Selected projects

Samsung Android Store

The Samsung Galaxy Store was the first Hungarian Android store, launched in 2010, before Android Market (Google Play) was available in Hungary. The goal of the store was to offer premium apps to Samsung Galaxy users.

To maximize our reach, we opted for a mobile-first web-based solution. We built the app catalogue and implemented the checkout flow for mobile as well. I was responsible for research, concepting, wireframes and prototyping.

Here are some wireframes from my design documentation:

K&H Bank online banking

K&H Bank is one of the biggest commercial banks in Hungary owned by KBC Bank of Belgium. In 2011, the bank decided to completely overhaul its e-banking system to gain a competitive advantage.

I defined the new feature set, built the information architecture and created the wireframes for the redesign that introduced a wide range of features like bill payments, personal finances, investment management and a sophisticated customer support. I chose to put insights and PFM tools in focus instead of the traditional, unprocessed banking data. Here are two sample wireframes I designed:

The logged-in home: based on my research on what people look for in online banking, I created the homepage that puts the most wanted information and the most useful insights right upfront.

The payments index:


Powerforum is the online trading platform for electricity and gas in Hungary. We helped the organisation to create a new, transparent and efficient way of energy trading.

My task was the complete functional and UX design of the trading system. I conducted interviews with the main traders, created multiple prototypes and refined the UI based on feedback. Since the system was very complex, my specification put a lot of emphasis on technical details (see below).

The project was very successful, Powerforum closed auctions surpassing their expectations and the system is still in use, regularly conducting 9-digit HUF transactions.

Here are some samples from the quite technical system specification I did. The process of an auction:

World Economic Forum

In 2007, we built the Digital Ecosystem community website for the World Economic Forum. The community consisted of high-profile executives, top researchers, analysts and entrepreneurs. The participants exchanged knowledge and ideas around the three future scenarios the World Economic Forum defined.

I was involved from the inception of the digital project, my responsibilities were to conduct research, define the concept, and create the interface prototypes and functional specifications.

The solution we proposed was a web-based community website that offered sharing and collaboration tools that span across different topics and media.

Here’s an excerpt from my concept that started the project:

Here’s a wireframe I later created for the logged-in homepage:

And here’s a diagram from the functional design to define how the search should work:

Zuno Bank

Zuno is the direct banking initiative of Raiffeisen International in Vienna. I was part of the initial 20-person team building a direct bank from scratch and launching it Slovakia.

I was responsible for the UX design of the online bank: I created the concept for the online services, designed the information architecture, built multiple prototypes, and lead usability tests in two countries.

I was also part of the product definition and took part in vendor selection, liaised with the developer, communication, branding companies involved in the project.

Hungarian Telekom

The Hungarian subsidiary of Deutsche Telekom is the biggest telco company in Hungary.

For many years, I worked on the websites and other digital products of T-Home, T-Mobile and T-Systems brands. I worked closely with the web, sales and marketing teams to define the web strategy and action plans for T-Home.

I created wireframes and prototypes for dozens of web-based apps and webpages.


Have a wonderful !
