Write Your Self-Review Like It's a Keynote

Let’s learn to write a developer’s semi-annual performance review, using WWDC26 as our worked example. You didn’t screw up your own AI models and end up shipping a competitor’s. You “built a new foundation-model architecture in collaboration.” a new architecture built on foundation models developed in collaboration with Google using the technologies behind the Gemini family. You didn’t throw Apple Intelligence in the trash because it was so bad. After a “deep” engagement, you unlocked a “huge upgrade” to Apple Intelligence. ...

The Month of Blog Posting Is Done — See You in June

That’s it. The month of blog posting is done. A whole stretch of near-daily posts about tokenmaxxing, feral agentic loops in tmux, reviewers who can’t read code, Builders in a brave new native world, managers converted into ICs, and the slow realization that everything, apparently, got better with AI. Thanks for reading along. Writing a little every day turned out to be its own kind of tokenmaxxing — except the tokens were words, and for once I tried to make every one of them count. ...

The Reviewer Can't Read Code

Recently I pushed code to production without reading it. Looked at the title. Looked at the description. Asked an AI agent to review it. The agent wrote something or other. Out of the corner of my eye I caught a green emoji — click, click — and the request flew off to prod. It was a planned trick, to be fair. I know the codebase by heart, there are plenty of tests. A kind of Russian roulette: where you used to switch off a data center and watch what fell over, now you commit with your eyes closed. And if it falls over, you say it was a planned stress test of the AI pipeline. ...

Multiply Your Salary by 0.11

Who even counts tokens? Who counts the number of servers? Who counts the seconds per request? Who counts anything anymore? If it doesn’t matter how much you pay Anthropic or OpenAI for tokens, if it doesn’t matter how many instances are running on Amazon, if it doesn’t matter that an Azure function cold-starts for 10 seconds every single time — then the programmer probably doesn’t particularly matter either. Replaced one with another. The other with a third. Fired the third. Hired a freelancer with a Max subscription to Claude Code. It doesn’t matter whether the freelancer holds one job or ten. Doesn’t matter if they’re frontend or backend. Doesn’t matter the language, the framework. Only the subscription matters. ...

Brave New Native World

If developers already have their silver bullet — TypeScript — then managers have just found a new favorite: the AI-Native Team. It’s this idea that a small team can be as productive as a big team. Sounds like something you’ve heard before? Well, here’s the important addendum: as productive as a team of 50 people. So not even a team anymore — a whole organization. A department. The Builders The AI-Native Team doesn’t write code itself. It manages agents. It sets up agent factories for developing and delivering code. ...

No One Left to Say No

I have a colleague who seems to have lost his mind on the AI wave. Before this he was an average engineer. He built good tools. Sometimes cool engineering decisions, sometimes not so much. All as usual. An engineer like any other. He played politics very well. Got promoted to Staff. Sat in meetings, aligned, synced, did his soft-skill things. All good. Then AI coding arrived And he probably decided: here’s my chance to level up the hardcore skills. Now I don’t need to negotiate. I don’t need to sit in meetings, or write design docs. I don’t need other people at all anymore. I can do everything myself. ...

Big, Big Tech

People go into Big Tech for all sorts of reasons. Big projects. Big tasks. Big tools. A big ego. A big algorithmic past. In short — everything has to be big. Big. Big Tech. Only one thing stayed big But it just so happens that in recent years the only things that stayed big are the layoffs. The instability. The chaos. The politics. You go on vacation — and your project gets rewritten. You miss a meeting — and the platform gets migrated onto a different platform. ...

Skill Issues

The morning starts with going through the logs — the errors that piled up overnight. Nothing complicated. You read the errors, you go into the code, you see why a wrong parameter came in here, and over there why a parameter is missing instead. You commit. Note to self: check again in a couple of hours. At the meeting you describe what you spent your time on — and the response is an idea. Maybe you need a skill? Look: Claude Code will do all of this for you, and you just review the merge requests. We schedule the skill with cron and that’s it. ...

All Hands on the Prompt

A bug comes in from users. Your program crashes with an error at some indeterminate moment, for unclear reasons. (Are there ever any other kind?) It’s serious. Lots of users complaining. It’s urgent — every engineer drops what they’re doing and piles onto the task. What’s the CPU doing? Which processes are running? Are there logs? Are there repro steps? What about the dump? Etc. The war room Only they’re not exchanging files anymore. They’re exchanging prompts. ...

Agile Wasn't Flexible Enough

A task’s status updates itself, automatically, from the pull request. Sprints have been replaced by an optional weekly call. There’s no sprint planning either — you have an LLM generate a one-page design doc for the feature, and that’s the whole ceremony. Agents work the codebase autonomously. They write the tests. They review the code. They open small pull requests and merge them. Programmers are involved only in the big architectural decisions, the designs, and in giving feedback to the agents. ...
