About Me

I grew up in trailor parks and small towns in Mississippi. I moved to study Computer Science at California State University - Sacramento in 2012. I am now residing, and in love with, Seattle, WA. I am forever-grateful for both sets of my grandparents whom provided access to and encouraged my computer interests as a child, as well as the many people who have invested into, and believed in me. While away from the keyboard I enjoy sailing, trying all the pho resturants in town, backpacking to new countries, and attemping to limit how many hobbies I pick up!

I am currently the engineering manager at Goodleap, prev. Loanpal, for the largest teams in the consumer finance org. I was engineering employee #4 and have since hired most of all core engineering operations leaders and individual contributors. I have been gratefully mentored by some of the smartest people I have ever met while leading the organization to a now multi-billion-dollar, humanitarian-driven, enterprise.

React Node.js C# Unity3D Hackathon

This no-name project was the first place winner of a 12-hour game jam at CSUS - ACM that combined my knowledge of web technologies and desktop game development to create a local multiplayer party game in which the controllers are any web-connected device, such as a cell phone. The controllers of the game were built with react; they talk to a Node.js and backend which keep the game state synced with the Unity3D game client.
