed re-usable by an admin.
• Developed an admin dashboard to allow admins the ability to see different studies created, users accessing the tool, and total monetary value generated and saved from using the application.
