The problem. During a U.S. investment sweeps migration, client master data was missing for roughly 2,000 clients. If the migration had gone ahead, postings would have failed or landed in suspense.

What I did. I raised the gap early, worked out which records were affected, and pulled Product, SAP, Party Central, and Operations into the same discussion so the records could be restored.

Result. The missing records were addressed before they could turn into downstream posting errors.

The problem. Before the legal entity transition, the Madrid and Milan balance sheets carried a large volume of old items. Nobody had a clear view of which ones could be cleaned up and which had restrictions.

What I did. I reviewed about 50,000 items and sorted the 214 cleanup candidates by treatment: reclassification, restricted income attribution, or confirmation needed. I then took the list to the controllers and led the cleanup of 15K+ balance sheet lines.

Result. Controllers received a short, categorized list to act on, and I caught a major mapping error before it posted.

The problem. The post-Brexit EMEA realignment required moving businesses into new entities while keeping ledgers, reference data, and reconciliations intact.

What I did. I delivered the Brussels PU Flip end to end and led the Paris PU Swap from the Financial Control side. For Paris I facilitated the creation of 300+ GL accounts and built the ownership mapping, then supported migration-weekend entries and validation.

Result. Both moves were delivered, and I later led the Madrid and Milan analysis and cleanup.

The problem. On the Brazil cash model, iDDA-to-GL mapping, suspense, and self-balancing accounts were unresolved. Turkey had open GL and accounting schema questions that blocked development.

What I did. I hosted the working sessions, put each open question in front of the person who owned the answer, and documented the UCOA, ownership, reconciliation, and reporting data Finance needed.

Result. Brazil moved forward and earned a peer award. Turkey's account setup could progress once the requirements were written down.

The problem. JPM Coin needed a dependable way to prove that activity on the blockchain matched the books.

What I did. I volunteered to build the Alteryx reconciliation between the blockchain and the ledger. I later built a second one for iDDA Branch 317, where activity was not feeding through GLASS. I also own the wider move of manual processes onto the Alteryx server to close control gaps.

Result. The reconciliation work reduced manual effort and added control checks. Related work automating Liink Billing journal entries produced a documented two-hour time saving.

The problem. The North America liquidity balance sheet depended on product processor flows that needed to run more reliably, and ledger platforms differed across regions.

What I did. As Senior Financial Controller, I optimized straight-through processing in two product processors, worked with the PMO on an SAP re-direct, and built reconciliation models for U.S. Investment Sweeps across North America and EMEA.

Result. Success rate reached 98%, three legacy platforms were retired, and $64M in deposits interest expense was substantiated within six months.
