Freelancer Overview

I am a data analyst with hands-on experience in transforming raw data into actionable insights, specializing in data cleaning, labeling, and reporting using tools like Power BI, Excel, SQL, and Python. My background includes practical projects such as building a sales performance dashboard and conducting sentiment analysis on YouTube comments, where I applied techniques in data preprocessing, classification, and visualization. I have a strong foundation in analytics from CWW Tech Africa and have worked with both structured business data and unstructured text data, making me well-equipped for roles involving data annotation and AI training data preparation. My attention to detail, analytical thinking, and collaborative skills ensure high-quality, reliable datasets for machine learning and business intelligence applications.

I worked on an interactive scripted audio task where I read my assigned lines aloud and the AI responded accordingly. Quality criteria included reading exactly what was written with a clear voice, accurate pacing, and no background noise. The goal was to help create high-quality audio data by ensuring that recordings matched the script word for word.
