PROFILE
Hyunuk Lim
Hyunuk contributed to the GoogleCloudPlatform/devrel-demos repository by building and refining data governance and analytics features over six months. He developed metadata-driven asset discovery and recommendation workflows, integrating Dataplex metadata with generative AI agents to automate and enforce data governance policies. Using Python, SQL, and Google Cloud Platform services, Hyunuk implemented programmatic data quality checks, materialized views for GA4 analytics, and dynamic governance agents that respect project and region constraints. His work included comprehensive documentation, code cleanup, and prompt engineering to improve governance accuracy, resulting in reproducible, maintainable workflows that streamline onboarding and reduce manual effort in data management.

Jan 1, 2026January 2026 — GoogleCloudPlatform/devrel-demos: Delivered Dynamic Metadata-driven Data Asset Discovery and Recommendation, enhancing data governance with metadata-aware asset discovery and user-query-driven recommendations while enforcing project and region constraints. The work established a structured metadata discovery and search execution flow, enabling more accurate, governance-compliant data asset recommendations and reducing manual discovery effort. A dependency fix (unrestrict ADK version) was applied to stabilise builds and broaden compatibility.

Nov 1, 2025November 2025 — Focused on building a scalable data governance foundation by integrating Dataplex metadata with Generative AI agents and tightening data handling scope. Delivered a foundational governance agent infrastructure, progressed agent/MCP integration to a working state, and enhanced prompt constraints to bolster governance safety. Fixed a critical data governance bug to ensure GEMINI processes only assets from the active project, removing cross-project data handling. These efforts increase governance accuracy, reduce risk, and establish a repeatable, business-value-driven AI data governance workflow for the DevRel demos project.
