    I am a senior software engineer with over 7 years of experience. I prefer to work on ruby/rails projects but also have lots of experience developing windows software for audio/video processing in C#. Github: http://github.com/raeno My key skills: * Ruby, Rails 3, RSpec, Cucumber, Heroku, PostgreSQL, Mysql, NoSQL, MongoDB, * Javascript, Coffescript, HAML, HTML5, CSS, SASS * .NET 2.0 - 4.5, C#, WPF, XAML, WinForms, WCF, MVVM, MVC, ASP.NET, XML, SQLite * TDD, BDD, Continous Integration (TeamCity, Hudson), Nant, Rake, Git, SVN, Capybara, Nginx, * Amazon AWS (EC2, RDS, S3, ELB), Heroku, Engine Yard. I also have experience in UX, product and project management (was a head of development with 15 developers and two QA engineers in a my team) ===== Why you should hire me and not another $5/h developer? I think that quality is a key in a modern software development world with a lot of a crappy code producers and code monkeys. Thus I always try to achieve good test coverage and simple DRY design. And it's easy enough for me because i use TDD, continuous integration, continuous delivery and devops practices in my daily workflow. But quality is not only a code or design quality. I have seen many projects that were written very good in terms of code but they hadn't solved business problems. My point is that knowledge of a customer business domain is a key to better software. Being software engineer means for me not only to produce code that perfectly follow specifications but also to solve new business problems creatively. It's impossible to do if you haven't close relationship with a customer or doesn't want to listen him. That's why always use an agile approach with a daily progress tracking, frequent releases and focusing on a most important customer problems. OK, it's time to finish. If you still think that a you can better hire a ten Indian coders for my price - go and hire them. But when your project deadline start moving further and further and it all finishes with a buggy product and a spaghetti code - remember about me.  less

    To describe myself using eight words: I am a problem solver with extensive experience. As a system administrator (since 2009) I has configured and partly now maintaining servers for wm4d.com, datamojo.com, call2ru.com, serviskart.ru and other companies (more than 20 servers including VPSes). Also I consult clients and colleagues in a wide range of questions related to web development and system administration. Since 1998 till 2009 I used to work as a programmer, participated in a variety of projects including Plesk for Linux. (So, I used to work with PHP3/4/5, Perl, bash, Java (J2EE), Pascal, C, JS; I know design patterns, test-driven development, agile methodologies and so on, and so forth.) In summer of 2011 I took part in selection of the staff for one company (testing candidates' knowledge of PHP5, OOP, MySQL et cetera; more than 1000 candidates). If you need to develop UI part, I am not the right person. In the moment I am learning Ruby and I am charmed by it.  less
