Saige is an entirely self-taught computer programmer whose love for programming started at the age of 16. At 18, he decided to start his own business offering computer repair and website development for small local businesses. After exiting that business, he has enjoyed working with clients to fulfill their business goals and objectives as a self-employed software engineer. Eventually, Saige found his way into roles at large tech companies such as Twitter and Google.

Insider Trading API

Built an API that scrapes the EDGAR database for the SEC filings of publicly traded companies. Using this information, I was able to alert when a company's executives or large shareholders would purchase or sell a portion of their ownership in the company. This information is important to traders because it gives insight into how confident the insiders are about their company at its current share price.

Home Automation

Built a server that could accept commands and pass them off to the proper home automation products. Using a React Native mobile app that I developed for this, I can turn on my coffee pot from anywhere in the world.

Motion Detection Algorithm

Built an algorithm using OpenCV that, given a camera feed or the IP of a camera, could generate alerts, highlight motion, and record times that motion occurred. The algorithm applies a Gaussian blur, uses a diff algorithm, draws contours around the differences, and then finds their area to determine the frames with motion. You can use one of the following for the diff algorithms: two frames difference, "background"
frame difference, or BackgroundSubtractorMOG2.
