Data Scientist

Data Analyst

Data Analyst and BI Developer specializing in production Power BI dashboards. At PT Merak Chemicals Indonesia, I shipped three dashboards for marketing leadership covering 600+ global PTA producers, 300+ PX producers, and Indonesia's petrochemical trade flows—building 30+ DAX measures and 14 custom Deneb Vega-Lite visuals on star-schema semantic models, and setting the department's BI development standard.

My experience spans the full data stack: Power Query M, DAX, and Deneb Vega-Lite for BI; SQL and Python for data engineering and ETL (1M+ healthcare records cleaned and modeled); and deep learning for ML (LSTM fake-news classifier at 85%+ accuracy, plus a CNN-BiLSTM depression-detection thesis presented at ICoDSA 2025). Informatics graduate from Telkom University, GPA 3.57.

I'm looking for roles in Data Analytics, BI Development, Business Analysis, or Data Science.
