FuelMiner, Inc.
FuelMiner is a startup aiming to improve fuel economy for heavy vehicles via a Web application & hardware data interface.

Web application

I designed and built the FuelMiner Web frontend using Rails, Coffeescript, Foundation, and Sass. Data uploads are sent through to a Hadoop cluster in the backend for analysis and storage.


I was also responsible for provisioning and deployment for the application. I developed chef recipes to install dependencies and configuration files, and wrote capistrano tasks to automate zero-downtime deploys using unicorn, nginx, and HAProxy.

Windows client

I built a simple C# WPF client for Windows XP+, to automate the data upload process from FuelMiner's data logger hardware.
