About

Hi there! I'm Cassidy Williams, and I am a software engineer, dev advocate, startup advisor, and investor! I have a weekly newsletter at cassidoo.co/newsletter, where I have tech news, interview practice, jokes, and more. I was featured in Glamour magazine as one of the 35 Women Under 35 Who Are Changing the Tech Industry, and I starred in the documentary Big Dream (www.bigdreammovement.com), which focuses on women who are breaking barriers and overcoming personal challenges to follow their passion in science, math, computing & engineering. I love public speaking and have done so at meet-ups, hackathons, and events like the Grace Hopper Celebration for Women in Computing, the National Center for Women & IT Summit, SXSW, TEDxDesMoines, the United Nations, and the U.S. Science and Engineering Festival, and hundreds more. When I'm not coding or speaking, I pass the time by playing music and hanging out with my (also techy) sister, Camryn. I want to inspire generations of STEM students to be the best they can be! Take a look at cassidoo.co for more about me!
