About

A driven individual who loves to tinker and build things- from random and fun websites, to data science models, to functional 3D printed parts. Execution is the name of the game: even if I am not immediately familiar with the concepts or technologies required to get the job done, I am able to quickly pick it up and deliver.
Projects

AI / ML
Application of LLM and NLP Techniques to Model User Experience
Leveraging techniques from the natural language processing and large language model domains, I trained a BERT-style architecture from scratch to generate embeddings from sequences of user telemetry data. These could then be used for various tasks such as churn prediction, and conversion propensity.
Analytics
Automation of Conversion Funnel Reporting for Arbitrary User Journey Sequences
I developed a platform on top of Azure's Data Explorer platform (ADX) which allowed for business and product stakeholders to rapidly construct their own conversion funnel reports with arbitrarily defined flows. This removes the time-consuming ETL step of heavy clickstream data from the end user.
Analytics
On The Fly, High-Dimensional User Segmentation and Exploration Tool
I built a dashboard in PowerBI on top of a tabular model in Azure Analysis Services that allowed users to slice and dice user segments by over a hundred dimensions, and get instant insights on the segment demographics and transaction patterns.

    Grab
    Lead Data Scientist (Analytics)
    Throughout my time at Grab I have worked both under and with, different teams across the business- all under the umbrella of Data Science and Analytics. I have worn many hats during this time, and some of my more prominent and interesting hats include: - The Data Scientist Hat: researching and developing new models, frameworks, and approaches towards solving some of our trickiest business problems. - The Data Engineer Hat: developing and maintaining big data pipelines at scale, some of which can easily be more than a terabyte of data per day. - The Web Developer Hat: building platforms to serve data and visualization tools to our internal stakeholder for improving productivity: standardising analysis and providing replicable insight generation across teams.
