About Me

Welcome to my website! I'm Sylvester Chun (Hong Wei), and I am a passionate individual who always wonders what solutions can be applied to solve problems around the world. Currently, I am a Senior Data Scientist at Micron Technology and a Master by Research (EEE) student at NTU focusing on information retrieval through large language models, targeting a December 2025 graduation. In my spare time, I am also working with Invigilo Technologies to help improve construction safety to reduce and hopefully eliminate the loss of human lives through workplace accidents.

I love to travel, hang out with friends and work on fun side projects to make my home more cosy and comfortable.

Senior Data Scientist at Micron

I am now with the Data Science team in Micron Singapore HQ at Woodlands North Coast Drive, and I have worked on yield enhancement/loss avoidance projects related to silicon wafer production. This is done through the development of tailored LLM Agents, Process modelling and the development of end-to-end prediction algorithms for a run-to-run deployment. In my time spent with the Data Science Team, I have enjoyed everyone's company as they are a fantastic group of people to work alongside.

Master of Research (EEE) in Information Retrieval for LLMs

I started a research Masters in Jan 2024, embarking on a journey to venture into the research field. As LLM Research is moving leaps and bounds in these few years, I quickly realized that that finding ways to leverage on the strengths of LLMs in other fields have yet to catch up. Since then, I have been fortunate to be able to have published a paper on leveraging LLM reasoning capabilities at MWSCAS 2024 in Springfield, MA. Currently, I'm exploring leveraging multi-modal LLMs to generate embeddings that can be useful in multi-domain recommendation systems.

IOT & Business Development at Invigilo Technologies

Since the first half of 2021, I joined Vishnu in his start-up Invigilo Technologies to explore providing effective safety solutions to construction companies with Computer Vision. I focused on projects involving lightweight data collection for our ML models that are going to be deployed on edge camera devices. I also travelled with the team to the Saudi and Japan outreach for Business Development needs to attend two safety conferences.

My Skillsets

Over the past few years of projects, internships, and jobs, I have gathered and improved on a few select skill sets with which I am relatively comfortable.

Python & Pandas, Tensorflow

The basics of any Data Scientist. As many internship and school projects that I have gone through require some sort of Data Analytics and Machine Learning, I have soaked my hands into python and tensorflow for about 2 years.

React JS & Django

This was needed when I had to take on software engineering projects while at my short stint with Imprint Energy during my overseas NOC Internship program. I contributed to an existing manufacturing web app by adding new pages and features to enable the production team to implement pipeline changes.

Java/Scala

I was exposed to Java in several modules in school that required software engineering. While working on big data systems, I wrote my first map and reduce function with Java too, before continuing to write more complicated scripts with Scala on Hadoop Distributed File System (HDFS).

C & C++

The first two coding languages that I have picked up. I learned the basics of Data Structures and Algorithms with C++, and up till this point, I still use it because of its efficiency compared to Python.
