    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
