About Geoffrey Liu

With over 7 years of work experience, I am a versatile and creative professional with deep experience in iOS development as well as in music education and sacred music. At Groupon and PayPal, I developed innovative features for consumer-facing apps, reaching over 200 million users worldwide. I have been involved in the rebranding of the app experience, as well as creating new and unique experiences centered around eCommerce. In addition to feature development, I have also lead technical initiatives such as reducing technical debt and ensuring code quality. I enjoy collaborating with a talented and diverse team of engineers, designers, and product managers, and I am always eager to learn new technologies and best practices.Outside of my software engineering role, I am currently the organist at Kent United Methodist Church and an instructor and staff pianist at The Key to Change, a nonprofit organization that provides violin and viola lessons to students of color and low-income backgrounds. I am motivated by the mission of both organizations to foster a diverse and inclusive community through music and education, and I bring my skills, enthusiasm, and dedication to every project and performance.
