Javascript and Ruby on Rails Developer
$35.00/hr
Passionate developer with 5 years of experience using HTML, CSS, JavaScript, and Ruby on Rails to build all aspects of user experiences and user interfaces. Lately, I'm very focused on Hotwire and Ruby on Rails.
For the past 4 years, I was working on frontend development on a large Ruby on Rails application for the best knowledge management software in the world - Helpjuice . During this period of time, I was responsible for the entire front-end for the app. I collaborated very closely with design and product to produce the most user-friendly and aesthetically pleasing UI/UX from start to finish.
Some of the achievements in this period of time:
- Improved landing page speed score from 25 to 99 on google page speed test
- Moved Helpjuice to the top on the Google Search Rankings
- Successfully moved frontend legacy code from CoffeeScript to Stimulus controllers
- Successfully integrated CK Editor and I was able to extend the editor by creating more than 15 custom plugins for our needs.
