About Me

I'm a seasoned Data Analyst with an MSc in Big Data Analytics from Birmingham City University, where I gained expertise in applied statistics, data mining, and advanced database management. I'm well-versed in Python, R, Hadoop, Spark, Tableau, and Power BI, and have a passion for using data to create impact.

My career foundation started with a Bachelor's degree in Computer Science from the University of Nigeria, Nsukka, giving me a solid understanding of programming, algorithms, and software development. This combination of computer science fundamentals and big data expertise allows me to approach challenges from both technical and analytical perspectives.

I'm certified as a ScrumMaster (CSM) and have completed specialized training in Power BI Essential Training, Data Analytics Essentials, Data Science Orientation, and KPMG's Data Analytics Job Simulation. My passion lies in transforming raw data into actionable insights and building solutions that drive meaningful business outcomes.
