Our SAAS product is a Ruby on Rails application serving a React Single Page Application. This is where we anticipate you'll be working most of the time.

We also leverage Ruby (without Rails) in our scrapers and crawlers to fetch all the data used to power our tool. Those get their tasks from SQS queues and store data in a mix of MySQL, Redshift, MongoDB, PgSQL, and Elasticsearch databases.  You'll have a chance to see all of that into action.

We expose these data in JSON REST API's are built in Ruby as well using the Sinatra lightweight framework. We deploy code using Concourse as a CI/CD pipeline to build Docker images deployed on a Kubernetes cluster hosted on AWS.

We monitor everything using Prometheus and Grafana to visualize time series and metrics in an efficient manner.

We follow an agile development process inspired by SCRUM, but adapted to our needs.
