The challenge
A federal civilian agency operated a 30-year-old COBOL mainframe processing benefits for millions of citizens. Vendor support was ending, talent pool was shrinking, and an OIG audit flagged the platform as a continuity-of-operations risk. Modernization had been attempted twice and stalled.
Our approach
- 01Application portfolio analysis and dispositioning across rehost, refactor, and rebuild paths
- 02FedRAMP-aligned AWS GovCloud landing zone with NIST 800-53 control inheritance
- 03Strangler-pattern decomposition of the core benefits engine into modern services
- 04Pair programming with the agency's mainframe team to capture and translate business logic
- 05Parallel-run validation against production transactions for the full release cycle
