• Design payment solutions that meet business, regulatory, security, resiliency, scalability, performance, availability and operational requirements across domestic, cross-border, real-time and high-value payment flows.
• Drive payment modernization and migration initiatives, including current-state assessment, target architecture definition, domain decomposition, coexistence design, migration roadmap, cutover strategy, data conversion and rollback planning.

• Effective collaborator with the ability to influence stakeholders, manage trade-offs and drive consensus across business, architecture, engineering, infrastructure, security and operations teams.
