What I'm looking for

I’m looking for remote or onsite opportunities where I can apply my data analysis skills to help businesses make smarter, faster decisions. I want to work with clients who value clean data, clear insights, and efficient support — whether that’s through dashboards, or reports.

I am a data analyst with a proven ability to turn complex business data into clear, decision-ready insights. Over the course of my career, I have delivered high-impact dashboards and reports that helped businesses identify hidden losses, assess risk, and boost performance.

Some of my key achievements include:

📊 Uncovered an 11% profit loss in high-selling products and regions through a Regional Sales Gap Analysis, helping business stakeholders redirect strategy and close performance gaps.
📉 Built a Credit Risk Dashboard to identify the likelihood of borrower default, supporting smarter, data-driven lending decisions.
💼 Developed a comprehensive Sales Dashboard that visualized business sales, profits, top-performing regions, product categories, and KPIs — enabling real-time monitoring and improved revenue tracking.

I work confidently with Excel, Power BI, SQL, and Python to clean data, discover trends, and create dashboards that support real business growth. My goal is to help teams move from scattered data to structured, visual insights that drive results.
