London, UK · Lisbon, Portugal · Constantly building, even if it's something small
Hi. I'm Tiago.
Six apps. Forty countries.
A thousand slow miles.
One moustache.
Drag the line
Solo builder
Aviation by day, small software products by night, and running slowly somewhere in between — far enough into it now that other people ask me how to start, which makes me a coach in everything but the certificate. A family man for all the hours that are left, and those are the good ones. This is the side of the internet where I'm allowed to be less formal about it.
Two doors
Things I made.
Things I'd wear.
One is a shelf of software. One is a rail of cotton.

asked me to build.
Six web apps and one YouTube channel
Say hello
Found something
you want to talk about?
I answer most emails, eventually, usually after a run.
Gallery
Six apps. Nobody asked.
Product, code, infrastructure, pricing page and all. Built alone, in evenings, on the same small stack every time. Three of them are live businesses; the rest are mine alone. Hover to stop the carousel.

Things I'd
actually wear.
Shop
Small shop. Big opinions.
Nothing here is on sale yet — this is the shopfront, not the till. There is no sign-up form and no mailing list: Notify me opens an email, already written, that you can send or close. I reply when the first run is printed, and that is the end of it.
First run
Merch.
06 pieces · printed in the UK
The honest bit
Why merch at all?
Everything else I make lives on a screen and disappears the moment somebody closes the tab. A printed thing sits in a drawer, gets worn thin, gets packed for a trip. I wanted a few objects that survive that way.
This first run is drawn from what I actually do — running, aviation, the two cities I keep flying between, and one moustache. When the range changes, this paragraph changes with it.
About
Forty countries. One moustache.
I grew up Portuguese and now live in London, which is a sentence hiding about four moves. Along the way I have lived in Jeddah, Tunis and Auckland — three cities that share almost nothing except that aviation is what took me to each of them, and in all of them I arrived knowing nobody.
Forty-odd countries later, I have stopped believing in the phrase "global product" unless somebody can tell me which forty. That is roughly what I do for a living too: commercial aviation, senior product marketing and product strategy, and a great deal of turning what a company says to itself into something a customer would actually recognise.
In whatever time is left over I build small software products on my own, and run — slowly, often, and with more enthusiasm than talent. Neither pays for itself yet. Both are the part of the week I look forward to.
I look up a lot. NASA got me first, SpaceX got me again twenty years later, and somewhere in between a widebody taught me that engineering can be beautiful without ever saying so.
Route flown
Places that
stuck.
Plus roughly 0 countries visited, and a hard-won habit of packing far too little.
The fleet I'd fly
Three aircraft,
no arguments.
The one that made long-haul quiet. Carbon fibre, big windows, and a cabin altitude that means you land like a person rather than a parcel.
The workhorse. Tens of millions of flights of collective muscle memory. Unglamorous, everywhere, and quietly the most important aeroplane of my working life.
Two engines, no arguments. Still the most convincing case ever made for doing more with less.
Unsorted
Things I like,
in no order.
Logbook
Off the clock.
Independent software · six and counting
Designing, building and shipping small products on my own. The whole shelf is in /gallery.
Family first, camera second
Most of the weekend belongs to the people I live with, which is the right order and took me a while to get to. What is left goes into a YouTube channel about running badly and improving anyway. Sign-off, every episode: "Go out. No matter what."
Running & walking
Half marathons at a pace nobody would call quick, and long walks whenever the weather allows it. The 1:30 is still out there somewhere.
Whatever is half-built
There is always one in progress. Right now it is Sereno, with Solar queued behind it. The finished ones are in the gallery; this is the one that keeps me up.
Final approach
Still here?
Say something.

