Hey there 👋
I'm Jun Wei
MSBA at NUS · Building multimodal AI at GovTech
I build AI products that actually ship, mostly in healthcare and retail. Recently placed 2nd at the AI Innovation Challenge 2026 with SilverGait, a phone-camera frailty assessment for seniors. Came into 2026 not knowing what a VPC was; spent the year as a fervent Claude Code abuser and prolific Gemini caller, figuring out where AWS hides the actual error message, and shipping things anyway.
