Officiating soccer on the weekends has been an incredible and unexpected learning experience. I have developed skills in teamwork and communication that I hold invaluable in all parts of my life. Being laser-focused on a play while visually communicating with co-referees while diffusing coaches and parents while being responsible for making split-second decisions with the highest degree of precision and confidence is an experience I wouldn't trade for anything.

WellPower strived to revolutionize water delivery for the developing world. I led the full-stack development of WellPower’s order management system and worked with a small team to build WellPower’s mobile app.

I aided in the hardware architecture prototyping of WellPower's industrial solar-powered water filtration system built from recycled solar panels, batteries, and water pumps.

VRTX explored the cutting edge of virtual reality, bringing the latest technological developments to the public.

Waking up at 4 a.m. for an 8 hour morning shift before EE lectures kicked my butt. The time I spent at Starbucks taught me how to work efficiently and make every second count. I also learned the value of a good night's rest. I was recognized for superior craftsmanship and customer service.