01Who you are dealing with
This website is run by Tiago d’Aubigné as an individual, from the United Kingdom. It is a personal site: a record of software I build in my own time, a shop for a small run of merchandise, and some writing about running and travel. It is not operated by, on behalf of, or in association with any employer of mine, and nothing on it should be read as the position of any company.
02Using the site
You are welcome to read, link to and quote this site. You may not copy it wholesale, pass its content off as your own, scrape it at a volume that costs me money, or use it to build a page that pretends to be me.
The site is provided as it is. I try to keep it accurate and available, but I make no promise that it will be either. I may change or remove anything on it at any time without notice.
03The shop
The shop is a shopfront, not a till. At the time of writing nothing on it is for sale: no order can be placed, no payment can be taken, and no contract of sale can be formed. Prices shown are an indication of what the pieces are likely to cost, not an offer.
When the shop starts trading, payments will be handled by Stripe and these terms will be extended to cover ordering, delivery, cancellation and returns, including your statutory right to cancel a distance purchase under the Consumer Contracts Regulations 2013. Nothing in this section limits those rights once they apply.
04The waiting list
If you email me to be told when the first run is printed, I will keep your address for that purpose and no other. Ask me to remove it and I will. The privacy notice has the detail.
05What belongs to whom
The design, words, drawings and code on this site are mine, unless credited otherwise. The software products shown in the gallery, and their names and logos, are also mine. Product names belonging to other people — Airbus, Boeing, Cloudflare, Stripe, Google and anyone else mentioned — belong to them, and appear here only to describe things factually.
The technical drawings on this site are studies made for illustration. They are not engineering documents and must not be relied on as such.
06Links out
Where this site links somewhere else, that somewhere else is not mine and I am not responsible for it.
07Liability
To the extent the law allows, I am not liable for any loss arising from your use of this site or anything you take from it. Nothing here excludes liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot lawfully be excluded.
08Law
These terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction. If you are a consumer resident elsewhere in the UK, you keep the protection of your local law.
09Changes
I may update these terms. The date at the top tells you when they last changed.

The privacy
notice.
Shorter than this one, and considerably duller.
Legal
Privacy notice.
Last updated 2026 · tiagodaubigne.com
01The short version
This site sets no cookies and has no advertising, tracking pixels or social plug-ins. It does count visits, using Sereno — a cookieless analytics tool I built myself and run on my own infrastructure. It records that a page was viewed, not who viewed it. No profile of you is built, nothing follows you to another website, and no data reaches a third party. If you email me, I have your email.
02Who is responsible
Tiago d’Aubigné, an individual in the United Kingdom, is the data controller for this site. Contact: .
03What is actually collected
- Server logs. The site is served through a hosting provider that records the usual technical detail of a request — IP address, rough location, browser and referring page — for security and to keep the site up. I do not use these to build a profile of you, and I do not join them to anything else.
- Email. If you write to me, your address and whatever you wrote sit in my mailbox until I clear it out. Nothing else is done with them.
- The waiting list. If you ask to be told when the shop opens, I keep your address for exactly that. No newsletter, no sharing, no selling.
- Visit counts. Sereno records that a page was loaded, along with the referring site, rough country, and whether you are on a phone or a desktop. It sets nothing on your device, issues no identifier, and cannot recognise you on a return visit or anywhere else. It is my own product, running on my own Cloudflare account — measuring this site is also how I test it.
- Your browser’s own memory. The site remembers whether you chose light or dark. That preference stays in your browser and never reaches me.
04The requests that leave this site
Being straight about this matters more than the line on the footer. Three things on this page reach outside it:
- Typefaces load from Google Fonts, so your browser makes a request to Google and Google sees your IP address. No cookie is set by it.
- Weather for the small turbulence indicator comes from a public forecast service, requested with fixed coordinates for London — not yours. No identifier of any kind is sent, and if the request fails the indicator carries on with a default.
- Sereno receives the page view described above. It is mine, so nothing is being handed to anyone else, but it is still a request leaving your browser and you should know it happens. A tracker blocker will stop it, and the site works exactly the same without it.
05Why I am allowed to hold any of it
Server logs and visit counts: my legitimate interest in a site that stays up, is not attacked, and that I can tell is being read at all. Because nothing is stored on your device and no identifier is issued, this counting does not require a consent banner — which is the entire reason I built it that way. Email and the waiting list: your consent, given by writing to me, withdrawable at any time by writing to me again.
06How long
Logs are kept briefly by the host and then discarded. Email is kept while the conversation is still useful. The waiting list is deleted once the first run has shipped and everyone on it has been told, or sooner if you ask.
07Who else sees it
The hosting provider and my email provider, because they have to. Nobody else. Nothing is sold, and there is no automated decision-making or profiling of any kind.
08Your rights
Under UK data protection law you can ask me for a copy of what I hold about you, ask me to correct it, ask me to delete it, or object to my holding it. Email me and I will do it. If you think I have handled it badly you can complain to the Information Commissioner’s Office at ico.org.uk.
09Children
This site is not aimed at children and I do not knowingly collect anything from them.
10Changes
If any of this changes — and it will when the shop starts taking payments — the date at the top will change with it.
