What I'm looking for

I’m looking for a role where I can build reliable GCP-based data pipelines and apply quantitative ML for real business impact—favoring production rigor, measurable performance improvements, and strong collaboration.

I’m pursuing a Master of Data Science at Monash University, sharpening my foundation in statistical modeling, time series, and machine learning. I enjoy translating complex data problems into production-ready pipelines and decision-friendly analytics.

At Tata Consultancy Services, I engineered high-availability backend services using Python and Django for mission-critical flight operations, targeting 99.9% system uptime. As a Data Engineer on Google Cloud Platform, I designed scalable ETL pipelines with Cloud Dataflow and BigQuery, automating ingestion to reduce manual intervention by 40%, and optimizing SQL/data models to cut query costs by 20%.

My projects reflect that same production mindset and quantitative drive. I built a production-grade Lambda architecture for real-time crypto data with Kafka, Airflow, dbt, and DuckDB, and developed quantitative models and trading systems—delivering a 1.18 Sharpe Ratio and improving drawdown via risk parameter optimization.
