Mastercard - iOS Payments SDKs

During my 5.5 years at Mastercard UK, I led the architecture and development of multiple enterprise-grade iOS Payment SDKs built from the ground up. I was involved across the entire product lifecycle from API design and backend collaboration to SDK architecture, development, documentation, client onboarding, and post-launch support. These SDKs are used by tier-1 banks and global merchants.

  • Designed scalable, modular SDK architecture in Swift
  • Modernized legacy Objective-C SDKs to Swift
  • Migrated static .a libraries to XCFramework distribution
  • Authored SDK documentation and enterprise integration guides
  • Contributed to API specifications and collaborated with Java backend teams
  • Led the mobile team, worked cross-functionally, and supported client integrations end-to-end

Impact: Adopted by leading banks and major merchants, serving thousands of users and processing multi-million-dollar transactions.
