My Journey
in Data

Analytical and impact-driven Data Science & Modelling Specialist at BFI Finance with a strong Mathematics background (GPA 3.88/4.00). Expert in the full ML lifecycle — from engineering complex features in Trino/ODPS to deploying predictive models for mortgage and retail assets.

Proven track record in automating Daily Model Monitoring systems and real-time data infrastructure alerts via G-Chat integration. Certified TensorFlow Developer skilled at bridging advanced research (Fuzzy RBM, Deep Learning) with scalable financial solutions that optimize collection strategies and operational efficiency.

My academic journey at Universitas Padjadjaran forged a rigorous analytical mindset, further deepened through research in Operations Research and Robust Optimization, culminating in a thesis achieving 92% accuracy in malaria cell image classification.
