Mirriam Maseko

I’m a Data Analyst with hands-on experience cleaning, exploring, and visualizing data using SQL Server, Python, Power BI, Tableau, and Excel. I focus on making messy data usable—standardizing records, handling nulls, removing duplicates, and building clear datasets that support better decisions.

Through projects like DATA CLEANING IN SQL (housing records), DATA EXPLORATION IN SQL AND TABLEAU—COVID-19 (infection/death/vaccination trends), and dashboard work in Power BI and Excel, I’ve learned to combine rigorous analysis with compelling storytelling. In my ICT Intern role at Integrated Properties, I also supported data continuity through SQL Server (SSMS) database backups and integrity checks, while administering user accounts and monitoring cloud/local backups. I’m currently completing my BSc in Computer Science at the National University of Science and Technology, and I’m excited to bring this mix of analytics and data reliability to a team.
