Outcomes, not activities.

We lead with what changed for the business — the deadline met, the fine avoided, the system that finally went live. The hours we billed are an implementation detail.

— The challenge

A real-time payments rollout had stalled at the integration layer. The original SI had burned six months on architecture without moving a single transaction. The bank had a regulator-visible commitment date and 80 days to hit it.

— What we actually did
  • 01.Replaced the multi-vendor design with a single ISO 20022 adapter pattern owned end-to-end
  • 02.Embedded four GSG payments engineers inside the bank's release train
  • 03.Rebuilt the test harness against production-shaped data within two weeks
  • 04.Took weekly outcomes reviews directly to the sponsoring EVP, not the steerco

— The challenge

A $40B AUM RIA was losing 22% of HNW prospects between handshake and first-funded account. Average onboarding cycle had crept to 31 days and three of the top five complaints to the CCO referenced the experience.

— What we actually did
  • 01.Mapped every touch — 47 handoffs, 19 systems, 9 unique status emails
  • 02.Killed 11 hand-offs in week one by reassigning ownership inside ops
  • 03.Stood up a single advisor desktop view of the onboarding queue
  • 04.Tied the new cycle time to the advisor compensation dashboard

— The challenge

147 findings across loss-mitigation, billing-dispute handling, and Reg E. The bank's internal program was tracking to miss the regulator deadline by a quarter, with personal liability attaching to two named executives.

— What we actually did
  • 01.Stood up a single intake for findings, evidence, and remediation owners
  • 02.Re-papered the dispute and adverse-action templates against the consent decree language
  • 03.Built a CCO-level dashboard tying every finding to its evidence ID and closure attestation
  • 04.Embedded two former OCC examiners on the daily standup

— The challenge

A multi-year core conversion had two failed cutover rehearsals and an unmoved IT exec sponsoring against. The bank needed a delivery partner who could own the weekend, not the methodology.

— What we actually did
  • 01.Rebuilt the cutover runbook around 38 reversible decision gates
  • 02.Ran four shadow cutovers against production traffic over a 60-day window
  • 03.Negotiated regulator pre-clearance on the rollback protocol in writing
  • 04.Took the bridge on the actual conversion weekend with three GSG MDs in the room

— The challenge

Two prior consultancies had delivered governance frameworks the bank could not actually operate. The third attempt had to produce attestable lineage across 41 risk reports — not slides about lineage.

— What we actually did
  • 01.Replaced the framework-first approach with report-first: started from the 41 reports and worked backward to source systems
  • 02.Stood up an operational data-quality squad of seven, embedded in the CDO function
  • 03.Codified critical-data-element definitions inside the same tool the BU used for ad-hoc reporting
  • 04.Walked auditors through three end-to-end lineage paths in week 30

— The challenge

A high-growth stablecoin operator was running on a Money Transmitter mosaic across 38 states and needed a unified path to a BitLicense plus a federal trust charter — without losing product velocity.

— What we actually did
  • 01.Wrote the regulatory operating model from scratch: BSA officer, compliance committee, board reporting
  • 02.Sat the application with two former NYDFS examiners on the GSG side
  • 03.Ran a parallel federal trust track with separate counsel; kept both regulators informed weekly
  • 04.Embedded a sustained-readiness lead post-license to convert the work into an in-house function
