What I'm looking for

I seek a data-focused role where I can apply Excel, Power BI, SQL, and Python to build dashboards, improve data quality, and drive data-informed decisions in a collaborative environment.

I am a results-driven Data Analyst with 2+ years of experience in data analysis, advanced Excel applications, dashboard development, and data governance. I have improved data accuracy to 99.9%, developed real-time monitoring dashboards, and produced reports that supported operational and strategic decision-making across healthcare, power generation, recruitment, and hospitality sectors.

I combine technical skills in Power BI, Power Query, SQL, and Python with strong data validation and visualization expertise to deliver reliable insights. I excel at cross-functional collaboration, training (250+ students in Excel), and implementing processes that reduce errors and operational costs, and I am eager to contribute data-driven solutions that improve product development and business outcomes.
