About

I'm now living in San Francisco! I'm really excited to be here, and I'm hoping to meet more people.

Before I got my current job, I co-founded Knoyo Health, a company that built custom enterprise AI software for healthcare. The company is no longer operating.

Prior to Knoyo Health, I had a lot of fun building a book reading app called BookSlice. It was my most successful indie app, and grew to 500+ users in a week.

Over the years, I've also built Malaysia's #1 website for Pengajian Am, which at its peak ranked first on Google with 24.9k monthly visitors; a travel visa app that was featured on Mint, India's #2 business daily with 42 million monthly readers; and open source Dart libraries that see 1,500 weekly downloads.

My interest in product design and engineering started in 2020 - 2023, where I worked my first job as a Product Manager at a smart lock startup called igloohome. I had the incredible opportunity to work on the consumer roadmap, and support a 30+ person engineering and design team. We launched 15 new software and hardware products and grew revenue by more than $1M. I'm also a named co-inventor on a patent application for one of the features we built.

Before my first job, I studied mechanical engineering at NUS and liberal arts at USP. I'm grateful that the university let me explore a wide range of subjects. I remember one time I took too many classes and had to write a letter asking for an exemption to try more subjects! While at NUS I took a class on meta-ethics, dissected a brain, implemented a quantum sorting algorithm, read Hegel and other philosophers, and studied a bit of political science and linguistics.

Prior to moving to Singapore, I grew up in a city called Kuching. It is a beautiful city with a rich history (and great food). I had a lucky encounter in secondary school, where I met a senior who gave me life-changing advice. He motivated me to study hard, and this helped me become the top scorer in the national chemistry olympiad and rank 95th in the national math olympiad. Outside of studying, I also played chess competitively at the state level, and played violin for two ex prime ministers! Most of the academic stuff happened pretty late (I was a late bloomer). I spent way too much time playing video games, so by the time I found out about these competitions I was also too old for the age cutoff for IChO 😭.

Thanks for reading this far!
