Took over and lead a project to commissioning fixtures in a stairwell without the need for human interaction other than starting the application. Supported existing code while also re-writing the application to add a more information rich user interface and optimizing the code to allow application to execute in < 1 min which was down from 5 minutes.

Developed an application to receive data via serial connection from a ultra-wide band (UWB) sensor, which received messages from the other anchor sensors, processed the data, and determined the location of tags in relation to the anchor sensors. Once the location was determined the positions were sent to an indoor positioning system via initially a REST API call and then later via Microsoft Event Hub.

Wrote a proof-of-concept for an Amazon Alexa skill that could control Acuity Brands fixtures via an Amazon echo. The skill allowed for the control of non-smart light fixtures via a micro-controller with firmware (written by another developer) and a protocol developed by me and the firmware engineer.

Lead the effort to replace the existing project process using a modified version of Agile. Myself and another engineer researched and tested various project planning softwares to ensure that the software selected fit the Innovation group's needs. Once a project planning software was selected, I defined the new processes for the Innovation group to plan, track, and report on the status of projects. Once the new project planning software was rolled out, I acted as administrator and trainer for the rest of the Innovation group.

Developed and implemented numerous in-house utility applications as well as libraries for faster development:

• Created an application to allow for logging and sending data over a serial connection for the firmware engineers to use to test their firmware.
• Created an application that created messages to send to a micro-controller based on user input.

Tech: C# (.NET Framework), Windows, SVN, MongoDB, WCF

Worked on several proof-of-concept projects, which included demonstrating that tape media storage could be backed up using our product.

Worked on our build server (Jet Brains TeamCity), which included developing several Java plugins and completely re-organizing our build configurations.

Worked with the documentation team as well as the GUI team to aid in integrating context-sensitive help within the frontend of our product. This included localized context-sensitive help, which had never been delivered prior to my work.

Setup and configured a development demo environment. This demo environment consisted of four virtual machines running on an ESXi server in an off-site data warehouse.

Designed and implemented several in-house utilities:

• Created a localization utility to aid in working with resource files within our repositories. The utility allowed for easier gathering of resources (producing a zip file containing the resources and the directory structure of their source repository).
• Created a database change generator that allowed for data to be stored in a specified database table at a configured interval. In addition, the database change generator allowed modification of a randomly selected existing row on the configured iteration.

Tech: C# (.NET Framework), VB .NET, Windows, SVN

Extracted a proof-of-concept data engine from flagship code line (VB) and wrapped it in C# so that engine could be offered as an alternative to existing data engine.
