Full-stack software engineer at Twitter

Utilized full-stack experience to create a video-level system of analytics. Contributions included everything between time-series data aggregation to front-end React development. Contributed to video advertisement interpolation in live-streaming Thursday night NFL games. Supported work to read video advertisements from and deliver usage analytics to third-party ad servers using the VAST video advertisement standard.

Full-stack software engineer at Brainshark

Worked on API authorization, data propagation, and general software.

Software Engineering Intern at Microsoft

Built a Windows mobile app, Sound Stack, that allowed users to play instruments and record songs using loops. Instruments used mobile sensors like the camera, gyroscope, compass, and of course touchscreen. Worked exclusively on the drumming instruments. Using the phone, users could "play" the drums in front of them by hitting spaces oriented around them.

Founder at CollegiateText

Built a web application to help students find deals on their class textbooks and schedule their courses. Wrote spiders to get course information from school catalogs for course scheduling and textbook matching (students could input courses and get back books, where there was no centralized book listing). At peak, had 10K visits per day during the first week of classes. The first year of operation resulted in commissions on over $120K in sales, and saving students $285K in textbook cost (with an estimated 30% price savings).
