    Ruby / Rails Full-Stack Architect. 8 yrs, 12k hrs, 100pct success.

    Russia - Last active: 1 day ago - Tests: 3 - Portfolio: 1

    Independent full-stack developer / technical architect skilled in: * Ruby / Ruby on Rails (from edge to legacy) * Client-side tech (HTML5 with HAML, CSS3 with SASS, JavaScript [native & libs/frameworks], jQuery, Bootstrap, and more) * Scalable, decentralized (modular) applications architecture * Databases: relational (PostgreSQL, MySQL), NoSQL (Redis, Riak, MongoDB, Neo4j), big-data-specific (Google BigQuery, Amazon Redshift) * Background jobs processing: Sidekiq, Resque, delayed_job * Message queuing: RabbitMQ (AMQP) * RESTful APIs implementation, integration with any third-party APIs (including social media APIs: Facebook, LinkedIn, YouTube, and more), data harvesting from sites which do not provide an API * Rails applications deploy, monitoring, maintenance: Heroku, Amazon EC2, Linode, Digital Ocean) * Amazon Web Services infrastructure: EC2, S3, Glacier, Redshift,.. * Process: TDD/BDD with RSpec, Cucumber, Capybara, Zeus, Guard * Version control systems: svn, git (with GitFlow, GitHub Flow workflows) As a full-stack developer / technical architect, I can develop scalable and stable multi-node server-side applications and also can evaluate your Ruby/Rails application and make suggestions on possible optimizations / refactoring / adopting best practices. As a team lead, I can divide, prioritize and delegate tasks to developers, consult developers on best practices, ensure high overal quality of software product. I like challenges, have solid skills of problem solving, do not require supervision to successfully perform my duties. Dependability is also one of my key strenghts (never left my work half-done / half-functioning). If my current rate fits your project's budget, contact me to discuss technical and other aspects — I'm looking forward to it.

    Vitaliy is one of the most talented developers we have. His expertise are .NET related technologies and JavaScript but this doesn't mean that he is not able to be the best in other areas. He likes to improve his own skills working on different projects and learn something new.It doesn't matter if it's a new technology or an API, you can be sure that he adapts to any new stuff very quickly and deliver his tasks in time. He is also a perfect team player, maybe because he likes team sports :)

    Leader of Wide Teams

    South Korea - Last active: 10 hours ago - Tests: 4 - Portfolio: 9

    I'm passionate about software craftsmanship and adapting agile practices for distributed teams. I love working with smart people to solve hard problems. My goal for the last few years has been to build a team culture in the model of Hashrocket and PivotalLabs but entirely distributed. For the last 5 years I've been leading very wide (globally distributed) teams helping them to active as close to co-located efficiency as possible. Currently I think we can get about %90 of the efficiency that could be achieved with a co-located team and that missing %10 is more than made up for by the other advantages of having a wide team. I've also been working with ruby (and rails) for almost 10 years now i.e. since rails was 1.0. In my recent projects I was the lead developer on the teams that built pawlinks.com, plateology.com, subout.com and textgen.com.
