A prepaid financial platform built on distributed microservices, where verification and mobile messaging both had to be reusable across several products instead of reimplemented in each one.
- Challenge
Verification logic and mobile notifications were both needed by multiple parts of the platform, and duplicating either one per service would have multiplied security risk and maintenance cost alike.
- Solution
I designed and implemented two dedicated .NET services, each independently deployable and integrated with the rest of the platform through Dapr. The verification service handled one-time passwords with explicit validation rules, expiry handling, status tracking and production-oriented logging. The notification service delivered push notifications to mobile devices through Azure Notification Hubs.
- Result
The platform gained single, reusable components for verification and for mobile notifications, which other services could adopt without reimplementing either, alongside backend integrations and reliability improvements across MSSQL and Azure.
