    United States - Last active: 11 days ago - Tests: 1 - Portfolio: 4

    Update: Recently, I've been focusing on delivering large scaling infrastructure using AWS and Chef. Also, I've really focused on delivering CI to developers to help really bring their products to market quickly and efficiently. Since training with AWS in 2011 this has been my passion. I've built backend infrastructure for mobile applications. I've built scalable e-commerce sites using magento, wordpress etc. Whether its augmenting current windows infrastructure, migrating servers to the cloud with VPN configurations. Or building a highly scalable multi-region infrastructure, I'm your guy. Please take a look at my portfolio, I've written several blog posts about building magento infrastructure, plesk installs, docker, among others.
