Hi, my name is Krzysztof Rusnarczyk and I make usable interfaces & better web experiences.

Krzysztof Rusnarczyk

Underovsky is an artisanal UI studio based in Krakow; it's owned and operated by me, Krzysztof Rusnarczyk.

It's a one-man operation, which means each of my clients gets my full attention (it also means I get to run a really tight ship).

I have over 7 years of experience in both designing and implementing user interfaces. I have a background in both development and design, giving me a pretty unique perspective, and letting me adopt a big-picture approach. I've also lead teams of people and worked as a CTO; thanks to that, I have insight in how to run an organization — or its tech department — in a way that really works for its business goals.

As you can see, I juggle quite a lot of things. In practical terms, I can handle full stack web services as well as interfaces, design your user interface just as well as I can implement it, and I do it all from an angle that merges UX and UI — all the while paying close attention to details.

To quote Charles Eames:

The details are not the details. They make the design.

And to paraphrase that a bit: They also make the code.

For a more in-depth look at what I can do for you, check out my services.

Some of the things I've worked on include:

  • implementing a hybrid mobile app for Aegon (used by sales reps during client meetings),
  • implementing a dedicated CMS for web-based marketing and sales campaigns for James Cook Media,
  • designing the interfaces of 3 distinct systems for the Krakow University of Science and Technology,
  • implementing the interface of a web app for language tutors.

Among the companies I've done work for are Aegon, Getin Bank, NAD Electronics, PMR, the Krakow University of Science and Technology, InTuition Languages, Next Generation.

I work with new technology companies, startups, and web service companies.

And I like to devote some of my time to contribute to free software and the open-source community. Seriously, just ask me about it — but prepare for a lengthy conversation when you do.

Underovsky and nature

Over time, my philosophy has crystallized into my current approach: simple doesn't mean simplistic, or insufficient. In this day and age, simple is a feature: it lets you direct your viewers, customers, readers to where you want them to go, and at the same time it doesn't require effort of them.

Simple is elegant. Simple is effective. And I don't know about you, but elegant and effective are two of the most important among the things I strive for and deliver.

Apart from that, I am a die-hard perfectionist, so unless you want your project to be top-quality all around, we might not get along that well.

A bit of historical trivia: I started out working on movie edits and motion design. But, luckily for you and me, I realized I'm much better at user experience design.


In the meantime, I try to keep my mind and body in shape; I cut my teeth (not literally, although there were some close calls) on some very dynamic rollerblading, and I still play soccer on a regular basis; and I find food for thought, peace, and often inspiration in my long list of books to read, my equally long forest hikes, and through meditation and mindfulness.

Oh, and I will argue hard that Bob Ross was putting out some of the most amazing art this side of William Turner.
