Software Developer in Warszawa, Poland

For this project, I created this Android game mainly for the purpose of learning and gaining experience in preparing, deploying to a store, and maintaining an application. The application was installed on 30,000 devices and brought revenue from advertisements.

This is an open-source library that I've created with a custom view for Android applications. It's a highly customizable view with animations that can indicate the percentage progress of some action.

I wrote this Android application for fun as a private project. It acts as a private digital diary. Every ten minutes, it also automatically checks the background phone's location and saves it to an internal database for processing and discovering interesting patterns in a user's behavior such as commonly visited places, traveling paths, and the latest visit to a particular place.

I developed this utility/hack Android app for Clash of Clans, a very popular mobile game. So far my app has been installed on more than 350,000 devices in the world.

I developed this data-mining project for my master's thesis. I used some clustering algorithms along with many data mining techniques to find places where a user of a phone spends most of the time based on hundreds of thousands of location logs collected by a smartphone.

This is a data-mining project for my bachelor's thesis aimed to classify home websites as a university or scholar's homepage.
