The VB6 Trap.
A legacy VB6 system choking operations for 9,200+ employees across Northern Europe.
Eltel Networks designs and maintains telecommunications and electrical grids across Northern Europe. Yet, their own Norwegian branch was bottlenecked by a legacy VB 6 order-handling application. The system suffered from critical performance and usability issues, making it nearly impossible to maintain. They needed a rescue mission to migrate their entire operational flow to a stable, modern platform.
Critical Performance Issues
The legacy VB 6 system was reaching end-of-life with severe performance bottlenecks affecting daily operations.
Lost Business Logic
Decades of undocumented code made it nearly impossible to understand core business requirements without deep reverse-engineering.
Operational Friction
Managers and technicians struggled with a system that couldn't keep pace with modern workflow demands.
The Boutique Difference.
Three senior engineers, zero layers of management — direct accountability from architecture to deployment.
Reverse-Engineering the Truth
The most complex challenge wasn't just writing new code; it was uncovering lost business logic. Our senior team successfully restored core business requirements by meticulously reverse-engineering the undocumented legacy code.
Foundational Excellence
As one of our earliest enterprise partnerships, this project set our permanent standard: deeply integrating with the client's off-site managerial and technical teams across different time zones to ensure total alignment.
Complex Ecosystem Integration
We didn't just rebuild the app; we seamlessly connected the new core web applications with Eltel's in-house systems and their external partners' ERPs.
The same founders who designed this engagement still lead every Roxosoft project today.
Modern Web Ecosystem on .NET.
A complete platform replacement — from legacy VB6 to a modern, integrated .NET web ecosystem.
