About the Tech
Technology and our people is what makes Tide possible. We work in autonomous teams where backend, iOS, Android, web, QA, DevOps, agile coaches, data experts and product owners solve difficult problems together to get the job done. We self-organise and discuss technical challenges and set our own guidelines in the different Community of Practices.
On the backend we see Java 8 as legacy and use Java 11+ for our micro-services. We provide RESTful APIs to our colleagues in the frontend, but also use gRPC for internal service-to-service communications. Spring Boot is our work horse, but we are open to new experiments. We are cloud-native and run everything on AWS. You’ll see containers (Docker), queues (SNS+SQS) and events everywhere. The nature of our business naturally fits with relational databases, but we have also found some use cases for NoSQL.
Our frontends have done an incredible job at consuming our APIs and providing the best UX to our members. They are fully native Android and iOS apps or Angular 2+ web apps. DevOps provides vital infrastructure and operations support.
