Barclays - Reconciliation Platform Migration
Migrated a production reconciliation platform processing 2M daily transactions with zero-disruption cutover.
Overview
Enterprise-scale delivery inside Barclays' reconciliation technology group: moving a live platform that reconciles 2M daily transactions off a licensed vendor system onto the in-house Reclite platform, without a single disrupted business day.
Problem & Insight
- ·The reconciliation platform ran on Intellimatch, an external licensed dependency with rising cost and limited extensibility.
- ·Match accuracy sat at 84%, pushing thousands of breaks per day into manual investigation.
- ·Break ageing averaged 5 days, and release practices differed per module, making incidents frequent and hard to trace.
Solution & Process
- ·Planned and delivered the migration across 3 phased releases, each with a reversible cutover path.
- ·Owned a net-new reconciliation workflow end to end as sole module owner, from rules design to operational handover.
- ·Standardised release runbooks and post-release verification so every module shipped the same way.
Results & Impact
- ✓Match accuracy from 84% to 97%
- ✓External licensing dependency fully eliminated
- ✓Manual effort down 15 hrs/week; break ageing from 5 days to under 24 hours
- ✓Deployment incidents down 40% across 4 modules using the standardised runbooks
