    I started programming computers when I was eight years old, and, over the last 30 years, I've realized that I am, well, a programmer. That said, I do have the "people skills" necessary to remain competitive in the world of programming. When needed, I'm a "sit in the corner and program til the wee hours of the morning geek"... otherwise, I'm just a "fun to talk to, easy to get along with normal person". I have always enjoyed the challenge of creating interactive software. With the birth of the modern Internet, I found a new love in web development and web programming. I face every new piece of code as a fresh new beginning... a chance to do it even better, while, still using "what works" from the past. My objective, here at oDesk, it to provide potential employers with my expertise in the field of website desgin, development, and programming.  less

    For long term projects hourly rate is negotiable. Couple reasons why hire me: * I'm skilled, smart and an independent LAMP developer able to fit any demands. * I've created a lot of websites using PHP/MySQL including sites for large companies, e-commerce and multimedia sites. * I'm familiar with large amount of modern web services. * I'm custom code developer and I use modern frameworks like CodeIgniter, Laravel, CakePHP to speed up development process. I do not work with existing CMS frameworks like Drupal or Joomla. * My working hours are very flexible. * I've started developing web applications 12 years ago. * Unlike other great developers I know how important is to keep an open communication channel. * I can assure you that I'm efficient and spending time purely on planning and development. I'm never charging for anything not directly connected with project (for example filling the knowledge gaps). * I'm able to follow your website needs, bringing exactly what you need. You're not just getting an efficient developer, but also someone that will help you with project in general (excluding graphic design as I'm not good in this area). When you need not only coder, but also someone that thinks logically/analytically, I'm your guy. * In the end I have over 3000+ hours on oDesk with contract value over $100,000  less

    Hi there, I am a 30 years certified System Administrator you wish getting help from : I am an LPI(101 & 102),RHCE certified, Automation king!! 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. (see the following picture): http://img687.imageshack.us/i/screenshotrsl.png/ And besides I am the solo developer of vpnplatform (vpnplatform.org/team) ;) and my clients consider me the best VPN guy on odesk. 5- Figting Malware: I can get your windows box clean even from the hidden malware and spyware trojans. 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- PHP/MySQL : I can develop web pages using a mixture of several technologies including html/css/php/mysql/javascript. 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. I am ready to move to your job location if needed. I respect my work and give it every effort I can while keeping job's secrets secured and not to be shared with any 3rd party. You may see my attached C.V. and my odesk profile at: https://www.odesk.com/users/~~9b6150fc1d75d477 Note: I can adjust my availability time to suite your needs. Best wishes Ahmad  less
