What I'm looking for

I seek a data role where I can build forecasting and BI solutions, collaborate cross-functionally, and drive measurable operational improvements in a growth-focused team.

I am a strategic and analytical data analyst with over two years of experience turning complex datasets into clear, actionable insights that improve operational performance and inform executive decision-making.

I have built forecasting and beginner machine-learning models in Python and R, developed Power BI dashboards, automated workflows with Power Automate, and used SQL and Excel to clean and consolidate large transactional datasets. My work has reduced stockouts and expired stock, cut procurement costs, improved margins, and increased customer retention across pharmacy and retail projects.

I collaborate closely with stakeholders to define KPIs, translate requirements into visual stories, and produce documentation and business cases that support scalable process improvements and data governance. I am motivated by solving operational challenges and driving measurable business impact.
