Marshall Humphries — Senior Front-End Developer

I am a senior front-end developer with more than 15 years of experience working with stakeholders and designers to turn requirements and sketches into beautiful code. I enjoy creating sharp-looking, fast, accessible, and fully-responsive web applications and web sites that are easy to maintain and provide a great experience for the customers who use them regardless of the platform or device they choose.

I am accomplished in the rapid development of responsive, enterprise-level software using modern JavaScript frameworks with a focus on semantic, accessible, and localizable HTML and CSS. Excellent spoken and written communication skills make me an effective team lead.
