What I'm looking for

I am looking for opportunities that allow me to grow in machine learning and data analysis while contributing to impactful projects.

I am a dedicated data labeling specialist with hands-on experience in CVAT annotation and QA validation for machine learning projects. My journey in this field has allowed me to develop a keen eye for detail and a strong commitment to quality. I have successfully annotated over 10,000 text samples for sentiment analysis and conducted audits that identified and corrected 15% of labeling errors, ensuring high accuracy in data preparation.

My educational background in Electrical Engineering from Kenyatta University has equipped me with a solid foundation in machine learning fundamentals, data structures, and signal processing. I thrive in collaborative environments and am passionate about leveraging my skills to contribute to innovative projects that harness the power of machine learning.
