Experience
- Personal Websitehttp://kevinchen.ninja/
I created this website for myself, basically from scratch, to showcase my projects, experiences, and play around with various front-end widgets. More details about each project that I've worked on can be found there.
- ReaXn
Hackathon Project, Summer 2015. I won the Chegg Young Innovator Award at CHIMEHACK 2.
This project is a demo which enables users (in this case, girls and women) to instantly and discretely react to dangerous situations via quick gestures without unlocking their phone. - Breadcrumbs
This is an online shopping companion that automatically logs all products seen as the user browses (via a Chrome extension). It automatically sorts and categorizes products so users never have to worry about forgetting or losing information.
