Worked on the svix/svix-webhooks repository to enhance API throttling by introducing a new throttleRate property, replacing the deprecated rateLimit across all relevant endpoints. This change improved message throttling capabilities for applications and endpoints, supporting better reliability under high-traffic conditions. The developer implemented a comprehensive deprecation pathway to minimize customer impact and encourage smooth migration to the new property. All changes were delivered with clear documentation and maintainability in mind, ensuring testability and alignment across module endpoints. The work was completed within a single month, utilizing Rust for backend and API development, and focused on delivering measurable business value through improved design.
