Team & Duration
Core Stack
Our client is a global hardware manufacturer specializing in RFID systems, IP cameras, and enterprise networking equipment. Their products are deployed across Fortune 500 supply chains, including operations for PepsiCo in the United States.
With 150+ employees and operations spanning North America and Europe, the client needed enterprise-grade software to manage device deployments for their corporate customers.

Business Impact
Previous Attempts
Two previous modernization attempts with other development agencies had failed. The internal team lacked .NET Core migration expertise, and they needed a partner who could modernize without disrupting live operations serving Fortune 500 clients.
!Strategic intervention required
We proposed an incremental modernization strategy—upgrading the system module by module while keeping it fully operational for existing clients.

1. Incremental Approach
Migrated module-by-module, never risking the entire system.
2. Zero Downtime
Old and new systems ran in parallel during transition.
3. Deep .NET Expertise
Our team had extensive VB.NET and .NET Core experience.
4. Timezone Alignment
US-aligned hours meant real-time collaboration.
5. Long-term Partnership
We invested in understanding their business, not just their code.
Two other agencies failed this client's modernization. We succeeded. Let's discuss your legacy system and see if we can help.
"This project started with a single discovery call. Three years later, we're still building together. Your project could be next."
