I develop dashboards that actually work—API-integrated, automated, and delivered with no guesswork or communication gaps. I help businesses achieve clear reporting, avoid surprises and reduce manual work by integrating data from multiple tools and sources into one streamlined view. I was a Demand Planner drowning in Excel, chasing numbers across CRMs and ERPs. Now, I build the pipelines, models, and dashboards I wish I had back then. My focus is on making complex technical concepts simple and actionable with an emphasis on long-term, successful partnerships. Cheers!
