Source code recovery
Lost the source? I reconstruct readable, maintainable code from compiled binaries.
SpecterDC
Your code has a future.
Source code recovery, COBOL conversion and legacy modernization. The original developers are gone and the documentation never existed, but the code still runs the business. I bring it into the present, with or without the source.

S
It works. Nobody knows how.
Decades of business logic, written in a language nobody on staff reads, by people who left years ago. Replacing it from scratch risks everything it quietly gets right.
You don’t need to start over. You need a bridge.
Inside SpecterDC
COBOL conversion
COBOL to Java, C#, Python and more, with the business logic intact.
Modernization
Not just translation: restructured, documented and given modern APIs, with the same behavior.
Binary analysis
Understand what a program does without its source: documented functions, mapped logic, flagged vulnerabilities.
Code rescue
Corrupted files, incomplete backups and half-finished migrations, pieced back together.
How an engagement runs.
Discovery
Source, binaries, documentation or just a running system. I scope what you have and the best approach.
Analysis
Business logic, data flows and dependencies, mapped. You get a complete picture of what the system does.
Translation
Converted to your target language with structure improved and behavior preserved.
Validation
Side-by-side comparison and regression tests prove the new code behaves like the old.
Delivery
Clean, documented code and a handover so your team can carry it forward.
