About Me

I am a Senior Frontend Developer bridging the gap between graphical design and technical implementation of websites, applications and core components - defining how solutions look and work. I have a strong work ethic for developing elegant code, frontend components and responsive customer experiences on projects - staying informed of best practices, new tools and libraries.
