Robert D’Almeida contributed to the Adyen/adyen-ios repository by engineering robust 3D Secure 2 authentication flows and enhancing the mobile payment experience. He refactored core components using protocol-oriented programming in Swift, introducing modular abstractions for 3DS2 integration and improving testability. Robert implemented dynamic configuration parsing from fingerprint tokens, centralized service lifecycle management, and delivered cancellation-safe challenge handling to reduce user friction. His work also included UI refinements, localization updates, and feature flagging for authentication flow control, supporting internationalization and faster QA cycles. Throughout, he demonstrated depth in iOS development, API integration, and unit testing, resulting in more reliable, maintainable code.

June 2025: Focused on hardening the iOS 3DS2 flow in Adyen/adyen-ios, delivering a cancellation-safe path for 3DS2 challenges and improving test coverage to ensure no unintended registrations after cancellation. This work reduces user friction and strengthens delegated authentication state handling, contributing to a smoother checkout experience and higher conversion.

April 2025: Delivered the Card Authentication Flow Control feature in Adyen/adyen-ios Demo App, adding an option to force RedirectAction to switch between native 3DS and card redirect flows for testing and validation. This enables faster QA cycles and broader validation of authentication paths. Change tracked in DSP-2075: fe103eaaf6e014ed7ff215c966e9a976ce643178.

February 2025: Key architectural refactor of 3DS2 integration in Adyen iOS SDK. Introduced ThreeDSServiceable protocol to replace ADYServiceAdapter’s concrete dependencies, added new error types and service parameters for fingerprinting and challenge flows. This modularization reduces coupling, improves testability, and accelerates future integrations with different 3DS SDKs.

Month 2024-11 — Adyen iOS work focused on UI polish, authentication resilience, and localization. Key outcomes include a polished Delegated Authentication UI with iPad-friendly presentation, a more robust authentication flow via SDK upgrade and secure-checkout reset, and broader multilingual support through updated translations and 3D Secure messaging. These changes improve user experience, reduce friction in payment flows, and enable faster onboarding for international users.
