WordPress + Loading Speed + SSL + Optimization

United States - Last active: 2 days ago - Tests: 6

Skype: littlebizzy 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 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. My recommended services: CloudFlare (DNS) - http://goo.gl/CMyxyZ Digital Ocean (VPS) - http://goo.gl/kY6AWB MaxCDN (CDN) - http://goo.gl/qawqv6 CodeGuard (backups) - http://goo.gl/FNF2j5 DigiCert (SSL) - http://goo.gl/bW5KJf YMLP (newsletters) - http://goo.gl/YqUFHi For email, I recommend Google Apps (name@company.com) + SendGrid (for things like lost password reminders, WooCommerce notifications, etc). My oDesk policies: - Not able to sign NDAs - Not available for phone calls - Free 30 minute Skype consultation - VPS servers do not have email services - When migration begins, please pause all work - Not able to join 3rd-party project management apps - Not available for tutoring, training, or creating manuals/guides - I automatically close out hourly contracts over $500 (renewal requested) - As a policy, I only work with DO's $10/mo VPS or higher, one domain per VPS *Serious clients only please, as I'm unable to offer "budget" pricing. I leave all of my oDesk clients positive 5-star reviews on completed projects, and I offer a 100% refund guarantee ~
