⛅️ Backend

• We use Google Cloud and leverage managed services as much as possible
• We use Typescript & Node.js for our backend codebase
• We are using a monorepo with Bazel to keep the codebase neatly modularized
• We use Prettier & ESLint to enforce (widely spread) best code style practices
• We use Mocha as test framework, Chai (expect) for assertions and Sinon for spies and mocks
• We use Postgres for relational databases, Firestore for real-time databases
• We use Hapi for REST APIs, generated from OpenAPI specifications
• We use Cloud Build for continuous integration and deployment

📱 Apps

• We use Dart and Flutter to create our mobile app
• We use Bitrise for continuous Integration

🖥 Front-end

• We use React & Next.js
• We use Mocha as test framework, Chai (expect) for assertions and Sinon for spies and mocks

... and we use Github for source code management.
