Legacy Code Modernization
Give new life to old systems. We migrate COBOL, FORTRAN and legacy applications to modern technologies.
Legacy Code Modernization
COBOL Migration
Transformation of mainframe systems to Java, .NET or modern microservices.
FORTRAN to Python
Modernization of scientific code preserving critical business logic.
Legacy Maintenance
Support and incremental improvements on systems that can't be migrated yet.
Integration APIs
We expose legacy functionality as modern APIs for new applications.
Reverse Documentation
We document undocumented systems to facilitate future migrations.
Legacy Testing
We create test suites for code without coverage before modifying.
How we work to guarantee your project's success
Code Archaeology
Deep system analysis: dependencies, flows, hidden business logic.
Migration Strategy
We define approach: strangler fig, big bang, or hybrid based on risk.
Abstraction Layer
We create interfaces that allow coexistence of legacy and new code.
Incremental Migration
We move functionality module by module with continuous validation.
Decommission
We retire legacy system only when new system is 100% validated.
Specialized tech stack for this service
Real scenarios where we apply this solution
The Problem
Bank with 30-year-old COBOL core banking, impossible to hire maintainers.
Our Solution
Progressive migration to Java microservices with strangler fig pattern.
The Result
50% of system migrated in 18 months, new features 10x faster.
The Problem
Manufacturing company with FORTRAN system for engineering calculations.
Our Solution
Rewrite in Python with NumPy preserving numerical precision and exhaustive validation.
The Result
Maintainable code, integration with modern tools, 5x faster.
