Transformation Experience

Relevance and judgment, not a résumé

Each engagement is presented as a case study — challenge, approach, outcome, and impact — to show how John brings clarity to complex, high-stakes situations.

Platform Strategy

Global Calypso Rationalization Strategy

Challenge
Fragmented Calypso footprint spanning business lines, operating models, versions, geographies, and user groups, with no unified path forward.
Approach
Architecture assessment, operating-model review, future-state planning, release model, codebase strategy, and transformation planning.
Outcome
A consolidated target-state and a sequenced roadmap that aligned stakeholders around a single, defensible direction.
Impact
Reduced platform fragmentation and a clearer, lower-risk modernization path.

Market Transition

LIBOR-to-SOFR Impact Modeling

Challenge
A benchmark transition with wide, uncertain downstream impact across products, curves, and processing.
Approach
Structured impact modeling across instruments, workflows, and reporting to surface hidden dependencies.
Outcome
A prioritized impact map that turned ambiguity into an executable workplan.
Impact
Clear remediation scope and reduced transition risk.

Operating Model

Treasury Settlement Optimization

Challenge
Settlement processes that introduced friction, exceptions, and operational risk.
Approach
Workflow analysis, exception modeling, and targeted process and configuration redesign.
Outcome
A streamlined settlement model with fewer manual touchpoints.
Impact
Lower operational risk and improved straight-through processing.

Architecture

Global Collateral Architecture

Challenge
A large institutional collateral environment required stronger architecture and process design.
Approach
Functional design, workflow modeling, data-use assessment, and implementation support.
Outcome
A structured collateral operating model and a clearer system-of-record approach.
Impact
Improved data integrity and a more scalable collateral foundation.

Quality & Readiness

Risk-Based Testing Framework

Challenge
Testing effort spread thin without a clear link to actual delivery risk.
Approach
A risk-based testing framework prioritizing coverage where impact and uncertainty were highest.
Outcome
Focused test execution and more credible release-readiness decisions.
Impact
Higher confidence at go-live with better-targeted effort.

Product Leadership

Trading Platform Product Management

Challenge
A platform initiative lacking clear product direction and requirements ownership.
Approach
Product management discipline connecting business intent, requirements, and delivery.
Outcome
A coherent backlog and aligned stakeholders across business and technology.
Impact
Faster decisions and reduced rework.

Delivery

Program Recovery

Challenge
A high-stakes program drifting on scope, governance, and stakeholder alignment.
Approach
Independent assessment, re-baselining, and a restored governance and delivery cadence.
Outcome
A stabilized program with a credible path to completion.
Impact
Recovered momentum and renewed sponsor confidence.

Transformation

Platform Modernization

Challenge
A modernization effort with significant but poorly understood downstream impacts.
Approach
Architecture-led planning that mapped dependencies and sequenced change safely.

A modernization plan that protected downstream processing.
Impact
Reduced surprises and a smoother transition.
