Sandra Jean V. Chua (Sacha)
Technology evangelist

I make technology human.

With a deep technical background and strong communication and interpersonal skills, I can connect with both technical and non-technical people. I love showing how technology fits into people's lives and how people can make the most of products and services. I love connecting with people, and I enjoy writing and public speaking as much as I enjoy coding.
