I've been writing software since the last millennium, and I've watched our industry reinvent itself several times: the arrival of the internet, the dotcom bubble and its bursting, cloud computing, mobile, the way open source changed how all software gets built, and now AI. I've spent my career adopting each of these waves instead of resisting them.
At heart I'm a technologist. I love code, well-crafted software, and the steady stream of invention this field produces. But the lesson that has held up across every one of those transformations is a humble one: most of the wins come from actually trying things. The best line of code is the one you don't have to write. Often the smartest way to get something done is a whiteboard and a coffee, not a clever solution.
I learned that the hard way. I founded Spotify's Site Reliability Engineering team and grew it from 5 people to over 100, moved more than 15,000 servers to Google Cloud, and helped get the stack ready for the IPO. Before that I founded an internet provider and ran it for seven years. Today I run All Tuner Labs, a small, lean lab where I help others put hard-learned lessons to work and build useful products for the future.
This newsletter is where I think out loud about building and running software. Some of it is about AI and how it's actually changing the job, not just the demos. A lot of it isn't: scaling teams and systems, the infrastructure we've quietly come to lean on too hard, developer tooling, the craft of well-made software, and the gap between what's new and what genuinely works. I write for people who build things and have to live with the results.
Everything I publish lives first on my blog; this newsletter is the email edition. I also write in Catalan, on my Catalan blog and in the Catalan newsletter.
