Web Developer

Software Development Intern

2015 - 2015
Invoca, LLC
  • Contributed to Backdraft, a wrapper around Backbone.js providing jQuery DataTables integration and Plugin Framework.
  • Collaborated with a Scrum team to evaluate and track user stories through development.
  • Participated in a company hackathon, where my team won first place for creating a new reporting system.
Technologies: DataTables

An open-source IDE for working with Bethesda game files with an extensible module system. Built with AngularJS, Node.js, and Electron, it binds a Delphi DLL through a native node addon and provides tools for viewing, editing, and generating Bethesda Plugin Files, Papyrus script files, and Bethesda archive files.

Contributed to an open-source repository to improve the file-speed extraction. The approach used by the library was inefficient because each time it directed 7-zip to extract a single entry, which caused it to seek that entry in the archive, decompressing as it seeks. This results in an O(n log n) extraction time ignoring overhead. The extraction time for several archives I was extracting went from more than 60 seconds to around 3 seconds with these changes.

File Format Parser
A Node.js package that provides an API for reading and writing binary file formats. Uses an innovative data schema approach to make defining file formats easy and flexible.

A C++ volumetric graphics engine built using SDL. Used to generate volumetric representations of fractal objects. Capable of generating and navigating around 3D fractals with billions of voxels and using raycasting to generate images.

EcoNode — Environmentally Aware Mesh Network
Eco Node uses a live mesh network of 2.4 GHz radios to relay local weather, plant conditions, and water consumption information to a usable database. I developed the software to receive the radio transmissions, push them to Firebase, and build the front-end data display.
