    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.
