Hi there 👋
I make people's lives easier with software.
I started my career as a full stack developer. I'm currently a backend software engineer and AI engineer. I was an entrepreneur, Antler (VC+accelerator) alumni, and fast.ai fellow. I have broad experience with product engineering at startups and consulting — building enterprise and consumer Internet applications for over a decade. I've launched and maintained over 15 web/mobile apps and AI products worldwide.
I prefer boring technology and simple solutions over exciting technology and complex solutions. I'm a Grug Brained Developer one way or another. 
I've written in my blog about my 16 years working in tech.
