I'm a data analyst who turns messy business problems into clear, actionable decisions. From RFM segmentation models with 97% accuracy to dashboards that uncovered Rp 397.9M in cost savings — I work where data meets real outcomes.
About Me
I'm a Physics graduate from Airlangga University, Surabaya. My physics training didn't just teach me equations — it built the habit of breaking down complex systems, finding the signal in the noise, and communicating findings in ways non-technical stakeholders can act on.
Right now, I'm a Data Analyst at PT Berkah Tani Mukti, where I've built 8+ operational dashboards covering sales, logistics, fleet maintenance, and receivables. That work surfaced Rp 397.9M in cost savings and flagged Rp 25.17B in critical receivables through a 97%-accurate predictive model. Before this, I built a real-time safety detection system with PT Danone × Airlangga University — 90% accuracy, 10 ms inference time, deployed to production.
My approach is pragmatic: I don't analyze for analysis's sake. Every chart, every model, every dataset I touch is in service of a decision someone needs to make. I bring technical depth and business clarity to the table — and I take responsibility for the output from first query to final presentation.
