Hej, I’m Matilda Andersson Carlsten
Stockholm — 10+ years creating better experiences.
01
Open finance infrastructure. A category with no conventions, so we wrote them. We pioneered the practice in new markets and showed the way for our customers, all while leading and developing a growing team and organisation.
02
Onboarding and activation. KYC, KYB and AML for a Luxembourg banking licence across 11 markets, and the PayPal account integration for millions of merchants.
“How iZettle helps create ‘flow’.”Built for Mars, 2020 — one of two flows singled out against Square, SumUp and Verifone
03
A savings platform for complete beginners and advanced traders at once, off a legacy system. Then MiFID II across 10+ consumer products.
04
First MVP with the CPO, practice established, and I hired my own replacement before I left.
05
Four years dropped into critical, time-sensitive projects — useful before I properly understood the organisation.
06
Brand identity and UI for a loan product launch. Now one of OPR’s most profitable products.
07
Brand strategy for Azure, Visual Studio and Xamarin, and the campaigns that reached developers.
There isn’t one. Every project ran differently; what stays constant is the loop, and knowing how much of each part the situation can carry.
More technical than many designers, and deliberately so. I go into the repos rather than design on top of a guess — better collaboration with developers, and I can ship my own work. I know my way around designing for tech-heavy products.
I build clickable prototypes instead of mockups while perfecting the practice around them: what’s worth building this way, how it gets reviewed, where it quietly goes wrong. AI has made loops shorter while removing abstractions and boosting creativity.
Mature markets, instrumented funnels, small hard-won gains. I work out what a number should be before designing against it — and write up the experiments that lose as carefully as the ones that win.
Most of this was built under client contract or sits behind a login, and plenty has been redesigned since. Rather than show screens I don’t own, I hope you’ll give me the chance to explain it face to face — because who doesn’t like a cup of coffee and talking to another human being better than scrolling yet another webpage?
