What I'm looking for

I seek a data role where I can build dashboards, clean and analyze datasets, influence decisions, and grow technically in BI and analytics.

I am a data analyst with hands-on experience in exploratory data analysis, dashboard creation, and presenting insights to stakeholders using Excel, Power BI, MySQL and Power Query. I have completed internships and short-term analyst roles where I built interactive dashboards, applied DAX and VLOOKUP, and supported research presentations and sales analysis.

I am outcome-focused and committed to turning raw data into actionable recommendations; I have worked across education, corporate and project-based settings and hold data analysis certificates from Brutech and Helmes. I enjoy continuous learning through workshops and data science community involvement.
