Hi, I'm Walter!

My current focus is on Knoyo Health, a HIPAA-compliant clinical notes app to help patients remember and organize their healthcare information.

Last year (2024), I built:

• BookSlice, read 3x more books by turning your books into text messages (📕->💬)
• PengajianAm.com, learn STPM Pengajian Am with the largest question bank in Malaysia and get a better score (money-back guarantee)
• Luna, a friendly Discord bot that makes voice calls less awkward
• PesanBot, split bills instantly by taking photos of receipts
• img2icns.com, convert any image to ICNS for developers making macOS apps
• SojuHWP, open source Korean legal document reader for macOS
• VisaHacks.in, see visa requirements instantly for Indian passport holders

From 2020 to 2023, I worked as a Product Manager at igloohome, where I led teams of software engineers and designers (30+ persons) on the following projects:

• Bridge, proprietary Bluetooth/WiFi gateway for smart locks
• Padlock 2, world's toughest smart padlock
