I have been working with Ruby on Rails since 2012. I do have mastery skill and knowledge in Ruby. To build a complete web application using RoR framework I have used almost every well-known technologies or gems or tools in my whole career eg. for database PostgresSQL, for background job Sidekiq or RabitMQ, for distribute search engine Elasticsearch and many many more. As a full-stack developer I am skilled in frontend development too. I have huge experience to work on JS in typeScript in StimulusJS and also in ReactJS.
I always believe in TDD approach. And always delivery my code with 100% test coverage. I have huge experience in wiring unit test using RSpec, Minitest and for integration test I love to write test code in Cypress
