About



I am working on creator collaboration at Roblox. Prior to joining Roblox, I started Tym, a code collaboration startup which was then acquired by Roblox. I am passionate in technology and how it can be applied to the physical world, including climate tech.

I majored in Computer Science (Bachelors) and Management Science & Engineering (Masters) at Stanford. Before that, I served in the Singapore Army Intelligence Battalion as a logistic personnel.

Growing up in Singapore, I enjoy trying foods from different cultures and hiking in nature (to burn off those calories).

Portfolio

Research

Hyperdrive
Dec 2020
Independent research to create the building block for an automated filesystem. Used jupyter notebook extension to create a document extraction UI. Click here for more info. [GitHub]


Weak Supervision on Medical Images
May 2020
Wrote multiple labelling functions to identify the epicardium from MRI scans for the weak supervision framework. [Paper]


Projects

Zeus Notebook
April 2022
Built an in-browser IPython notebook with GPT copilot. The chat interface allows users to seamlessly move code from the notebook to the chat to ask questions and vice versa, make coding more accessible to everyone [Website]


Amperstand Live Shopping
March 2021
Collaborated with my friend to build out an MVP. Amperstand livestreames directly from your phone to a shopify store site. [Website]


My Maps
Oct 2020
My Maps displays a list of maps, each of which show user-defined markers with a title, description, and location. [GitHub]


Simple Tip
Oct 2020
A minimalistic tip calculator app in dark mode. [GitHub]


April 2019
A smart, data-driven system to manage brick & mortar 2.0. By analyzing video in real-time, we extract demographic insights, reveal trend comparisons, automatically deploy workers and allocate resources. [GitHub]


NaviCalc
Feb 2016
NaviCalc calculates the distance and bearing between checkpoints using the Military Grid Reference System (MGRS). Used by the Army Intelligence formation for military training.

Work Experience



SWE, Roblox
July 2022 - Now
Enhancing the collaboration experience of Roblox developers with Team Create.



Cofounder CTO, Tym
Aug 2021 - July 2022
Building the next-generation code collaboration tool that lets you collaborate with your team instantly. Raised a pre-seed round from Neo and Ovo. Acquired by Roblox. Click here for more info.



SWE Intern, Instabase
June 2020 - Sept 2020
Developed a document auto-extractor that utilizes program synthesis to create functions to extract fields of interest



SWE, Hypotenuse AI
June 2020 - Sept 2020

SWE Intern, Facebook
June 2019 - Sept 2019
Improved the quality of messenger story ads by reducing the number of bad ads delivered by 20%



Robotics Intern, Peanut Robotics
June 2018 - Sept 2018
Constructed an end-to-end semi-supervised reinforcement learning pipeline which improves the Generative Grasp Convolutional Neural Network using training data generated from a simulator



Logistician, Singapore Armed Forces
Feb 2015 - Dec 2016
Provided logistic support for our battalion during military exercises using spreadsheets. Developed a navigation app for the reconnaisance team on the side.

Tym


The current code development experience heavily relies on git, despite the fact that git was build for a different era. Git is a decentralized version control tool designed for open source projects with low frequency collaboration while most companies collaborate at a high frequency using a centralized source of truth.

That’s why we built Tym - a reimagination of the code development stack with real-time collaboration. We raised a pre-seed from Neo and Ovo in 2021.

As of July 2022, Tym has joined Roblox where we will have the opportunity to continue to pursue the same mission on a much larger scale!

Mockup of our product

Demo of our live-coding product. Share your Tym link with anyone and you can instantly collaborate with them on a VSCode-based editor. Built in 4 months.

Hyperdrive


An automated filesystem.

Filesystems today view documents as files to be stored and retrieved later. But documents serve a greater purpose - as stores of information to perform tasks. An automated filesystem should understand the intent and content of a document and automatically execute actions on behalf of the user.

This can be saving a downloaded file in the right directory with a human-understandable name. This can be extracting information from your receipts and automatically filing expense claims. This can be parsing your invoices to log them in your accounting software.

With an automated filesystem, users will be able to accelerate their workflows and conserve their mental energy for greater work.

As the first step, I've built out a document extraction system that is capable of extracting fields of interest from documents as part of my independent research. [GitHub]

Here are some snapshot of the system I've built:
