Summary
👤
SeniorGeorge Chang is a software developer with 14 years of experience building front-end and full-stack web applications across education, ML tooling, and startups in the Bay Area. Currently at CK-12 Foundation, he brings prior senior frontend experience from Lacuna Technologies and full-stack delivery at ALCAL Industries, with shorter stints at DataRobot and Frequence that sharpened his product-facing engineering skills. He pairs a practical engineering mindset with real-world customer experience from roles in sales and media, including closing high-value ad deals at Yelp and work in post production and journalism early in his career. George’s background as a barista who coded on the side hints at a pragmatic, service-oriented approach to engineering and an ability to thrive in hands-on, fast-paced environments. Trained at USC and App Academy, he blends formal business schooling with intensive full-stack bootcamp training, making him equally comfortable discussing product strategy and shipping UI code. He is based in San Francisco and focuses on delivering polished, user-centered interfaces that connect technical depth with business impact.
