What I'm looking for

I'm looking to apply SQL, Python, and BI reporting skills to turn business data into clear insights, while continuing to grow in data integrity, security, and governance.

I streamlined sales and customer reporting at Edge Line Tech Academy using SQL and Python, helping team leads make faster data-driven decisions.

I built three interactive Power BI dashboards for revenue, churn, and marketing performance, consolidating previously siloed reporting and increasing dashboard adoption.

I strengthen data integrity through standardized cleaning and validation workflows in Excel Power Query and Python, while translating weekly findings into clear recommendations for non-technical stakeholders.

Through independent projects, I’ve built sales performance dashboards and used K-Means clustering to segment customers into four behaviour-based groups. I’m also deepening my data integrity, security, and governance knowledge through an ongoing Cyber Security diploma.
