PROFILE
Chien-chi Liu
Over a three-month period, contributed to the Prof-Drake-UMD/INST767-Sp25 repository by architecting and implementing a cloud-native data integration and analytics platform for job market data. Established project scaffolding and comprehensive documentation to streamline onboarding and future development. Developed a unified ETL pipeline in Python to standardize and ingest postings from multiple APIs, including Adzuna, Jooble, and Muse, into a single JSON schema. Leveraged Google Cloud Platform services such as Pub/Sub, Cloud Functions, and BigQuery to enable scalable, event-driven data processing and analytics. Enhanced data modeling, standardized schemas, and improved SQL queries to support reliable, maintainable, and extensible analytics workflows.

May 1, 2025In May 2025, delivered a cloud-native data integration and analytics foundation for job market data in the Prof-Drake-UMD/INST767-Sp25 project. Implemented a unified ETL to ingest and standardize postings from Adzuna, Jooble, and Muse into a single JSON, grouped API connection files under a new directory, and updated the data schema with a new category field. Established a comprehensive data model foundation for job data, including definitions for various job descriptions and details, and produced an end-to-end prototype with CSV export, supported by BigTable and SQL query capabilities. Modernized ingestion/transformation pipeline with Pub/Sub and Cloud Functions to ingest data into Cloud Storage and trigger transformations, enabling scalable, event-driven processing. Fixed BigQuery SQL queries and table definitions, updated documentation, and improved data analysis capabilities to support reliable analytics. Overall, these efforts create a scalable, maintainable data platform, reduce data variance, accelerate analytics, and enable data-driven decisions across the business.

Apr 1, 2025Month: 2025-04 Key features delivered: - Job Market Data Pipeline Documentation and API Integrations: Delivered a comprehensive README documenting the pipeline architecture, data sources, components, unified schema, update schedule, API layer, and technologies. Introduced new Python modules for integrating with Adzuna, Jooble, and Muse APIs, including API requests, data extraction, and error handling, with example usage. - Architecture/tech adjustments: README updated to reflect Jooble data source and related architectural/tech adjustments. Major bugs fixed: - No significant bugs fixed this month. Overall impact and accomplishments: - Strengthened maintainability and onboarding for the Job Market Data Pipeline, enabling faster integration of additional data sources (e.g., Jooble) and clearer governance of the data flow. This work lays the foundation for more timely and comprehensive job-market data delivery to stakeholders. Technologies/skills demonstrated: - Python development for API integrations; API design and error handling; robust data extraction; documentation best practices; cross-source data integration; Git version control.
