What I'm looking for

I am seeking opportunities that foster growth in data analytics and machine learning, with a focus on innovative projects and collaborative environments.

As a dedicated Data Analyst with a strong focus on machine learning and data visualization, I have honed my skills in various roles across different organizations. Currently, I am working as a Machine Learning Data Annotation Specialist at Awarri, where I collect, clean, and evaluate diverse datasets to enhance machine learning model performance. My implementation of Reinforcement Learning from Human Feedback (RLHF) has significantly improved data accuracy and streamlined workflows, demonstrating my commitment to aligning AI outputs with human expectations.

Previously, I served as a Team Lead Data Analyst at Thels Impact Consultant, where I designed and implemented data visualization dashboards in Tableau, enabling real-time decision-making. My experience includes deploying advanced statistical analysis and machine learning algorithms in Python, which led to strategic recommendations that optimized marketing strategies. With a Bachelor of Science in Mathematics from the University of Benin, I possess a solid foundation in analytical thinking and problem-solving, which I apply to drive impactful results in my projects.
