Nwaeze Cosmas Kelechi

I am a dedicated Data Scientist with a strong foundation in machine learning and ethical AI practices. I hold a Bachelor of Science degree from Chukwuemeka Odumegwu Ojukwu University and am currently pursuing an Applied Data Science certification from WorldQuant University. My professional journey began as a Data Analyst at Zefra Global Ltd., where I conducted exploratory data analysis and created interactive dashboards to support decision-making processes.

As a Data Scientist intern at Zefra Global Ltd., I developed and deployed machine learning models for predictive analytics, engineered data pipelines, and implemented feature engineering techniques to optimize model performance. I also built interactive dashboards with Plotly Dash and integrated FastAPI and Uvicorn to serve ML model predictions via a scalable web API.

I have a passion for solving real-world problems through data-driven solutions. My projects include predicting housing prices in Lagos, stock price prediction using time series forecasting, and customer segmentation for market basket analysis. I am committed to ethical AI practices, ensuring bias mitigation and computational efficiency in all my work.
