PROFILE
Miguel Herran
Over seven months, contributed to the RIPE-NCC/whois repository by delivering 18 features and resolving critical bugs, focusing on backend development, security, and data privacy. Work included migrating configuration from XML to Java-based Spring, enhancing authentication with OIDC and API key validation, and improving data obfuscation for privacy in test environments. Implemented robust API development and integration, optimized Elasticsearch full-text search, and strengthened CI/CD pipelines with integration and unit testing. Leveraged Java, YAML, and Groovy to refactor legacy components, streamline deployment, and improve maintainability. Efforts resulted in more secure, modular, and reliable systems supporting internationalization and cross-RIR interoperability.

Feb 1, 2026February 2026 — RIPE-NCC/whois: Security hardening and data-import reliability upgrades. Delivered an Authentication System Overhaul with a secure path forward (password deprecation, control flag to disable password auth, updated tests and error messaging, plus user guidance toward PGP signing or API keys). Implemented GRS Import Process Enhancements (better timestamp handling and warnings for outdated downloads) to improve data freshness and import reliability. Both initiatives reduce security risk, improve user experience, and bolster data integrity.
