01. About me

As a Campaigns Analyst at DBS, I support targeted marketing efforts within the Treasures portfolio by leveraging data to drive revenue growth. Over the past 1.5 years in this full-time role, I have specialized in lead extraction using PySpark and SQL, enabling data-driven campaign strategies. I previously joined DBS under the Technology in Finance Immersion Programme (TFIP) and have since grown into a permanent position. I hold a First Class Honours degree in Data Science & Analytics from the University of Portsmouth, and bring a strong foundation in statistical analysis, data visualization, and pattern recognition across large datasets.

02. Interests and Hobbies

I enjoy gaming (currently obsessed with Starfield), watching explanation videos on YouTube about the unexplainable such as the universe, exercising and cooking. I am also very intrigued by new technology stacks and am constantly learning new things to keep up with the ever-changing world of technology. (Such as this website!)

03. Side Projects & Certifications

On the side, I enroll myself for courses to broaden my knowledge in the field of data science. I've recently completed courses in Azure, Discrete Mathematics and I am currently brushing up my Big Data competency (Apache Stack).
