PROFILE
Herdis Maria
Worked on the island-is/island.is repository, delivering end-to-end payment solutions with a focus on Apple Pay integration, secure e-commerce workflows, and robust backend infrastructure. Leveraged TypeScript, Node.js, and Kubernetes to implement domain verification, cryptographic signature validation, and catalog-driven payment method selection. Enhanced reliability through modular refund processing, soft delete safeguards, and improved logging and error handling. Introduced OpenAPI client generation for health service integration and standardized authentication contexts. Strengthened security compliance by enforcing strict certificate checks and PCI log scrubbing. Prioritized maintainability with code refactoring, environment-aware configuration, and comprehensive test coverage, supporting scalable, production-ready payment and authentication systems.

Mar 1, 2026March 2026 payments domain highlights for island.is. Delivered catalog-driven payment method integration with environment-aware toggles to enable flexible, catalog-based checkout across environments, including Apple Pay configuration controls. Implemented a robust fallback to CARD when no valid payment methods are available, increasing payment reliability in edge cases. Launched a dedicated refund module with improved logging and modular refund workflow, and enhanced the invoice refund saga for maintainability. Introduced soft delete for payment flows and FJS charges with data integrity safeguards and a new unique constraint to prevent duplicates. Enhanced payment processing reliability and observability through better worker logging, standardized error handling, and reduced exposure of non-actionable errors. Collectively, these changes improve payment success rates, reduce support toil, and enable safer, more maintainable refund and data-handling workflows.

Oct 1, 2025October 2025 monthly summary focused on delivering a Health Directorate Health Service OpenAPI client and improving integration reliability. Key outcomes include generation and adoption of OpenAPI clients and types via openapi-ts (v2), refactoring existing services to consume the generated clients, hardening data mappings to handle potential null values, and introducing an authentication context to standardize request handling. This work reduces API client maintenance, improves reliability, and enables smoother backend integration.
