    Ruben Z.

    Php Developer

    Armenia - Tests: 2

    Hi! I'm currently looking for a challenges and long-term partnership with highly-qualified professional team. If you feel like we can collaborate, please, contact me. The following keywords are important for me: High-load, Algorithms, big O notation, Data Structures, Application security, Pentest, Code Complete. I'm not afraid of overtime and working under high pressure, but I prefer balanced and productive workflow. Practicing of Agile/Scrum is welcomed. Here is a short list of technologies/tools I'm familiar or had an experience in past: [General] PHP JavaScript MySQL PostgreSQL MongoDB Redis Memcached C#.NET TCL C/C++ [CMS/CMF] Magento Joomla WordPress Drupal (a bit) [Frameworks] Yii Zend Framework Symfony (a bit) JQuery Underscore MooTools (a bit) AngularJS Raphael VanillaJS :) 960gs Bootstrap [Other stuff] XML/XSL Phonegap Mustache NodeJS nginx MeteorJS If I'll try to list everything here it will be a very long list. So these are enough to illustrate the sphere of my expertise. Out of this list I want also mention that I had a lot of experience with old-fashioned things like Delphi, Borland C, Pascal etc. I'd love to learn/practice new/non-standard technologies and non-mainstream things. I'll be happy to join a project which uses Python, Ruby, Go, Haskell, Scala or Fortran /yeah, I adore Fortran :)/. Projects related Science, Charity and/or Armenian Diaspora - will have a discount. It will be a pleasure to help people to do good things. Open-source is my passion. Previously I had no enough room to complete my pet-projects. So it will be very good to join to any open-source project and have my code available to everyone. I'm crazy for application security. For me it is the one of the most important things. I'm an active member of a local OWASP chapter. It will be great to have an opportunity to help to increase the security of your project. I'll definitely want to join you if your project is related to Cryptography. I'm working under Linux environment (Ubuntu/Mint). Vim is my first love. If it is not principal to use an IDE, I'll prefer to get things done in Vim. Git/SVN are mandatory for me - the very first thing I do on a new project is to create a new repo. :) That's all. Thanks for reading. If you have any questions or proposals - feel free to contact me. --- "An algorithm must be seen to be believed." Donald Knuth
