About Khulekani Ngobese

I am a Data Scientist with a strong foundation in Python, SQL, Machine Learning, NLP, and Data Visualization. I completed the HyperionDev Data Science Bootcamp and hold Alteryx Server Administrator certification, combining analytical skill with systems integration experience. With over six years as a Technology Implementation Engineer at Diebold Nixdorf, I’ve developed a strong problem-solving mindset and the ability to translate data into practical business improvements. My background in Electrical Engineering gives me an analytical and process-driven approach to data science, allowing me to bridge the gap between technical execution and real-world impact. Core Skills: • Machine Learning (Regression, Classification, Clustering) • Python (Pandas, NumPy, Scikit-learn, spaCy) • SQL (Data Querying & Cleaning) • Tableau & Power BI (Dashboard Storytelling) • NLP & Text Analytics • Alteryx Server Administration Highlighted Projects: • Telco Churn Prediction: Built a recall-optimized model using Logistic Regression and Random Forests to identify at-risk customers and support retention strategy. • Customer Segmentation: Applied K-Means and PCA to identify behavioral clusters, creating actionable personas and marketing recommendations. • Service Desk Optimization: Designed a real-time technician allocation dashboard using live location data, improving SLA compliance and reducing response times. I’m passionate about using data to solve business challenges, uncover insights, and drive measurable improvements. I’m open to Data Scientist, Machine Learning, or Analytics opportunities where I can apply my technical and problem-solving skills to deliver value in innovative, data-driven environments.
