HTML, CSS, SASS: The essentials. I have many years of experience designing for web from concept to reality with a mobile-first mentality.
JAVASCRIPT, VUEJS: This is where the fun begins. Javascript and a reactive framework are the backbone for most of my projects. Interactivity and responsiveness are very important in today's web world.
NODEJS, GITHUB, ATOM: These are my personal programs/frameworks of choice that enable my work and allow me to craft a working product. I prefer running the NodeJS module ExpressJS on a server when necessary for the job.
