Data Scientist focused on machine learning and predictive analytics that drive results.
What I'm looking for
I’m a Data science and AI operations professional, with experience in machine learning, predictive analytics, and data annotation workflows across remote-first technical environments. I develop analytical models, ETL pipelines, and data-driven solutions using Python, SQL, and scikit-learn—prioritizing feature engineering, workflow optimization, and quality assurance.
As an Applied Data Science Intern (WorldQuant University), I optimized predictive model performance by 40% and delivered REST API endpoints and Plotly Dash dashboards to improve visibility into forecasting, customer segmentation, and behavioral analytics insights. As a Data Annotation Trainer & Consultant (Skillshub Africa), I trained and supervised 50+ annotators, raised task success rates to 96%, and improved dataset consistency and machine learning training efficiency by 20%.
