PROFILE
Raymond Cheng
Raymond Cheng led the development of the opensource-observer/oso platform, delivering a robust data and analytics infrastructure with a modern, scalable frontend. He architected unified data pipelines using Python, SQL, and SQLMesh, integrating sources like BigQuery and Hasura to enable federated analytics and reliable data warehousing. On the frontend, he implemented a component-driven workflow with React, TypeScript, and Plasmic, introducing Storybook-based testing and shadcn/ui integration for maintainable UI development. His work included secure authentication, API usage analytics, and CI/CD hardening, resulting in a maintainable, extensible system that improved onboarding, data quality, and developer productivity across the codebase.

Feb 1, 2025February 2025 – Monthly summary for opensource-observer/oso Key features delivered: - SqlMesh migration and data model consolidation: migrated core data models (e.g., int_events__dependencies and int_events__funding) to SqlMesh, consolidated key event models for a unified data pipeline (including dependencies and funding), adjusted JSON handling, and restructured staging models for compatibility. Expanded coverage to include more staging models moving from dbt to sqlmesh and organizing metric/intermediate models under a dedicated subdir. - External data sources integration with SqlMesh: introduced SqlMesh-based staging models and macros to ingest and standardize data from OSS Directory and Op-Atlas (oss-directory staging models; op-atlas project/artifact source). - CI/docs improvements and deprecation of dbt usage: improved developer experience with updated docs and CI workflows, added Trino debugging tips to the README, disabled dbt runs in test-deploys, and ensured dependency installation steps (e.g., poetry install) for CI jobs. - API/Hasura synchronization and metric model cleanup: aligned Hasura API and metadata with SqlMesh changes, removed obsolete metric fields, and updated export/type mappings for consistency (refreshed Hasura API and adjusted key_metrics/ mart models). - Project structure cleanup and maintenance: renamed/reorganized project structure, removed unused models, and tidied metadata references for clarity and maintainability. Major bugs fixed: - Materialization and staging fixes: resolved issues with materializing open collective staging models and refined staging workflows (#2929). - JSON handling corrections: replaced JSON_VALUE with json_extract_scalar in int_events__funding to fix data extraction (#2931). - Hasura/metadata alignment: fixes around Hasura schema refresh and key metrics model adjustments to ensure API consistency (#3005, #3043, #3039, #3047, #3044). - CI/test-deploy reliability: disabled the dbt run in test-deploy and ensured proper CI steps for dependency installation (#2974, #3038). Overall impact and accomplishments: - Business value: Established a unified, SqlMesh-driven data pipeline pairing core and external data sources, enabling more reliable analytics, faster onboarding, and easier maintenance. - Reliability and consistency: Cleaned and synchronized API/Hasura surfaces with the data model, reducing data drift and improving export/type consistency. - Developer experience: Improved docs, debugging guidance, and CI stability, reducing onboarding time and CI-related friction. - Maintainability: Project structure cleanup and metadata tidying facilitate future development and reduce technical debt. Technologies/skills demonstrated: - SqlMesh migration and data modeling across internal and external data sources - Data quality and JSON handling improvements (json_extract_scalar) - Hasura API synchronization and metric model cleanup - CI/CD enhancements, Trino debugging, and poetry-based dependency management - Codebase maintainability: project structure cleanup, staging model migrations, and macro-based ingestion patterns
