Hi, I'm Alex 👋

📍 San Francisco ↔ Singapore | 🛠️ Builder by nature | 🚀 Ex-Calendly · Ex-Wellfound

These days most of my open-source AI work and research happens at FWD AI, an indie lab focused on practical AI and local-first software.

15+ years of turning ideas into shipped products, built with the stack that fits the problem. AI writes a lot of my code now. I still own every line of it.

Featured Projects
