Brian Muthuri

I’m a detail-oriented Web Data Analyst and Data Annotator with hands-on experience in structured data collection, web research, and high-quality data tagging. At Wealthreel, I evaluated and labeled text strings and user intent queries on data annotation platforms to help train machine learning models.

I strengthen outputs through rigorous data quality assurance, identifying formatting errors and dataset edge cases, while staying fully compliant with data privacy and confidentiality requirements. I also build practical Python and SQL tools—using Pandas and Regular Expressions—to clean, filter, and convert raw files into structured, automation-friendly datasets.
