I'll show you the patterns hiding in your data, waiting to be found. 😉✨🔍 I'm a top rated data analyst and power bi developer who builds reporting that people keep using. Before analytics I worked as a senior visualization artist, so data visualization is where I am strongest: what the eye reads first on a page, and where the number that matters has to sit. 2,200+ hours on Upwork across 130+ projects at a 5.0 rating, and a business intelligence process that cuts manual data entry by up to 90%: one dataset, one definition per metric, a refresh that beats the meeting.

𝗗𝗘𝗩𝗘𝗟𝗢𝗣𝗠𝗘𝗡𝗧 (1 to 2 weeks): 70% of power bi developer work is inside the model, before the first visual. I ship in tickets you approve one by one, ending as an excel overview, a power bi interface or a google looker studio portal.
