Card Systems ConsultingComplex card platform conversions, led by someone who's done it before.
25+ years leading enterprise credit card, payments, and digital banking initiatives for regulated financial institutions — from ground-up platform builds to Fiserv and TSYS conversions, UAT governance, and vendor coordination.
Where clients bring us in
Engagements typically start with a platform conversion, a program that's lost momentum, or a need for hands-on technology leadership. This is where the experience runs deepest.
Card platform conversions & migrations
Planning and leading complex conversions between card processing platforms — including TSYS-to-Fiserv/First Data migrations — coordinating vendors, technology teams, and business stakeholders from strategy through stabilization.
UAT & QA strategy
Building and running UAT and QA governance for card, payments, and lending programs: test strategy, defect triage and resolution, release readiness, and production validation.
Systems integration & vendor management
Coordinating multi-vendor, multi-team integration efforts across core banking, digital banking, and payment rails, including product control file settings, data mapping, and file exchanges.
Digital banking & lending platform delivery
Leading delivery of digital banking and lending platforms — including portal builds and loan origination system integrations — from technical design through launch and stabilization.
Program & technology leadership
Serving as a trusted advisor to executive, business, and technology stakeholders, translating strategy into scalable technology roadmaps and implementation plans.
Risk, compliance & release governance
Ensuring deliverables meet audit, compliance, security, and regulatory requirements, with clear test summaries, release sign-offs, and status reporting to leadership.

Enterprise-tested playbooks
Recommendations are grounded in leading real conversions across TSYS, Fiserv, and First Data inside regulated financial institutions, not theory.
Governance built in
QA, UAT, defect management, and release governance are part of every engagement, built to meet audit, compliance, and regulatory requirements from the start.
A trusted advisor, not just an SME
Works directly with executive, business, and technology stakeholders to keep programs aligned from strategy through stabilization.
One senior consultant, not a bench of juniors
Card Systems Consulting Services is a boutique practice built on 25+ years leading enterprise technology initiatives inside regulated financial institutions — credit card platforms, payment processing, digital banking, lending systems, and large-scale conversions.
That experience spans building a bank's retail and commercial card platform from the ground up, leading six credit card conversions to Fiserv, and serving as a senior leader on a TSYS-to-First Data/Fiserv conversion spanning 31 technology teams. Engagements are kept deliberately few so each client works directly with the person doing the work.
