About me

I focus on crafting interfaces and outstanding experiences for all digital devices, carefully balancing between user needs, business goals and technical feasibility. Being a digital product designer with experience in front-end development and project management makes a unique skill set.

Currently, I work for one of the top international media companies in Scandinavia. Previously, I had been working for five years for one of the biggest media companies in Poland. Earlier on while studying I was also freelancing for five years mostly for small businesses doing all kinds of stuff web-related. In my free time, I take photos, fly my drone, read books, travel and learn how to edit and produce movies.

I strive for an agile and highly iterative design process, that results in products having a real impact.

I worked with

UI design and development

It all begun when I started using the Internet — this absolutely brilliant idea — in 1997. I even remember the time when there was no Google :). I also fell in love with graphic design and I was taking my first steps in Adobe Photoshop in 2002. Being fascinated by the new technology and visual creation it was only natural to pursue a career as a digital product designer.

I pay close attention to details — typography, colours, contrast, layout, grids — all that constitutes a general sense of aesthetics and beauty. An iterative design process that includes accepting and managing feedback is of great importance to me. I used to develop websites from scratch so I have a deep understanding of how the programmers work and what they need. Having completed multiple projects I have an ability to independently drive product design.

Mobile apps and responsive web design

In recent years we’ve been witnessing the surge in all kinds of tech devices: smartphones, tablets, smartwatches and smart TVs. The importance of responsive web design is nowadays really obvious.

I have experience in designing native mobile apps for both iOS and Android operating systems. I’m familiar with the specific design guidelines, patterns, and libraries.

User experience design

I have expertise in developing information architecture, interaction models, user flows, performing market analysis, managing usability testing, drawing conclusions from customer feedback, site metrics, and usability findings. I have been using many useful tools for creating wireframes, functional prototypes, and usability tests like Hotjar, UXPin, Sketch, Adobe XD, Axure, InVision among others.

I strongly believe in importance of comprehensive involvement, holistic approach and team collaboration when working on defining requirements, conceptual development, all the way to the final product.

Marketing and project management

Having academic background in marketing and business management I thoroughly understand the importance of business strategy and the complexity of needs of every stakeholder.

I was working integrally on creating mobile apps, including managing the projects, preparing functional specifications, art directing and scheduling. I have a basic experience in web and mobile app analytics systems, defining metrics, KPIs, and optimizing performance. I developed both B2B and B2C applications.
