My life revolves around the internet. And I design (& sometimes build) things for it.
Right now, I'm based in London. When I'm not there, you'd most likely find me either on trams in Amsterdam, on the U-bahn in Berlin, driving across Morocco, stuck in Lagos traffic, or planning new trips on Notion (Where I mostly plan my life).
I'm at my best when solving unstructured problems by creating systems that solve them at scale. I've spent the last 9 years doing this within large design teams embedded in organizations, as part of smaller teams, or as a solo designer at startups.
At the moment, I'm a senior product designer at Stripe where I focus primarily on Tax.
I'm deeply fascinated by money and financial systems - Its fictional nature, how it moves, how it's made, how it grows, how it's invested, and how it's created. Because of this, I've spent the last 5 years designing financial software.
What I'm really good at?
- Interface design
- Experience design
- User research
- Product strategy
- Finding the best memes (I consider this a life skill)

What I want to do next
There’s a moment in a designer’s career when the centre of gravity shifts. Early on, the work is vertical. You focus on a feature, a flow, a specific screen. Success looks like shipping something self-contained and polished. But eventually you start seeing past individual pages. You notice the connective tissue. You realise the real work — the work that makes products feel inevitable — happens horizontally.
Horizontal systems work lives in the layers users don’t consciously register: the surfaces and the patterns that quietly set expectations. It’s the logic of spacing, the rhythm of typography, the weight of icons, the structure of navigation, the behaviours that repeat and accumulate until they become a product’s signature. It’s not one screen but the consistency between fifty of them. It’s not the shine of a new feature but the feeling that every part of the product speaks the same language.
This type of work asks a different question: not What is the solution? but What is the underlying system? You start designing rules, not just outcomes. You think in patterns, not pages. You build surfaces that act like foundations — platforms for features you haven’t even imagined yet. It’s slower, deeper, more strategic. It demands taste, restraint, and a willingness to solve problems that no one else can name but everyone else feels.
And when it’s done well, it becomes invisible. Users don’t thank you for coherent spacing or a predictable drawer behaviour. But they move faster. They trust the product. They feel the craft without having to look for it.
This is the kind of work I want to do next.
Outside of work?
I wear multiple hats and have a lot of hobbies - Sometimes an engineer, other times a PM for side projects, and increasingly a mixologist, painter, photographer, and filmmaker.
Travel, Photography & Filmmaking
I currently own a Fujifilm X100V (that I'm always with and take along with me when I travel). You'll typically find some of those photos I take on sesan.photos
This site.
It will always evolve. The idea is to create a little corner on the internet for my work, thoughts, life and interests.
