I have rich experiences in a wide range of software and systems over the last 15 years, the most notable skills are : 1-Linux System Administartion : I have installed, configured, repaired, and managed so many Linux systems (more than I can remember) since 2006. I started with Fedora, then centos and ubuntu. 2- Scripting (My Favorite!) : I do enjoy very much with scripting especially for automation purposes, and I am very experinced with it, on both linux (bash) and windows (autoit - batch). I can automate all the tasks even those that don't talk to the command line in windows. I made for example in past, a fully unattended Windows installation CDs that is fully customized to include all the software my customers need without asking single question ! and on Linux I use Bash scripting Language to handle almost every aspect of linux and I did wrote so many scripts for various tasks. 3- Hosting Services : I have installed and managed previously many control panels for hosting and administration, that includes Cpanel, Plesk, ISPconfig, Webmin, Usermin, AWS, DigitalOcean, rackspace, cloud providers and more ! and in addition to that I can run the hosting services directly myself with no need for a control panel. I managed standalone software like : Apache, MySQL Server, ws-ftpd, proftpd, lighttpd with fast cgi, thttpd, dovecot, postfix and other servers ! I can also build/manage any hosting services, including shared hosting, VPS and dedicated servers. 4- VPN Services: I have installed and configured many servers that provided VPN services, including PPTP and OpenVPN services. I have even created a custom control panel for the customers and link it with automation scripts I wrote to better help the client managing his customers.

I can secure your box and keep it safe and protected. I have fought malware since 2001 achieving great results like : cleaning big networks from viruses and worms and keeping it up and running in hostile environments for months with almost no downtime ! Also, I've built an app I called (Automated Malware Wizard), that would backup clinets hard drives and then GUARANTEE the cleaning of them, then update their software to close any possible vulnarables. I can customize it to you to fit your needs (If you intend to run a malware-cleaning and maintainance firm/utility). 6-Networking : I've been an ISP CEO before, and delivered internet services for more than 200 local subscriber when I worked at Hamad ISP. 7- VOIP: I am familiar with Asterisk and Asterisk GUI Installations, from scratch to fully working installation ! 8-Virtualizaion : I am very good with VMware and VirtualBox, I used them for years as a combination with hosting services. 9-Managing Mailing lists : I can manage your Email lists and make it away from SPAM lists by playing fair and square, I managed lists before, some of them got thousands of subscribers, I can clean the list also of all invalid/outdated subscribes by catching all email bounces using (my experience was with phplist script). 10- Web Development using PHP/MySQL : I can develop web pages using a mixture of several technologies including html/css/php/mysql/javascript, and I've been using this skill more and more recently. 11- I have Oracle Databases, android and Java programming experience. And Finally, I can perfectly read, write and talk English Language and you can contact me over email, sms or mobile ! I perfectly speak English Language.

    Jon M.

    Senior Sales Engineer

    United States - Tests: 7

    The age old adage of you get what you pay for has always been true of many products and services but this has never been more relevant than using oDesk freelancers. I originally singed up for oDesk to hire a freelance developer to build an application. After going through 3 different freelancers and spending over $2000 on a relatively simple app I quickly realized these discount freelancers were not able to meet my expectations. That is why I created a freelancer profile and started offering my services as an American contractor. I am located in the United States and can be contacted by phone Monday thru Friday from 9am-6pm Eastern time. I can provide phone support when needed and this is a huge advantage of working with a United States based contractor. I am currently using my IT and engineering background as a senior sales engineer selling and presenting technical products to IT departments, IT directors and C level executives. I have no problem talking to clients in person, on the phone or doing product demonstrations over a webex. I enjoy selling solutions to clients problems and showing them the value in a product. I am also involved with the marketing of products to help promote and generate leads.

    Clay Reiche Agency Contractor

    PHP,PERL Coder/Web Services Integrator

    United States - Tests: 6

    I have been successfully self employed since 1999 providing various IT related services. I started out as a Network Administrator for a Heavy Civil Construction Company in Tampa, FL providing network and desktop support to a corporate office of 75 users. I became the IT Manager of this company and oversaw several successful projects. When this company was purchased by a group company, I became an IT Specialist implementing a wide area network and a VOIP system that spanned the globe. In addition, I was responsible for managing the global team of IT staff positioned at various corporate offices and construction job sites. Since 2006 my main focus has been split between web programming and VOIP implementations with Asterisk PBX systems. My most recent accomplishment was integrating an LMS (Learning Management System) with the Magento, open source, shopping cart, giving my client the ability to sell online training courses through a very robust e-Commerce experience. On the Asterisk front, I have recently completed training for an open source predictive dialer application. This application is also very robust and used in many call centers around the world. Although most of my work these days is in programming and VOIP, I still have several desktop support customers and provide top notch service. I invest annually in LogMeIn Rescue (www.logmein.com). This is an industry leading Remote Desktop Support Tool and the only remote support package I have found to work flawless on every occasion. The fact that I am very personable, highly technical and have extensive experience managing projects, means that I am uniquely qualified to tackle almost any IT project on schedule and with a high level of technical quality. Thank you for reading and good luck with your project!
