Who I Am

About Me

I am a data-driven professional transitioning into Business Intelligence and Financial Analysis, with a background in banking and internal controls. I turn raw data into clear, actionable insights using Power BI, SQL, Excel, Tableau and DAX and I actively use AI tools like Claude and ChatGPT to accelerate analysis and solve complex data problems faster. I am passionate about banking and fintech, continuous learning and building solutions that solve real financial problems.

Outside of analytics, I love all things fashion and sewing. I also run a fashion business and occasionally create content that blends creativity with purpose.
