I'm Han, and Rolfdust is the name I design under.
I studied computer engineering, then spent five years designing product interfaces for logistics, AI tooling and fintech. For the past six months I've been designing for games, where the problem is the same but faster: a player has about a second to read the screen.

- Looking forA UI/UX design role
Most of that was complex B2B software: warehouse tools people had to learn in a morning, and crypto screens where a wrong click can't be undone. It turned out to be good training for game UI. A HUD has the same job, with less time to do it.
Alongside client work I've redesigned a published mobile puzzle game and built three game concepts of my own: Button Up, Nimbo and Hoplo. Each has a logo, a component kit with every state, and assets an engineer can use as they are. The engineering degree helps here, because I know what a developer needs from a handoff.
Outside work I read about behavioural psychology and etymology, keep up with human-centred AI, make a lot of coffee, and read world literature.
What I'm good at
- Pillar1,2801,2901,310Perfect
HUDs you read without looking
The score, the progress and the reward sit where the eye already is, so the player never has to stop playing to read the screen.
- PlayRestPressedLocked
Every state, designed
Each component ships with its rest, pressed and locked states, so a new screen is assembled from parts instead of drawn from scratch.
The loop before the screens
I map home, play, fail and retry first, so every screen knows what comes before it and after it. That habit comes from five years of product UX.
- +2 slots·1 left0 leftWatch adUsed this level
Rewards with a cap
Shops, offers and rewarded ads each get their limit written next to them, so the ad never becomes the strategy.
- Next levelCaps fixed · middle stretches
Built for handoff
Assets are exported as 9-slice pieces with their insets, so an engineer can stretch a button to any label without warping its rim.
- Colour onlyColour + shape
Readable by more players
A shape beside every colour, contrast checked at the smallest size, and icons where words would slow you down. Accessibility is part of the kit, not a later pass.
