Crafting interfaces that move, from pixel to prototype to production.

Behind every interface I ship is a system like this one. Pick a style, pull the knobs, and watch every component follow.

I'm Boti, a UI/UX and product designer based in Vienna (Wien), Austria, with 15 years of experience across mobile apps, SaaS products, and embedded interfaces. I've built design systems from scratch, led teams, run design sprints, and shipped work for brands like IKEA, Red Bull, and Wiener Linien.
Three strengths anchor the work: design systems that scale, decisions grounded in how people actually behave, and an AI-assisted workflow that ships more without dropping the quality bar.
What drives me is the space where craft meets code: interfaces that don't just look right but feel right in motion. I'm at my best when I'm part of a team that cares about the details as much as I do.

Every project is different. The process isn't.
01 / 06
Before anything gets designed, I need to know what problem we're actually solving. That means getting close to the business, the users, and the constraints: workshops, stakeholder interviews, and asking the questions nobody thought to ask.
02 / 06
Assumptions are expensive. I use personas, user journey mapping, and usability testing to replace guesswork with real behaviour, watching how people actually use a product before touching Figma.
03 / 06
The research means nothing without synthesis. I look for patterns, contradictions, and gaps: the things that reframe the brief and point toward a sharper solution.
04 / 06
A prototype tells the truth a wireframe can't. I put a working low-fidelity prototype in front of the team on day one, something you click instead of imagine, and sharpen it toward hi-fi from there. Design systems are built in parallel so every decision scales.
05 / 06
Ideas need to be felt, not just seen. I build real, interactive, motion-complete prototypes people react to before a line of production code is written.
06 / 06
A/B tests, analytics, usability sessions. The work doesn't end at handover. I stay involved through implementation and after launch to make sure what shipped actually works.

Joined a Series-A SaaS where the Figma files no longer matched the product and the same component lived three inconsistent ways in the code. I made the case for a real design system, aligned design and engineering on a shared foundation, and rebuilt the app inside it. Then I wired AI into the workflow through MCP so designers draft straight into Figma with system-compliant components, raising speed and consistency across both disciplines.
DungeonFog makes map-making software for tabletop RPGs. As lead designer and producer I wore every hat: the product's UX and UI on one side, the marketing that sold it on the other, from motion and storytelling in the campaigns to the analytics steering them. Designing the tool one day and the campaign for it the next, I carried both the craft and the story to market as the company grew.
dotsandlines is a Vienna creative and branding studio. As Head of UI/UX I built the design team from the ground up, hiring and mentoring juniors into the craft, and stayed accountable for every UI/UX project that left the studio. I brought structure to a brand-led shop, design sprints, lean UX, rapid prototyping, usability testing and accessibility, so the work held up in real use, not just on the page.
allaboutapps is a Vienna mobile app development agency. I designed native mobile apps for a steady run of clients while helping turn a dev-led shop into one that takes design seriously: running workshops, building the team, and pulling UX into projects from the start instead of the end.
As a senior iOS developer at allaboutapps I shipped native apps hands-on, from concept through code, with code reviews, scrum, and a hand in steering the team. The engineering instinct in my design starts here: knowing what's actually buildable, and what motion really costs.
Where it all started. With the iPhone still new, I taught myself Objective-C and began building and shipping iOS apps as a freelancer, right in the early App Store gold rush. Fifteen years on, that beginning still shows: a designer who has always lived close to the code.
I started out chasing the universe, studying astronomy and physics at the University of Vienna. Two fields, one habit: taking enormous, messy systems and breaking them down into something you can actually reason about. I left the telescope for the screen, but the pull never left. The love of deep space, of light earned out of the dark, is the same world this site is built from. Every interface I design still begins with the question the night sky taught me: what is really going on underneath?

The book that made me realize good design is invisible. Norman's thinking on user-centered design still shapes how I approach every interface.

A designer who understands math moves differently. This book cracked open linear algebra and simulation for me, essential for anyone serious about motion and generative design.

Designing for fun is harder than designing for function. Schell's lens on player experience translates directly to how I think about engagement and delight in UI.

I'm open to new opportunities and collaborations. Not available for short-term gigs, but if you're building something worth caring about, let's talk.
