Maksym Tsaplin Agency Contractor

Ruby On Rails developer

Ukraine - Tests: 5 - Portfolio: 6

I have more than 10 years of overall experience in IT – analyzing, designing and developing enterprise applications. I consider myself a backend software engineer, my core competency since 2009 is Ruby and Ruby on Rails framework. I believe that developer can be a true professional only in one technology, that’s why I don’t claim to be a multilingual programmer. But being an efficient developer means being familiar with all the technologies that are used side-by-side with your focus technology. That is why I have a strong knowledge of all the instruments that are usually used with Ruby on Rails: Javascript, CSS, HTML, Rspec, PostgreSQL, MySQL, MongoDB, etc. My skills summary: - Full software development cycle from OO Analysis/Design to implementation, testing, deployment and support; - Extensive project architecture designing, leading the development of different types of projects; - Management and coordination of team performance: I am able to effectively organize and prioritize multiple complex tasks, interact creatively and achieve results in a dynamic environment; - Building internal technical teams and managing offshore groups; I think that developer should be self-taught and have a passion to make things perfectly. I believe it’s the greatest feeling to see that your final product is ideal.

Marlon W.

Ruby and Rails Developer

Jamaica - Tests: 4 - Portfolio: 5

I started programming in 2001. My first programming assignment was done using Pascal. Since then I have been exposed to quite a few other programming languages and frameworks. I have worked on a number of Enterprise Java projects and as such I developed a liking for Object Oriented programming and its principles. In 2009 I started to learn the Ruby on Rails framework, which I find to be one the most developer friendly frameworks. On oDesk I wish to take on challenging/interesting projects using the Ruby on Rails framework. I’m a firm believer in the TDD and DRY approach to programming.
