About

I enjoy the part of data work where technical detail meets business context: defining useful metrics, cleaning imperfect data, finding the signal, and communicating it clearly. My foundation is in analytics and BI, and I am currently expanding toward data engineering to build more reliable end-to-end data workflows.

Explore data, define KPIs, and turn business questions into measurable insights. 		02 · Communicate

Build focused dashboards and explain findings in language stakeholders can act on. 		03 · Engineer
