I’m Harrison Weru, a Kenyan data analyst dedicated to transforming raw data into meaningful stories that drive decisions. Over the past few years I've developed an extensive skill set to prepare for a future career in the tech industry. In particular I've had professional training in data science, project management, and technical writing. With a background in Economics and Statistics, I use data visualization, statistical methods, and machine learning to get insights out of data.
My love for data analysis started at Mount Kenya University where I took an econometrics class. It inspired me to start learning advanced excel, SPSS, Stata and R because of their capabilities to perform complex regression modelling at a faster and more accurate way. However, the data landscape is changing. AI and cloud computing are transforming the way data is accessed, transformed and analysed. Therefore, I have taken a deliberate step to enroll in Oracle's Data and AI learning paths to ensure my skills remain relevant.
In my GitHub profile, you can find the projects I have completed to demonstrate the application of different methods in practice. Connect with me to discuss the projects, potential collaborations or anything else.
✔ Query and manage data using SQL databases
✔ Clean and transform data using spreadsheets, Python and R
✔ Apply statistical techniques to explore data
✔ Create visualisations and dashboards in Tableau, Power Bi and Looker Studio
✔ Find patterns, build and deploy predictive models
✔ Version control using Git and GitHub
✔ Leverage cloud storage (AWS, GCP, Oracle) for scalable data storage and management
✔ Report writing and PowerPoint presentation
✔ Communication skills
✔ Time management
✔ Continuous learning
Data wrangling is not glamorous but essential. Every strong analysis begins with clean data. I take pride in making raw data analysis-ready to ensure models and visualisations are built on solid ground.
I bridge the gap between raw data and real-world decisions by translating complex datasets into actionable insights, presented in dashboards to help users grasp key trends, patterns, and priorities at a glance.
It’s not enough to have insights, they must be understood to drive action. I am interested in turning insights into clear narratives and presentations that support decisions across technical and non-technical audiences alike.
