Legacy .NET & Windows application modernization
Modernize critical software without losing what already works.
ShamuWare helps companies evaluate aging .NET and Windows applications, reduce operational risk, and create practical modernization roadmaps for cloud, mobile, APIs, and AI.
Architect-led guidance backed by more than 25 years of software engineering and solution architecture experience.
Direct senior involvement
The same senior architect works with you from discovery through roadmap — consistent judgment, start to finish.
25+ years of engineering depth
Principal/Lead engineering and solution-architecture experience across business-critical systems.
Outcomes over headcount
A boutique consultancy focused on architecture and modernization outcomes, not staff augmentation.
Signs it's time to modernize
The application still works. That's part of the problem.
Most legacy .NET and Windows platforms aren't broken — they're just increasingly expensive to change. These are the patterns that usually mean it's time for an honest assessment.
- Releases take too long and carry too much risk.
- Critical knowledge is concentrated in a few people.
- Older .NET Framework dependencies block progress.
- Desktop applications are difficult to extend or deploy.
- Integrations depend on fragile workarounds.
- Cloud discussions never become an executable plan.
- Security and supportability concerns are increasing.
- Mobile, API, data, or AI features are difficult to add.
- A complete rewrite feels too risky and expensive.
The primary engagement
Legacy .NET Modernization Assessment
A focused, fixed-scope engagement that turns "we should modernize this someday" into a prioritized, defensible plan your team can actually execute.
Beyond the assessment
Consulting built around outcomes, not a technology checklist
Four capability areas cover the full path from evaluation to modernized, AI-ready systems.
How modernization actually happens
A pathway, not a leap
Modernization rarely means starting over. Most engagements move a system through deliberate stages — understood, assessed, and re-architected in the parts that matter most.
