Flip is a vertically integrated social commerce platform delivering a revolutionary shopping experience in the US. The platform has been developed at a great scale with a service-oriented architecture. We’ve created a code ecosystem with over 150 auto-scalable microservices behind the API gateway integrated with a unified logging layer and common monitoring. Those homogeneous Node.js microservices rely on the Nest framework. Such an approach allows us to build a microservice that is production-ready in 15 minutes. What is more, we use HA/HPA systems which are scalable depending on the user traffic. When it comes to databases, our go-to solutions are MongoDB, Scylla, and SQL.
