Hi, I'm Walter.
What I'm working on
I'm helping readers read in short form with an app called BookSlice.
I feel concerned that as AI models grow, we (including me) are reading fewer books than before, struggling to understand metaphor, and becoming overreliant on large language models.
Technology should enhance human potential, not replace it. My work focuses on building apps that make us better, not worse.
0-to-1 product development
I also do 0-to-1 product development for startups and solo entrepreneurs. Book a free discovery call.

About
I'm currently on a sabbatical to work on my own projects.
This year (2025), I tried building a healthcare app and applied for a few grants to get a research trial going with researchers at NUS (2 professors, 1 research fellow). We're still working on it.
Last year (2024), I learnt how to code and built several apps. BookSlice was my most profitable appβit was supported by Microsoft for Startups, featured in The Straits Times, and placed 2nd on ProductHunt. I also built Malaysia's #1 website for Pengajian Am (ranked #1 on Google), and a travel visa app that was featured on Mint, India's #1 finance news site.
From 2020 to 2023, I worked as a Product Manager at igloohome, leading teams of engineers and designers (30+ persons) on their consumer roadmap. We launched 15 new software and hardware products and grew revenue by $1M+.
My formal education is in mechanical engineering at NUS and liberal arts at USP.
