Ziv Tirosh enhanced the spotinst/openapi repository by developing two features aimed at improving Azure credential management. He introduced a mandatory expirationDate field within the Azure credentials schema, updating both the API and configuration validation to enforce this requirement. To further support governance and reliability, Ziv implemented automated reminders for upcoming credential expirations, reducing the risk of service disruption. He updated the API documentation to reflect these changes, ensuring clarity for future developers. His work demonstrated a strong command of API design, schema definition, and YAML, delivering targeted improvements that addressed both operational reliability and developer experience within a short timeframe.
