Over five months, Tom Ferns engineered robust notification and web services across repositories such as companieshouse/chs-notification-kafka-consumer and companieshouse/psc-extensions-web. He modernized Kafka-driven pipelines by decoupling message acknowledgment from API integration, improving reliability and testability using Java, Spring Boot, and WebFlux. Tom introduced type-safe interfaces and refactored data handling in TypeScript-based web apps, enhancing maintainability and reducing runtime errors. He also delivered multi-provider email integration with MongoDB-backed APIs, standardized datetime serialization, and implemented mock clients for safer local testing. His work demonstrated depth in backend development, integration testing, and code organization, resulting in scalable, maintainable, and production-ready systems.

March 2025 focused on reliability and maintainability for the Kafka-driven notification pipeline in companieshouse/chs-notification-kafka-consumer, and on modernizing API integration with WebClient. Delivered two core features, improved failure handling, and expanded testability to reduce regression risk and enable faster future work. The changes decouple Kafka orchestration from the API integration layer, ensure message acknowledgments occur only after successful API calls, and simplify integration code, all of which contribute to stronger service-level reliability and business value.
