In this course, David Morales takes a hands-on approach to guide you through techniques and tools you can use to fix bugs with ease. Bugs may be unavoidable, but learning David’s bug detection and troubleshooting techniques can give you confidence and skills that are in demand today for any Ruby on Rails developer.

Instructor's Courses

I'm a web developer working for startups and agencies. I use Ruby on Rails as my framework of choice for backend development. For frontend I like to use tools like Hotwire and Tailwind CSS. I have been teaching on-site to companies for 6 years, enjoying the experience very much. I created my first online course in 2013, and in 2022 I became a LinkedIn Learning instructor.
