Enterprise Modernization
From exiting mainframes to redeveloping critical applications, I guide organizations through multi-year modernization strategies that reduce technical debt, improve agility, and align technology with business goals.
What You Get When You Engage Me for Modernization
Application Redevelopment & Refactoring
Rewriting or re-architecting apps to modern, maintainable platforms.
Mainframe Exit Strategy
Phasing out mainframes, replacing with modern tech or cloud-native systems.
Application Facelifts
UI/UX and front-end modernization when full rewrites aren’t feasible.
Application Topology & Dependency Diagrams
Wall-sized architectural views of your systems and data flows.
Cloud Migration & Hybrid Cloud Strategy
Planning and executing safe transitions to cloud environments.
Data & Database Integration
Consolidation, integration, and modernizing of your data store architecture.
Key Modernization Challenges I Address
- Outdated, brittle systems that slow down innovation
- Dependence on legacy languages and platforms that limit scalability
- Complexity in application topology, with unclear dependencies
- High operating costs and risk associated with mainframes or legacy stack
- Difficulty integrating new tech (cloud, microservices, APIs) into existing systems
