Lewis Moruri

I’m a Data Analyst with hands-on experience in SQL, Python, and Power BI. I focus on cleaning complex datasets and turning them into dashboards that help stakeholders make better business decisions.

In my Analyst Labs Africa Data Analytics Internship, I cleaned and validated complex datasets using Excel and Python (Pandas), improving data integrity and reducing downstream reporting errors by 55%. I also built interactive Power BI dashboards for campaign KPIs, cutting manual reporting time by 4 hours/week.

I maintain disciplined, auditable workflows by documenting analysis code and methodology for transparent collaboration across projects. I’m ALX Africa-certified, with additional training from Microsoft, McKinsey, and DataCamp, which strengthens how I approach structured analysis and problem-solving.

Now, I’m expanding into database administration and cloud data platforms—building toward PostgreSQL, SQL Server, and AWS—so my work can scale from reporting to stronger data foundations.
