    I am a Russian-based Web developer. I do high-load project development and optimization, and I enjoy my work. My primary focus is backend development, but I also have strong knowledge of JavaScript, HTML5, Node.Js programming. In high-load applications, I use memcache and memcached, and I build dedicated caches into applications that use a lot of data, that we can group into a third table. For databases, I usually use MySQL, NoSQL, MongoDb or Cassandra. For optimization of the database I can use sharding, partitioning, and replication – (depending on the application), and I will set correct indexes, implement query optimization, and add triggers and storage procedures. Also I use APC (alternative PHP Cache), ESI FPC (full-page cache) in projects, along with Nginx + php-fpm, eAccelerator, Sphinx, and MySQL in tmpfs. For file storage I use CDNs such as Amazon S3 or Rackspace CDN. To achieve a more efficient project structure, in a shorter time period and to a higher quality, I prefer to use such frameworks as Symfony and Zend. Please feel free to discuss all the details of your project with me and let me know if you are interested in my services. I'd also like to mention that if you have a complex project to develop, we are able to assign additional programmers to the project. I look forward to working with you.  less
