Experience

Article Archiving Tool

As a side project, I built an Airflow-orchestrated pipeline to help keep track of all the articles I read. It (i) retrieves articles I saved to the Pocket app, (ii) scrapes article text, (iii) generates summaries, and (iv) writes the results to a Google Sheet. I now have all the articles I found useful in one convenient place, deployed on AWS so it ran on a schedule.
