Transform Legacy Code Into Modern Applications

For small and growing businesses stuck on legacy platforms—CodeShift AI uses supervised AI agents to modernize your outdated software into secure, maintainable, and future-proof systems—without the meetings, manuals, or months of traditional consulting.

Is Legacy Code Holding Your Business Back?

Dying Technology

Your critical application runs on outdated platforms—WinForms, Visual Basic, Java legacy systems—where developers are scarce and expensive.

Lost Knowledge

The original developers have moved on, and there's little to no documentation. Your team is afraid to touch the code.

Platform Limitations

Locked into Windows-only desktop apps when you need web and mobile accessibility for modern business workflows.

Security Risks

Running unsupported software versions with known vulnerabilities, putting your business data and compliance at risk.

Time & Cost

Traditional rewrite projects take 12-18 months and cost hundreds of thousands. You need a faster, more affordable solution.

Business Stagnation

Unable to add new features or integrate with modern systems. Your software has become a competitive liability.

How CodeShift AI Works

Our supervised AI agent methodology delivers professional-grade modernization in a fraction of the time and cost of traditional approaches.

01

Discovery & Analysis

You provide your source code—that's it. Our AI agents perform deep code archaeology, analyzing architecture, business logic, and dependencies without requiring documentation or lengthy meetings.

No documentation needed Automated code analysis Business logic extraction
02

Expert-Supervised Transformation

AI agents handle the heavy lifting, but expert engineers supervise every transformation. This ensures production-quality code, security, and maintainability—not AI-generated slop.

SUCCESS STORY

From Desktop-Only to Cross-Platform: A Real-World Modernization

Transforming a 15+ year old Windows desktop business application into a modern Progressive Web App

The Challenge

A business was running their entire operation on a Windows-only WinForms C# desktop application. The system was critical to operations but faced major limitations:

  • Locked to desktop Windows machines only
  • No mobile or tablet access for field staff
  • Difficult to maintain with aging .NET Framework codebase
  • Limited ability to add modern features
  • Required expensive on-premise infrastructure

The Solution

CodeShift AI transformed the legacy application into a modern Progressive Web App with:

  • Cross-platform accessibility (desktop, mobile, tablet)
  • Modern React + TypeScript architecture
  • Professional UI Reimagined
  • Cloud-ready infrastructure
  • Enhanced security and authentication
  • Real-time synchronization across devices
