I am a senior Ruby on Rails developer. I've been working with Rails for 12 years. I also bring several years experience building data warehouses and ETL processes so I also bring that data storage/processing/retrieval performance optimization perspective when building web applications. I'm comfortable working on the front end. I can work with traditional monolith Rails projects, or build UIs using React or Vue. I also have some devops skills and can get you set up with cloud hosting via Heroku, DigitialOcean or AWS (ECS, EC2 auto-scaling groups) and can get your application running on docker for easy developer on-boarding or deployment.
