At home we are proud to be using:
Ruby on Rails
Ruby and its outstanding framework, Rails, is the predilect language I've used on my projects and which I prefer to work on.
Git and Github
The Version Control System is maybe one of the more important tools that any Developer should learn.
Heroku
I like to test and deploy my apps on Heroku. Its free tier is always enough for any hobbyist project and can scale to production-sized apps easily.
Some of my projects:
TwitterBot
This fancy bot just remind you to clean the air conditioner filter each month. It is written in Ruby and deployed on Heroku.
Learn-to-Git
This is a colaborative and Open Source project to teach and learn the Git basis. It is deployed on Netlify.
RapaNui Cargo
RapaNui App consists in a back office system for on-site office work and an Api to check packages statuses. Work on an already in production Ruby on Rails project, some fixes and new functions added.
