What I'm looking for

I seek a data analytics role where I can apply Python, SQL and BI tools to drive measurable impact, collaborate in Agile teams, and grow into advanced ML and data engineering responsibilities.

I am an undergraduate engineering systems student and SUTD Undergraduate Merit Scholar focused on data analytics, statistical modelling, and machine learning. I combine strong academic foundations in Data & Business Analytics and Probability & Statistics with practical, results-oriented internship experience.

At HTX, I automated end-to-end data workflows with Tableau Prep, cutting manual processing time by 40% and delivering interactive dashboards that supported $1B+ budget decisions. I also developed inventory-control analyses at SLB that reduced holding costs by 5%, and I ranked Top 6 in a Poverty Level Prediction Kaggle competition using XGBoost, stacking, and Bayesian optimization.

I enjoy building reliable ETL pipelines, crafting clear data visualizations, and telling data-driven stories to senior stakeholders. I work well in Agile/Scrum teams, value data quality and reproducibility, and am motivated to apply my technical toolkit to deliver measurable business impact.
