    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

    In my career; I developed many Projects based on open source technologies like Linux, Qt, MySQL, Java. Projects were mainly of a medical nature; ranging from embedded to desktop to web applications. What always interests me are embedded projects, projects of complex functionality that adds emphasis on usability and user experience. Also Qt projects; I'm fascinated by this toolkit. Generally I have a good OOA&D; skills; UML and design patterns knowledge, and always like to read about different programming paradigms.

    Microsoft Certified | Senior Developer | Team Leader

    Australia - Tests: 9 - Portfolio: 3

    Over the last 15 years I have continued to develop my career, skillset, knowledge and experience. The last couple of years, upwork has introduced me to a great number of great people and projects. Two of these projects will be briefly outlined below. The first was designing and implementing a 4 million hits / day infrastructure to handle advertising banners. This client had a business requirement to greatly extend the reach of the live infrastructure. This project was completed in PHP / MySQL and is currently hosted on a cloud platform. This project scales automatically as required to handle any variation in the daily load. The final project was a hospital scheduling task. This client worked for a hospital and had over 30 different scheduling rules for every time-slot. The client used to do this manually and it took hours every week. I came up with a VBA based solution that would automate this task. On completion, the task took about 20 seconds to execute and correctly assigned all time-slots to the correct hospital resources. I would like to continue to be exposed to new and different challenges, that will further develop my skills and career. I also really enjoy making new contacts on the upwork network. I look forward to the many varied opportunities and roles that upwork offers.
