I build metadata ingestion and backend systems that make data easier to discover, govern, and trust.

Data sources → secure ingestion → metadata & lineage → quality & trust

Selected public contributions. Each link goes to the merged pull request behind the work.

Added AWS RDS IAM authentication for MySQL and PostgreSQL metadata ingestion. The change crossed Python connection handling, schema, Java service conversion, tests, and connector docs. I also work with Okta, Google OAuth, Keycloak, and SSO integrations.

Added manifest support and profiling improvements for data lake ingestion, including S3, GCS, and ADLS readers. Extended data quality and profiling for Databricks Unity Catalog and improved BigQuery project discovery, credentials, and nested metadata handling. Snowflake is another platform I know in depth.

Contributed ingestion connectors for Tableau, Metabase, and Power BI, plus Tableau lineage. My metadata work also spans Airflow, Fivetran pipelines, OpenSearch Dashboards, Kafka bootstrap servers, and Schema Registry.

Added validation and a conservative migration for ingestion pipeline configurations across Java and Python. Improved SQL query safety with parameterized construction and regression coverage. Extended the Python SDK's data contract methods.

Built out the public OpenMetadata demo catalog, updated Python SDK documentation, clarified Context Center MCP documentation, and improved a release branch GitHub Actions workflow. I've also contributed extensively to Collate documentation.

The heatmap shows days with contributions on my publicly visible GitHub calendar. The PR count above separately covers authored PRs merged in public open-metadata repositories. Both cards come from the refresh script and scheduled workflow.

I investigate production issues, run root cause analysis, and ship fixes. I coordinate four support teammates and one documentation teammate, and have contributed heavily to OpenMetadata documentation and Collate documentation. I work with Claude Code and Codex alongside VS Code and IntelliJ IDEA.
