EF Education First

We're a small startup-like team in a big profitable company, building an iOS/Web app to teach English in public schools. Our app has been live for a couple of years now, teachers love it and we’re expanding across Europe. Our backend stack is AWS-based with lots of python and some golang. We’re building new microservices in golang and deploying them to AWS Lambda + Aurora Serverless. We already have a couple of endpoints deployed using Appsync (GraphQL) and will be trying to use this for new backend/frontend communication. We use Cassandra, DynamoDB, ElasticSearch and PostgreSQL.
