Field notes.

Short pieces I post to LinkedIn and keep here in full — selected, not exhaustive. The arguments that drew the sharpest replies, with a line or two from me on what I'd add today.

Strong opinions on multi-agent architectures

The pitch to build an army of specialized agents and delegate between them doesn't work — you get a distributed monolith. Treat sub-agents as dependencies, not separate services.

“You can't enforce API contracts when your interface is natural language.”

How I interview machine learning engineers

How I run ML/AI engineering interviews to find people who can actually ship: no trivia, make the candidate the expert, then stay relentlessly curious.

“Make them the expert, then get relentlessly curious.”

Anthropic is converging on code, not tool calls

MCP, then Skills, then code-execution benchmarks: Anthropic's guidance keeps trending toward pairing LLMs with executable code instead of chaining tool calls. Prompt-and-pray is ending.

“Separation of concerns is back in style.”

Your AI platform is too data-hungry

A user called Rasa 'data-hungry' — not from benchmarks, but because our docs stressed training-data quality. A lesson in how advocating best practice can hurt perception.

“Sometimes the market will punish you for trying to be helpful.”

Don't try to convince your sales team

If you're in product or engineering, don't pitch your roadmap to sales. Good reps are rightly skeptical of features until a real prospect gets excited.

Great product managers combine restraint and ingenuity

Restraint, so you don't fall in love with your own clever solution; ingenuity, so you actually commit to a direction. PMs need both, or they miss the mark or spin their wheels.

“Without both, you're either missing the mark or spinning your wheels.”

From 30 under 30 to 2 under 2

Forbes once put me on a 30 Under 30 list. I'm now in a more demanding club: 2 under 2.

“I'm now in a different club: 2 under 2. I can tell you it's much more demanding.”

Why I write a weekly newsletter for my own company

As a founder you get pulled into more conversations than anyone else at the company. Writing up what you're seeing every week — in four short sections — turns that information privilege into shared context, and a way to influence without dictating.

“It's also a way to influence without dictating.”

Everything that can be code, will be code

A Slack question about hiring a video editor turned into a Remotion + Claude Code + Whisper pipeline for making social videos — the moment video editing collapsed into code for me too.

“Saying "make this transition snappier" and watching it happen is magic.”
