Hello,
My name is Leny, i have been working as a developer since 2013, I started as a Ruby on Rails developer, around mid 2016 i decided to focus on the frontend.
A deep understanding of backend development requirement makes me a better team mate, friction between frontend and backend teams slows down project a lot.
I care about accessibility, you should too because it opens your project to around 15% of the population because anyone can develop disabilities because it can prevent law suits because it is the right thing to do :)
