Taky Chan developed data engineering and analytics pipelines for the Prof-Drake-UMD/INST767-Sp25 and INST-760-SUMMER25 repositories, focusing on sustainability and content analytics. He designed scalable data models and automated ingestion workflows using Python, SQL, and Apache Airflow, integrating APIs and orchestrating ETL processes on Google Cloud Platform. His work included building end-to-end Airflow DAGs for BigQuery, implementing robust error handling, and enhancing documentation with visual assets and onboarding guides. Taky also delivered interactive dashboards and expanded datasets for analytics and machine learning, demonstrating depth in data curation, transformation, and visualization while ensuring maintainable, business-ready solutions for stakeholders.

Aug 2025: Three feature-driven deliveries in Prof-Drake-UMD/INST-760-SUMMER25 delivering business value through data visualization, presentation assets, and dataset expansion. Iris Data Visualization Suite: Python-based visualization for the Iris dataset (scatter plots) with PNG exports and an interactive dashboard with filters for species, sepal/petal dimensions. Project 3 Visual Asset Pack: five new image assets representing stages (pre-COVID, COVID crash, recovery, growth, post-COVID) for improved docs/presentations. Expanded MSFT Data for Stock Analysis: expanded MSFT.csv to support historical stock analysis and ML model training. Commits: 01f8355a904c62c4edd5f380fb262022cf2405a0, 3e549198cf449425affa3e644a0b8ad80e950ba5, 391d08f6440e80f91fbca9a20df0196b47cb2020, a2608ad3c09e537b32d0ee55a02734acc31a9475. No major bugs fixed this month. Impact: improved data insight, clearer stakeholder communication, and richer analytics assets. Technologies/skills: Python data visualization with pandas/seaborn/matplotlib, interactive dashboard, data curation and dataset expansion, Git-based traceability.
