Hey, I'm Shawn.
I talk about AI and practical ways to become more efficient, focused, and productive!
By day I ship machine learning systems to production. Here I write deep dives on the computer science nobody looks at, and share the AI prompts I use to get more done with members.

Deep dives that respect you
The ranking model deciding what you watch, the math holding up the internet: real systems, real numbers, no hand-waving.

The Vault
A growing library of battle-tested AI prompts for planning, writing, coding, and killing busywork. Less busywork, more real work.

Built in the open
I ship my own products, Krevaya AI and vidfora, and the lessons from building them feed straight back into what I write here.
The Vault
Steal the exact prompts I use to work faster.
Not one-liners: complete systems with a role, a process, and an output format. Paste one into your AI assistant and it just works.
- 24 battle-tested prompts, organized by job
- Planning, email, meetings, learning, writing, and code
- Works with Claude, ChatGPT, or any capable assistant
- New prompts whenever I find something that works
No credit card. Just an email and a password.
