Hello. From an early age, I learned the program with the education and support of my parents. Currently, as a Ruby on Rails Expert, I is well versed in various technologies including Ruby on Rails, React, Angular, Vue,Php/Laravel, Flask, Django, AWS,Git and has developed many projects I have recently developed a website with file sharing using Ruby on Rails. If the function of the site can be broadly divided, it is the FileSharing part and the Account management part. Angular13 was used as the frontend, and Ruby 2.7.2 and Rails 6.1.4.7 were used as the backend. I used PostgreSQL as the database of the project. And improved authentication with Devise Gem. Imagemagick, Poppler-utiles, Libsqlite3-dev, and mailcatcher were used as third-party libraries for site development. I have used Google APIs, Twilio, IBAN, and Swift APIs as third-party APIs. RSpec was used for inspection. So far, My clients have never been frustrated with my work and I hope to make you one of them. Please confirm that I am one of the best fits for you and drop me a message for further discussion. Thanks and Best Regards.
