About
I enjoy working at the intersection of software and hardware, applying AI and algorithms to build intelligent systems.
Profile
Currently, I'm a Full-Time National Serviceman.

I began tinkering with robots and computers after joining the Robotics Club CCA in secondary school. There, I developed my interest in programming and oversaw CCA training as the Vice-Chairperson. In JC, I continued to hone my skills in technology, attaining the Engineering & Tech Programme Scholarship as well as becoming Vice-President of my STEM CCA. Taking part in the Nanyang Research Programme and research competitions allowed me to experiment with IoT devices and statistical modelling. My interest in Competitive Programming led me to achieve a Silver medal at the National Olympiad in Informatics. Beyond school, I continued to pursue robotics and was able to represent Singapore at the International Final in Türkiye.
Achievements
My journey competing in various olympiads and hackathons.
Computing & Robotics
HackOMania
2026
We built PABand, a wearable device to enhance the Personal Alert Button with new features such as fall detection and geolocation services. We also built a dashboard to improve the efficiency of screening through automated triaging with real-time two-way voice communication.
- 1st in GovTech Challenge
- Best Hardware Hack
Hack&Roll
2026
We built Rewind, an immersive 3D web application that allows users to explore the rich history of Singapore through an interactive virtual environment. By combining modern web technologies, AI-powered storytelling, and archival data, we brought the past to life.

Projects
Here are some of the projects that I've worked on, ranging from robotics to web apps.
- All
- Games
- Robotics
- Web
We created 3D Gaussian Splats generated by Apple's SHARP model based on historical images and context scraped from National Archives using Exa.ai. It performs semantic search using custom parsing functions to obtain users' intent by extracting keywords from natural language queries to obtain deep background information.
A smart emergency response system for elderly residents in Singapore. When a senior activates their Personal Alert Button (PAB), PABand connects them to an AI voice agent that triages the situation in real time — in whatever language they speak — and alerts operators who can monitor, intervene, or dispatch help.
The 2021 mission mainly involved collecting and depositing randomly arranged cars at their respective locations while avoiding obstacles like barriers. I learnt various sorting and searching algorithms to optimise the collection of cars and implemented graph traversal algorithms to determine the shortest path to take.
