PROFILE

Zelin Hao

Jerry Hao focused on enhancing CI/CD credential management and Maven snapshot publishing workflows across several OpenSearch repositories, including k-NN, anomaly-detection, security-analytics, neural-search, and skills. He migrated credential storage from AWS Secrets Manager to 1Password secrets integration, automating secure credential delivery within Gradle and Groovy-based pipelines. By updating repository endpoints to Sonatype Central and standardizing secrets management, Jerry reduced operational risk and improved release reliability. His work established cross-repo consistency, streamlined artifact publishing, and strengthened security posture. Over two months, Jerry delivered five features without reported bugs, demonstrating depth in CI/CD, DevOps automation, Maven publishing, and secrets management.

June 2025 performance summary for OpenSearch projects (k-NN and anomaly-detection). Key features delivered focus on CI/CD credential management and centralized Maven snapshot publishing to improve security, consistency, and release reliability. In opensearch-project/k-NN, migrated CI/CD credential loading from AWS Secrets Manager to 1Password secrets loading action and updated the Maven snapshot publishing endpoint to the central Sonatype repository (commit ae6a67a60661cecef2d36ec09ddef97eaeba31ac). In opensearch-project/anomaly-detection, implemented secure Maven snapshot publishing via 1Password integration, replacing AWS Secrets Manager with 1Password secrets action and updating the snapshot publishing URL to central Sonatype endpoint (commit d92bb7e34f93c400989386a119373458f76596f8). No major bugs reported this period. Overall impact: strengthened security, reduced credential surface area, and standardized publishing workflows across both repos, enabling faster, more compliant releases. Technologies/skills demonstrated: secrets management automation (1Password), CI/CD pipeline hardening, Maven snapshot publishing, cross-repo standardization, and integration with central Sonatype repository.
