What I'm looking for

I'm seeking remote or freelance work in data annotation, data labeling, AI data evaluation, classification, cleaning, validation, extraction, web research, web scraping, and dataset preparation.

I use Python, Pandas, and NumPy to clean, transform, validate, and prepare real-world datasets for analysis.

In my online retail customer segmentation project, I built an end-to-end analysis pipeline, audited data quality, filtered invalid records, and examined sales, product, seasonal, and geographic trends.

I performed RFM customer segmentation, identified high-value clients, and calculated Average Order Value. My practical projects also include web scraping, structured data extraction, visualization, aggregation, missing-value handling, regex-based text cleaning, and duplicate removal.

As an Information Systems Lecturer at Wollo University’s Kombolcha Institute of Technology, I teach information systems, guide practical IT projects, work with structured research datasets, and prepare institutional reports and technical documentation.
