Tferns-ch

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.
