What I'm looking for

I'm seeking data roles where I can build dashboards and models that drive strategic decisions, work cross-functionally, mentor others, and continue growing technical and BI expertise.

I'm a data professional with over two years of experience turning data into actionable business insights, working across analytics, data science, and business intelligence. I combine technical tools like MySQL, Python (Pandas, NumPy, Matplotlib, Seaborn, Plotly), Power BI, and Tableau with strong business judgement to track KPIs and spot unusual patterns that drive better decisions.

I've collaborated with cross-functional teams in sales, inventory, finance, and procurement to deliver dashboards and reports used by executives and sales teams, and I led initiatives that reduced stockouts by 17% and cut reporting lead times by 22%. I also build KPI frameworks, automate reporting, and apply process optimization to improve forecasting and operational efficiency.

I'm committed to delivering data solutions that create measurable business impact and sustainable growth, mentoring aspiring analysts, and continuously expanding my technical and domain expertise to support strategic decision-making.
