Our applications run on Ruby on Rails. We use Postgres, Elasticsearch, and Cassandra as our datastores. Memcached and Redis for caching. Kinesis for stream processing. Sidekiq for job processing. As we grow to serve more customers and deepen our relationships with our retail partners we are constantly given new opportunities to solve fascinating and rewarding challenges.
