Hi, I'm Waldo Ketonou

Business & Data Analyst | SQL • Python • R • Tableau | Turning Operations Into Insights

I’m a Business & Data Analyst with 18+ years of experience leading high‑volume operations and transforming complex business problems into clear, actionable insights. After nearly two decades managing multimillion‑dollar retail operations, I transitioned into analytics to formalize the work I’ve always loved: building KPIs, analyzing performance trends, optimizing processes, and using data to drive better decisions.

I specialize in:

  • SQL, Python, R, Tableau, Excel
  • KPI development & performance dashboards
  • Forecasting, budgeting, and operational analytics
  • Process optimization and workflow improvement
  • Data storytelling for non‑technical stakeholders

I’m currently building a portfolio of dashboards and case studies through WaldoSphere Group LLC, where I help small businesses uncover insights that improve efficiency, profitability, and decision‑making.
