Featured Project

Melbourne Electricity Market Analysis

End-to-end data platform built on 3 years of Victorian electricity market data. Raw data from three public APIs flows through a medallion pipeline on Azure Databricks, powers three production ML models, and surfaces as a four-page Power BI dashboard with a live FastAPI endpoint.

Medallion architecture (Bronze → Silver → Gold) on Azure Databricks with Delta Lake

Live pipeline: hourly AEMO price ingestion, nightly silver refresh, continuous production updates

Price prediction model (XGBoost) achieving R² 0.89 with $14.90 MAE on wholesale prices

Demand forecasting (CatBoost) with 2.5% MAPE and R² 0.98 on test data

Spike classifier with 0.99 ROC-AUC using Platt calibration on 12.4:1 imbalanced classes

Summer Paradox discovery: renewable generation falls on hottest days (29% vs 55% on cool days)

WHO I AM

About

Data Engineer at Zietpass and Data Scientist with a Master's degree from the University of Melbourne and 2 years of software engineering experience at Tata Consultancy Services.

I'm fascinated by the intersection of AI and real-world impact—building systems that don't just crunch numbers, but genuinely help people make better decisions. Whether it's analyzing 100,000+ social media posts to uncover sentiment patterns or automating mental health training evaluations, I thrive on turning messy, complex data into clear, actionable insights.

My approach combines rigorous engineering with curiosity-driven exploration. I believe the best solutions come from deeply understanding both the data and the humans who will use it. Currently exploring AI agents and LLM applications— the frontier where automation meets intelligence.
