Data Collection

Freelancer Overview

I am a medical student at Obafemi Awolowo University (500 Level, MBBS) with hands on experience in data analysis using Excel, SQL, and Python. I have completed real- world projects including Titanic survival analysis, iTunes physical to digital transition analysis, hotel booking analysis, and a Python ticket price calculator. I am a native Yoruba speaker with strong attention to details, developed through my medical and data analysis training. I am new to formal data labelling but eager to learn and contribute across text, language, and medical annotation tasks.

Labeling Experience

Ongoing paid structured data analysis training (Excel, SQL, Python)

OtherData Collection

Engaged in an ongoing structured data analysis training program focused on practical Excel, SQL, and Python workflows. Applied these skills to prepare for data labeling/annotation and AI training tasks by learning how to process structured datasets and follow detailed task guidelines. Completed multiple real-world mini-projects that reflect the reasoning and quality checks expected in data labeling. • Worked with structured tabular datasets in Python and Excel • Performed exploratory analysis to uncover patterns relevant to labeling decisions • Used SQL querying concepts (filtering, joins) to support data preparation • Practiced careful interpretation of results suitable for annotation review processes
