I've been designing and building sites and apps for over 10 years. My current favorite tools are RoR, cordova and ionic. I love meeting new people and solving new problems. Looking forward to helping you learn and grow.
I have worked in php the longest, and at Killit I built a custom CMS platform that still hosts 20 sights today. It was basically an alternative platform to wordpress, drupal, joomla. I have tons of sample code to share as a mentor.
I started with rails 4 years ago and have since built a whole cms, 20+ sites, a few gems, and have my whole current company using Rails as the backend. We are using everything from rspec and selenium to providing cms tools for admins and api's for mobile apps.
I've integrated with TONs of APIs and gems and built a system on AWS that handles 1,000 rpm.
Mysql has been the data store for my apps for years. I've recently switched to postgres, but have years of experience in mysql with php and rails.
I've written whole db management tools in php for mysql, and have a simple db class in php that is a super light weight version of activerecord.
I have built our our hosting on EC2 using rubber.
I have used S3 from php and ruby for a few years for asset storage.
We use cloudfront at Affinity integrated into rails asset pipeline and layering over s3.
