What I'm looking for

I am looking for opportunities that foster growth, innovation, and collaboration in data science.

I am a motivated Junior Data Scientist with hands-on experience gained through a 12-month Data Science Learnership at ExploreAI Academy, sponsored by MMI. My journey in data science has equipped me with a strong foundation in data cleaning, visualization, feature engineering, model building, and evaluation. I am proficient in Python, SQL, and Power BI, and I have a solid understanding of core machine learning algorithms.

Throughout my learnership, I completed an intensive program that involved end-to-end data science workflows. I successfully built and evaluated various models, including classification, regression, and clustering, while utilizing techniques like PCA and t-SNE for dimensionality reduction. My commitment to leveraging data to solve complex problems drives my continuous learning of new technologies and methodologies in the field.
