More updated than ever. 2020s engineering leaders must be more into the details. That’s a feature and not a bug.
“Servant leadership” (misapplied) created a lot of peace time engineering leaders.

"538 microservices? What a mess."
Four years ago, I wrote Disasters I've Seen in a Microservices World. I thought by now we'd have solved most of them.
We didn't. We just learned to live with the chaos. Link below 👇

I've written a sequel to "Disasters I've Seen in a Microservices World," my most-read blog post. Ten disasters later, it's still chaotic, and with the rise of AI agents, it's bound to get worse. Planning to publish soon. Anyone want to read it before I do?

Everyone talks about multi-cloud and reliability. Here’s what it looked like in practice when I joined Adevinta five years ago. The company had just agreed to acquire the eBay Classifieds Group, its secondhand marketplaces division. On the table: private cloud, GCP, and AWS.

.@karpathy says the best way to learn is to build things.
He’s right, but as engineers, we know that’s only half the story.
Writing, teaching, or preparing a talk forces you to understand what you have built.

LLMs changed everything for me. I got my first money on @hirotahog, thanks to it. Before I had lots of ideas but with my limited time, I threw the towel before I went live. Now I go from idea to prod quickly and I try a lot of stuff. FAFO

2025 is my "back to blogging" year! After 1.5 years of hiatus, I've written eight blog posts this year. The fun part for me? Talking about SaaS, Private Equity, being a Head of Eng, and more.

I wrote a post, after @factorialapp's latest announcement: back in the office, five days a week 🔥 Remote is a tool, not dogma. Why? Juniors struggle, culture slips. Hybrid needs rules; remote edges, small teams. Tradeoffs. Full post below

One of the comments I received in HN was this one. My post aimed at sharing my personal experience and not work-wise. Still, there are a lot of things to unpack.

I also learned how to "ping-pong" with ChatGPT in terms of producing good PRDs and identifying areas where there are weak spots, such as tests.

I’ve spent three years "vibe coding" with LLMs. Shipping side projects I’d never have had time to build otherwise. In terms of implementation, I agree with @iagolast and I don't feel it's "magic" anymore, but I do feel a lot more productive. Full post below.

🚩"Not a 9-5 job" in a job post: is it a red flag? Some roles, such as those at OpenAI or Anthropic, require extra hours but offer career growth, equity, or a mission-driven impact. Effort can be a choice, not a trap, if the upside’s real. Read more: bit.ly/3HIJKlw

One of Slack’s major moats is to have access to a stream of conversations in a business. AI and LLMs that build atop these and generate meaningful summaries, documentation, etc are a big threat to their business. Alas, new rate limits.

Typed languages, CD, writing culture? Still worth it.
Scala? Test pyramids? Preprod parity? Not so much.
New lessons? Support, momentum, brag docs.

What happens after a private equity takeover? Many things. The playbook is quite consistent. One of the main parts is replacing leadership with people more experienced or aligned with PE interests.

The MVP is live! Built a simple UI to assign tasks and track who’s up next for all-hands or newsletters. The fairness algorithm is in progress to stop the “always me” vibe. It’s rough, but it’s something. Any feedback?

Three years ago, I suggested we trade off a mid/senior-level engineer for someone out of college. It was the best call I ever made. Today, we're equally sad this engineer is leaving the team and super excited because he'll join a top-notch AI company. Hire junior folks.

The last point is where you can shine as a manager, after all the hard work before, setting the tone and culture for further promotions. Make the reasons for promotion public, and start a virtuous circle. What's your experience with promotions?

The last point is where you can shine as a manager, after all the hard work before, setting the tone and culture for further promotions. Make the reasons for promotion public, and start a virtuous circle. What's your experience with promotions?
There are four points:
1. It starts with YOU. Vouch for promoting people for different reasons. Easy one.
2. Engage early on with your peers to get their support
3. Prepare for the calibration committees
4. ‼️ Make the reasons for promotion public. This is the game changer
