Project Overview
The Wallet Migration System is a secure, end-to-end platform designed to migrate user wallets and balances between legacy systems and new platforms. It ensures data integrity, transaction history preservation, and seamless user transition without service downtime.
Key Features
- User Wallet Syncing
Maps user accounts and wallet IDs between platforms for accurate migration. - Real-Time Transaction Validation
Ensures all balances and transaction logs are verified before transfer. - Rollback & Audit Logs
In case of failed transfers, the system allows for rollback and detailed audit trails. - Multi-Currency Support
Handles wallets with multiple currency balances, applying proper conversion if needed. - Migration Dashboard
Provides real-time progress tracking, status filtering, and admin approval controls. - Security & Encryption
Sensitive data is encrypted and transferred over secured channels using modern protocols.
Tech Stack
- Backend: C# .NET Core
- Database: MySQL
- Queue System: RabbitMQ (for async task handling)
- Monitoring: Grafana + Prometheus
- Deployment: Dockerized microservices
My Role
I was responsible for the entire backend logic and wallet reconciliation process. I designed the database schema, developed APIs, implemented logging/monitoring, and ensured transaction accuracy across millions of records.
Outcome
- Migrated over 1 million user wallets
- Achieved zero downtime during migration
- Improved audit trail transparency and rollback efficiency
