What I'm looking for

I'm looking to continue solving data challenges through data quality, governance, analytics, reporting, and reliable data solutions while expanding my technical expertise through practical learning.

I'm improving data quality, governance, reporting, and decision-making at FNB South Africa. I extract, analyse, and validate data using SQL, Hive, and Teradata, while supporting investigations and remediation.

I build Python scripts to automate data processes and create Power BI reports and visualisations for business stakeholders. I also conduct metadata classification, impact analysis, records management, and compliance support.

After starting as a Data Intern at FNB, I've built practical experience in data management, reporting, stakeholder support, and operational data processes. I'm currently pursuing a Bachelor of Science in Information Technology and continue developing reliable data solutions.
