My name is Rosette Tiego Sihlangu. I am a Data Analyst specializing in business analytics, BI storytelling, and data‑driven decision support. I work across Excel, SQL, and Power BI to transform raw financial data into clear, actionable insights. My strength lies in building clean data models, designing meaningful KPIs, and developing executive‑ready dashboards that diagnose business performance.

I bring a blend of analytical rigor and business understanding, supported by hands‑on experience in financial ratio modeling, DAX measure creation, and narrative‑driven dashboard design. My work focuses on clarity, accuracy, and insight — ensuring that complex business information becomes accessible to both technical and non‑technical stakeholders.
