Application Redevelopment & Refactoring
Rewriting or re-architecting apps to modern, maintainable platforms.

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- Outdated, brittle systems that slow down innovation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
