Cross-Platform Mobile Platform

Problem

Needed a foundation for a cross-platform product with reliable backend and automated deployment. Typical approaches led to fragmented architecture.

Solution

Implemented Clean Architecture with Feature-based structure in Flutter. Backend - serverless on AWS (Lambda in Golang). Infrastructure defined in CDK and deploys automatically.

Technical Details

• Clean Architecture + feature-based modules, event-driven reactive layout, Riverpod for state
• Serverless backend on AWS — Lambda in Go, DynamoDB with composite keys, S3 for media, Amplify and Cognito for auth
• Infrastructure as Code (AWS CDK)

Results

• Architectural and infrastructure foundation implemented
• Fully automated deployment
• Modular structure simplifies further development
• Backend in production-ready state

Lessons Learned

• Clean Architecture pays off on large projects
• Infrastructure as Code is critical for reproducibility
• Serverless reduces operational overhead
