Experience
HiTech HIPAA by Canyon Labs
HiTech HIPAA is a Ruby on Rails and React application designed to ease the burden of HIPAA compliance by keeping track of all required documentation, assets, personnel, and technologies as well as their statuses. The application acts as both an organizational tool as well as an advanced checklist in order to keep the client's compliance in line.
The project was built in collaboration with the CEO whose years of experience consulting on HIPAA compliance guided the direction of the project.
The technology used consists primarily of Ruby on Rails, with a growing portion built with React.

RMI Aware
This was designed for Remote Medical International. RMI Aware contains a database of remote operations locations and hospitals around the world and connects the users with the nearest hospitals capable of meeting their needs.
For example, you are on an oil rig in the Gulf of Mexico, and someone's injured. How do you find out which hospital can accommodate a helicopter?
This will find nearby hospitals with helipads. It also allows ships to integrate with the Marine Traffic API so that RMI Aware always knows the vessel's up-to-date location.
The version below uses mock data to protect RMI's data, so please excuse the hospitals in the ocean and the minimal styling.
