2012 · My first Chrome extension. Double click on the page's corners to instantly scroll to the top or bottom. No UI, no extra buttons, no settings. Inspired by 37 signals & Basecamp.

I wrote an article about a few things I've learned in this project.


At peaks the extension exceeds 25k views and 40+ installations per day

Public Transport Prague

Preview iPhone Preview Apple watch

2015 · An iOS app that shows departure times for all lines from nearest stops from user's current location. No input is required and therefore no control interfaces. Data are in GTFS format, which is standard in many metropoles and the app will function as-is also in other cities e.g. Berlin, NY, London etc. Works both on iPhone and Apple watch.

2010‚Äď2013 ¬∑ O2 is the biggest telco provider in Czech republic. In a couple of projects we redesigned the company's main web www.o2.cz (consisting of several thousands pages), e-shop and self-service portal (My O2). All this was done using minimal resources and without need of deprioritizing company's other core projects. We introduced responsive designprinciples, design stencils and a modular framework for cost-cutting of content creation, which is still being used in the company. Design decisions were based on analytics, user tests and data-driven conclusions from hundreds of A/B tests.
