    Independent full-stack developer / technical architect skilled in: * Ruby / Ruby on Rails (from edge to legacy) * 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) * Client-side tech (HTML5 / CSS3 / JavaScript [native / AngularJS]) * RESTful APIs implementation, integration with any third-party APIs, data harvesting from sites which do not provide an API * Social media integration (authentication, querying, publishing): Facebook, LinkedIn, YouTube, and more * Process: TDD/BDD with RSpec, Cucumber, Capybara, Zeus, Guard * Rails applications deploy, monitoring, maintenance: Heroku, Amazon EC2, Linode, Heroku) * Amazon Web Services infrastructure: EC2, S3, Glacier, Redshift,.. * Version control systems: svn, git (with GitFlow, GitHub Flow workflows) As a back-end technical architect / developer, 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, regroup, 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.
