I am professional and passionate web application and restful API developer working with Ruby On Rails for more than 10 years. I have bachelor degree(BS) in Computer Science and Engineering passed back in 2008.

I have been extensively working with Rails(version 2.x to 5.x), Ruby(1.8.x to 2.4.x), PostgreSQL, MySQL, Redis, ReactJS, AngularJS, jQuery, Ajax, Twitter Bootstrap(for responsive design), CSS. I am basically full stack developer including backend, frontend and server administration.

I work enthusiastically as devops on clouds like Amazon AWS(including EC2,S3,SES,RDS,Load balancing,Autoscaling,Elasticache,SNS,etc), Heroku, Rackspace, Digital Ocean to deploy applications from ground up to live.

I am always concern on application performance and scaling for very high traffic. For the fulltext search, I work on Sphinx,Elastic Search Engine. For better user experience, I use Sidekiq,Resque,Redis,cron for background jobs processing. For the real time web notification, I love to use Rails ActionCable.

I use Capybara, RSpec with factorygirl for Test Driven Development(TDD). I use github/bitbucket Pull Request feature with Travis/Codeship CI for Continuous Integration. I follow Agile(Kanban/Scrum) for software development and follow software design pattern while coding. I use jira/trello/pivotal tracker tremendously for task/project management stuff.

Beside web applications, I develop mobile hybrid apps(iOS/Android app) using React native and Ionic framework, javascript, AngularJS, HTML5 and CSS3.
