I've been developing Ruby/Rails apps for over 10 years. I love OSS and have contributed to many projects including Ruby and Rails. I also created several open source gems and one of them, Alba, has more than 700 stars on GitHub.
I'm passionate about refactoring, testing and meta programming. I often improve the code other developers wrote, but when I write from scratch I always do TDD to develop confidently. I'm a fan of RSpec but I use MiniTest for my gems. I love meta programming and Ruby's capacity to use meta programming to solve problems.
I'm also interested in teaching/tutoring. I joined workshops by Rails Girls more than 10 times as a coach and had some mentoring sessions with newbies.
I'm working on a new project that provides a new documentation tool with better support of RBS/RBI, better default HTML page and support of existing notations such as YARD and RDoc. It's in early stage.
