My portfolio site is currently built with GatsbyJS and Contentful CMS with Netlify for CI/Hosting.
GatsbyJS (which uses ReactJS) is used for templating the site, with Contentful CMS for managing the content. Netlify is used for automatically building and redeploying the site whenever a change is made to either the Git repository or the content on Contentful. Netlify is also used for hosting my site.
