Data Analyst · Automation & Data Pipelines
I design and build data pipelines that automate collection, processing, and analysis — not just dashboards, but reproducible systems that generate reliable data over time.
Python SQL Data Automation CI/CD ETL
"Data is not just analyzed. It must be generated, structured and sustained."
- Automated data pipelines (scraping + storage + CI/CD)
- Data analysis with Python & SQL
- Transitioning towards Data Engineering
- Collection — Playwright, yt-dlp, Selenium, REST APIs
- Processing — Python (Pandas, NumPy), SQL (CTEs, window functions)
- Orchestration — GitHub Actions
- Visualization — Power BI, Streamlit
End-to-end ETL pipeline that downloads, enriches, and analyzes YouTube weekly charts. Features multi-source artist enrichment (MusicBrainz, Wikipedia, Wikidata, DeepSeek), 3-layer metadata retrieval (API / Selenium / yt-dlp), and automated bilingual Jupyter notebooks with AI insights.
