You will get Ruby on Rails application stack upgrade
Project details
Upgrade your Ruby on Rails application to the latest version for enhanced performance, security, and modern features like Turbo and Turbo Stream! With 4+ years of experience in full-stack development, I specialize in upgrading Rails applications, ensuring backward compatibility, minimizing downtime, and addressing challenges during the upgrade process. This includes updating the Ruby version, Rails framework, and associated gems.
I refactor deprecated code, optimize database queries, and run automated tests to ensure stability and efficiency post-upgrade. I also incorporate Turbo for front-end optimization, Turbo Stream for real-time updates and JavaScript libraries (React.js, Vue.js) for responsive interfaces.
My deployment expertise includes Heroku, AWS, and DigitalOcean, ensuring smooth transitions and optimal performance. Skilled in Capistrano for automated deployments, I streamline processes and reduce errors. I ensure compatibility with popular gems like Devise, ActiveStorage, Pundit, and Sidekiq.
Whether upgrading from Rails 4, 5, 6, or earlier to Rails 7, I’ll future-proof your app, making it faster, more secure, and ready to leverage the latest Rails and cloud deployment.

Migrate an existing site to github pages.
The requested work was completed sooner than expected time. Zahid understood the requirements well, he showed initiatives, and presented solutions. I'll definitely prefer to work with him again.
