BI Analyst

Hello!


As a dedicated Business Intelligence Analyst with 5+ years, I bridge the gap between complex business challenges and data-driven solutions. I understand business needs, ask the right questions, and translate requirements into actionable insights that empower teams to make informed, effective decisions.


I specialize in ad-hoc analytics, building interactive dashboards, and automating reporting processes to streamline operations and save time. Using a systematic approach, I leverage tools like SQL, Python, Tableau and Superset to extract hidden insights from data, visualize trends, and support strategic initiatives.


I'm passionate about delivering measurable value - whether it's uncovering cost-saving opportunities or driving growth through evidence-based recommendations. Currently seeking new opportunities where I can contribute my analytical expertise to innovative teams.


Excited to connect - let's discuss how I can support your company data needs!
