Hi, I’m Diogo. I’m the dad of two incredible girls and a product engineer, based in Cambridge, UK.
This page is inspired by my recent trip to Spain, where I saw my first total eclipse. Hands-down the most beautiful natural phenomenon I have ever experienced! I wanted to convey that feeling when building this page. A sense of awe and optimism, with an occasional pinch of anemoia and nostalgia.
I hope you enjoy my content. Oh, it’s better with sound on if you can (and scroll around).
I’m trying to figure out life, including what comes next for those who make software and how humans and machines can work together.
You can explore my raw thoughts in my digital garden, or my more polished articles on Substack.
That’s where I share what I’m building, learning, and trying to make sense of. I write about building products, games and experiences, AI, and how they fit into our lives: what these tools let us do, what we still want to do ourselves, and when to disconnect.
I learn by building: a prototype to test an idea, a tool to solve a problem, or an experiment to explore something new. Writing helps me think it through, whether that becomes a longer piece or just a brief thought worth sharing. I like understanding what’s new, but I tend to spend more time on directions I believe have a future. I’m sharing what I learn in the hope that some of it helps someone else.
I rotate between different obsessions, so a few of those will probably show up in my writing too. I also make YouTube videos (I’d like to do more, but they take more time than I have for them right now).
My mind tends to race, but I’d like this to be a calm place to think things through.
How I got here
I’m currently a product engineer at Airspeed. Before that, I worked at Apple in AIML, on data and annotation tools supporting on-device Siri and its future development.
Earlier in my career, I started my own games studio before joining Sony PlayStation. At PlayStation, I worked on LittleBigPlanet PSP, Killzone Mercenary, and in a group exploring new game concepts. LittleBigPlanet PSP won a BAFTA for Best Handheld Game. I still have a signed copy of the game that I’m very proud of.
I’ve also worked on connectivity software at Icomera and a new music experience at LOST, mixing human and machine curation.
Each move has meant learning a different field. That mix of experiences is part of what I bring to the things I build and write about here.
What I use
I (mostly) think on paper. There’s usually a notebook with me: currently Field Notes and Leuchtturm1917 A5 (Soft), though I like trying new ones. I use an OHTO GS02 pen, and sometimes a GraphGear 1000 pencil with 2B lead.
Obsidian is my digital memory, more like a database, though I sometimes prefer to think by typing rather than on paper. I’ve built my own agent integration on Obsidian. The Things app holds the tasks that just need to happen and that I’d otherwise forget.
For development, I use a MacBook Pro with an M4 Pro chip and Claude Code. This setup changes often, as I keep experimenting with new tools.
And if you’d rather explore than read an introduction, my mind is playable.
