The Problem
Two previous modernization attempts with other development agencies had failed. The internal team lacked .NET Core expertise and needed a partner who could modernize without disrupting live Fortune 500 operations.
Strategic intervention required
Our Approach
We upgraded the system module by module, running old and new in parallel throughout the migration. Six phases, zero downtime.
Phase 01
Month 1-2Phase 02
Month 3-6Phase 03
Month 7-9Phase 04
Month 10-18Phase 05
Month 19-24Phase 06
Month 24+New Architecture
The new architecture decouples every domain into independently deployable services enabling teams to ship features in days, not months.
Backend
.NET Core 6 (migrated from VB.NET)
Real-time
SignalR WebSockets
Frontend
React with TypeScript
Cloud
AWS (EC2, RDS, S3, CloudWatch)
