I have been a LAMP stack developer since 2003. I have worked primarily with Object Oriented PHP and MySQL during that time. I am competent as a Linux Administrator and an expert Web Developer. I most enjoy using Laravel and Vue at this point in my career but am comfortable in nearly any LAMP/LEMP based environment. I enjoy always learning and finding the best solution to a problem. Here is a list of some of the things I’m familiar with: Object Oriented PHP MySQL & Performance Tuning of MySQL Maria DB Laravel 5+ Vue.js AngularJS 1 & 2 WordPress HTML5/HTML/XHTML JavaScript CSS3/CSS Git XML AJAX SOAP REST fPDF ImageMagick PDO ADODB PHP Linux - (Ubuntu & CentOS) Apache2 Nginx Flexbox MongoDB Composer NPM Google Maps Javascript API YouTube Javascript API Google Analytics Mandrill Email API Twitter API Flickr API USGS Water Data SnowTel StrongLoop/Loopback Parse (by Facebook) and its migration process to Mongo Handlebars.js jQuery jQuery UI YUI2 (with some YUI3) TinyMCE

US-based, US/Eastern time zone. Ultimately, I'm looking for permanent, full-time employment (in the $130-180K/USD or Euro range). Clean passport, and willing to relocate to Europe (Malta or northern Italy preferred). In the meantime, I'm available for gigs at a rate of $125/hr. I've provided Unix/Linux consulting for businesses for more than 30 years. I've been a Linux Subject Matter Expert since 1994, with various flavors of Unix going back to 1986. I've been a rescue ninja at multiple Datacenters and Web Hosting startups worldwide. I introduced Linux to the US Federal Government in 2002, and after moving away from Compaq and Sun, worked with IBM/Lenovo assisting the development of IBM's high-density X6 server line. I've worked in/for/with most major world datacenters in engineering, design, and systems administration roles. I've been a WordPress-centric Web Developer since 2003, and often work adding features and maintaining WordPress sites (e.g. minor PHP Development). I'm also a former WHM/cPanel Certified Support Partner, as well as a former WordFence Manual Malware Removal Ninja. NOTE: Please do not try and use me as a "consultant" to teach you Linux. I'm here to DO WORK, and my rate is as it is because of my EXPERIENCE. And while it may seem expensive, think about paying me an hour or two to fix something, rather than paying five or six different people $50 each to fix a problem that never seems to get fixed. ALSO NOTE: If you want a trustworthy administrator, I'm your guy. I have a solid reputation, multiple security clearances, and I'm easily found on LinkedIn with rave reviews from former employers. Keep that in mind, because SCREEN SHARES DO NOT WORK. I type 90wpm on a slow day, and use a Linux Shell to do work --- I type too fast, and Screensharing hinders progress. Trust goes both ways!
