I work a lot with bootstrap and material design. I'm proficient with CSS3 and HTML5 including newer technologies and their browser support matrices.
I love UI design and have lead design teams such as with HP as Lead UI on their Cloud Server Deployment UI - Torque.
For the last 2 years I've worked mainly with Node.js building microservices. I am currently developing a startup called IguMail, a realtime email service that uses Node.js and I've developed a Live Streaming service called StreamCatcher.org with Node.
