PROFILE
Ben Norcombe
Ben Norcombe contributed backend features to the letsencrypt/boulder repository, focusing on operational simplicity and system resilience. He implemented profile-driven issuer activity by deprecating a legacy configuration field, allowing issuer behavior to be managed through profiles for clearer, more flexible signing logic. Using Go and gRPC, Ben also removed a feature flag to make the renewal information endpoint always available, streamlining maintenance. He introduced jitter to ARI Retry-After headers, improving load distribution during retries, and refactored gRPC error handling for clarity. His work demonstrated depth in API development and backend engineering, emphasizing maintainability, reliability, and developer productivity throughout the codebase.

Jan 1, 2026January 2026 highlights for letsencrypt/boulder: - Implemented profile-driven Issuer activity by deprecating IssuerConfig.Active and enabling issuer activity to be determined by Profiles, reducing configuration drift and enabling per-profile signing behavior. - Removed the ServeRenewalInfo feature flag, making the renewal information endpoint always available and simplifying usage and maintenance. - Introduced a jitter of +/-20% for the ARI Retry-After header to improve load distribution during retries and reduce thundering herd effects. - Refactored gRPC error handling by simplifying ProblemDetailsToPB to remove the unused error return, improving usability and clarity in error handling. Impact and business value: - Operational simplicity: fewer feature flags and deprecated fields reduce configuration complexity and maintenance burden. - Reliability and scalability: jittered retries and stable renewal info endpoint improve system resilience under load. - Developer productivity: cleaner error handling and clearer configuration pathways shorten debugging and integration cycles. Key commits: - 0c321f7e6eaf76c6a975b752254bca6af176c695 (Issuer Configuration by Profiles) - 1afad15bae22a2e4fd55a2b0eb6712cacfb5dda8 (Always-on Renewal Information Endpoint) - 02abf8dc68176120574d327ced56b50447f4a9da (ARI Retry-After Jitter) - 0bc6a5856338847a7f2a6f2763cc374e9c00b0df (Simplify ProblemDetailsToPB)
