PENGCHENG D.
Data Engineer/Processing
I worked for over 4 years at a data company specializing in urban planning and development, where I specialized in handling data related to demographics, geography, POIs, and more. Initially, I wrote articles on data analysis, then transitioned to designing and developing SaaS-based data visualization products, and later focused on data engineering. My responsibilities included, but were not limited to, ETL tasks such as data extraction using Python (including extraction from images, PDFs, and other unstructured data), data cleaning, data analysis and mining, and visualizing data using frontend languages such as HTML/JS/CSS. If you have any needs related to data work, I can help.
