Reconciliation parity
The challenge
Product launches took months because every change risked breaking COBOL-era batch jobs. Hiring developers willing to maintain the system was nearly impossible, and regulators demanded faster change transparency.
What we did
An anti-corruption layer translated between legacy and new domains. Quoting launched first as a standalone service, then claims, then billing — each with dual-run reconciliation proving parity before cutover.
The results
- New product launch time from 5 months to 3 weeks
- Dual-run parity above 99.999% before each cutover
- Legacy licence footprint cut 60%
- Developer hiring funnel doubled in quality candidates
