Convert my Jekyll site to a Gatsby site and deploy it

My personal blog is a Jekyll site hosted on GitHub pages with several hundred pages. I need someone to convert it to a Gatsby site to take advantage of faster page load times and image responsiveness. My personal blog is based on the simple and clean Jekyll Now theme for Jekyll. The final Gatsby site should render Markdown files using my existing CSS template and retain the original URLs of my current Jekyll project. In your application, please present a few examples of Gatsby websites that you have launched and deployed in the past. Upon contract initiation, you will receive access to my website's current repository as a resource.
