Hello! I am Wen Hao, a self-taught data science enthusiast. This page contains a broad range of works that I have completed for learning and showcasing purposes, spanning from data science projects that aim to address business problems through analysis and predictive modelling, to creating simple applications that makes use of machine learning tools for fun.


Experience

Data Science Teaching Assistant | Vertical Institute Oct 2021-Dec2022 | Feb2024-Present

Coached new learners in Python programming and data science skills providing regular feedback and guidance. Collaborated with instructors and team members to implement developmentally appropriate learning experiences for bootcamp-style classes, accommodating up to 40 students.

Production Support Specialist | Wiley Edge Jun 2022-Dec 2023

Provided comprehensive support for the production environment of a multinational investment bank’s banking platform across 3 main applications. Played a key role in documenting known issues, devising innovative workarounds, and enhancing the efficiency of the onboarding process.

Machine Learning Intern | Central Provident Fund Board Dec 2020-Jun2021

Predicting Survey Nonresponse - Designed and deployed a machine learning model achieving up to 80% accuracy in predicting nonresponse propensities for upcoming surveys. These predictions guided fieldwork interventions to enhance survey response rates.
Predicting Optimal Contact Time - Augmented the nonresponse model to identify optimal contact timings for respondents, enabling fieldwork teams to plan interactions more efficiently.
Natural Language Processing Model Enhancement - - Improved an in-house text classification model by adjusting outputs, streamlining deployment processes, and updating classification labels to align with the latest government standards achieving a model precision of 85%.
In-house Data Management Software Enhancement - Debugged poorly implemented features and streamlining processes of an in-house data management software, reducing runtimes by almost 90% on average.

Teaching Assistant | Nanyang Technological University Aug 2019-Dec2019

Educated a group of 20 international bridging scholars in a practical laboratory module, ensuring their understanding of experiment principles and proficiency in verifying, presenting, and explaining findings in reports.
