Test-n-Tell - tiny apps, Big ideas

  An AI agent is like a super obedient engineer. It does whatever you ask. It rarely challenges you. It rarely pushes back. It rarely says: “This is a bad idea.” And if it goes off script, well, that’s probably because your instructions were too vague. Finally, executives got what they always dreamed about: a builder who simply builds.

The job of a product manager is already changing. We use AI more and more in our daily work, and there is no sign of this slowing down. Writing, research, analysis, prototyping, summarising calls, checking requirements, preparing strategy docs, testing product ideas - all of it can already be supported by AI.

  A mistake many companies make when hiring Product Managers is that they overvalue industry knowledge.

  When I started vibe coding, I had a budget in mind. I knew I needed to learn a bunch of new AI tools, and that would cost something: subscriptions, hosting, third-party tools, APIs. And it did cost me a bit… then a bit more… and finally a lot more. So here’s me sharing a few things I learned (and paid for) so you don’t have to.

  There’s a persistent myth in product development: that what you ship is the roadmap. In reality, what you ship is the organisation that built the roadmap.

  Spreadsheets are among the most powerful tools in modern organisations. They clarify plans. They align teams. They make trade-offs visible. They help leaders reason about complexity. But they also create one of the most dangerous illusions in product development: the illusion of certainty. 

  I've been doing a lot of vibe coding lately, and one tech stack emerged for me as the most practical. Spoiler alert 1: it's Firebase + Codex + Google Cloud. Spoiler 2: tomorrow it could change.
