We have a modern tech stack built with microservices architecture on AWS. In terms of programming languages, we use Golang where we need high concurrency, Erlang when we need distributed computing, Ruby on Rails for APIs/dashboard and business logic, Python for our machine learning pipelines. We use multiple databases including Cassandra/ScyllaDB, REDIS, ElasticSearch, Hbase, Druid, S3, Postgres and more, we optimize for “data usage” versus “data storage”. Massive data scale (nearly a petabyte of data).
