Hi, I'm Triana Umi Ma'rifah
Every dataset has a decision hiding inside it. I find it, model it, and turn it into a dashboard people can actually act on. Business Intelligence Analyst and cum laude graduate from Telkom University, experienced in turning raw, messy data into clean, decision-ready insights using SQL, DAX, Python, and AI-augmented analytics.

About
Most data isn't hard to collect, it's hard to trust. Numbers live in different systems, definitions don't match, and by the time someone needs an answer, nobody's confident in the dashboard in front of them. Closing that gap is what I care about most.
I graduated as Telkom University's Best Graduate in 2025 (GPA 3.92, Informatics Engineering), and I've built my skill set around exactly that problem, designing data models that make sense, writing DAX measures that hold up under scrutiny, and building live SQL pipelines that don't break when the business needs them most.
That experience spans corporate finance, HR analytics, and e-commerce, from consolidating financial statements across 8 subsidiaries to building a Human Capital dashboard from raw employee data. Different domains, same core skill: turning "I think" into "I know." I'm not looking to specialize in one industry, just to keep doing that, wherever it's needed.
