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.

🌱 Learning: writing, communication skills, Computer Science, and meditation.

❤️ Passion (at night): independent Transformer/NLP research since 2019, reverse engineering/replicating and open sourcing ChatGPT, systems programming and Rust.

💬 Ask me: web development, "boring" technology 😄, etc.
