What I'm looking for

I'm interested in software development and automation, where I can apply my experience with Python-based browser automation and Excel-driven data processing.

At The Agency Source, I annotate, tag, and review 300+ data entries daily, following client guidelines and quality standards. I audit submitted ads, give corrective feedback, and train colleagues on workflow and quality expectations.

In a freelance Python Automation Project, I developed browser automation for data extraction and processing, with Excel-based workflows to organize records. I also created a terminal-based C program for matrix operations as part of my software engineering studies.
