    United States - Last active: 1 day ago - Tests: 6

    My specialty is loading speed and on-site optimization re: WordPress websites. Specifically, I can optimize your DNS records, web server (VPS), WordPress (cache, plugins, etc) and source code (HTML, CSS, JS, fonts, images, etc) to be more efficient and secure. I am well versed in WordPress (#1 on oDesk), WooCommerce, Nginx servers, CloudFlare, SSL certificates, and SEO. Loading speed and SSL are now two of the biggest factors in SEO according to Google, whose robots are constantly analyzing the quality of your website. Don't get left behind by the competition. https://www.littlebizzy.com/seo-is-dead (case study) Whether you need a one-time consultation, or fully managed WordPress hosting, I am not shy in making important suggestions that will improve the experience of your customers. I can work alone as a project manager of sorts or alongside your current team members. I stay in close touch with your team via email, Google Docs, and Skype.
