What I'm looking for

I’m seeking to apply my expertise in a dynamic and growth-oriented environment—turning KPIs into clear visual insights and using Python, Power BI, and machine learning to support data-driven decisions.

I’m a Data Science graduate at ALX Africa with a National Diploma in Business Management, currently pursuing a BSc in Computer Science at the University of the People. I bring an analytical mindset and a strong problem-solving approach to turning complex data into practical decisions.

I leverage tools like Power BI for KPI extraction and visualisation, combining it with Python, R, MySQL, Excel, and DAX. I’m comfortable working across the full analytics workflow, from understanding requirements to presenting findings in a clear, stakeholder-friendly way.

My work also includes diagnostic, predictive, and prescriptive models for data processing and machine learning. I’ve built capability using machine learning frameworks, deep learning (CNNs), natural language processing, and big data technologies like Apache Spark and Hadoop, alongside data pipeline development and cloud computing (AWS, Azure). I’m also exploring emerging technologies such as augmented reality (META).

Beyond technical training, I’ve developed execution and collaboration skills through real-world roles—facilitating communication programs that improved stakeholder engagement by 15%, running an entrepreneurial operation that increased revenue, and volunteering to support rehabilitative programs while analyzing datasets with Python and Excel. I helped start a Smoke Quitting Program that dropped the smoke rate by 30%.
