Vishal worked on the UKHO/s-100-permit-service repository, focusing on enhancing the Permit Service’s error handling mechanisms. He refactored backend C# code to standardize failure responses when the service communicates with the Product Key Service, introducing a result-pattern approach for clearer and more consistent error messaging. By isolating error handling logic, Vishal improved the maintainability and reliability of the API, ensuring downstream consumers receive uniform and actionable error payloads. His work centered on API development, backend development, and robust error handling, addressing the need for predictable service behavior and contributing to a more resilient and maintainable codebase over the month.
