Spott application is an Android version of the website. Users can be inspired by their favorite celebrities, actors, characters, etc., and buy things they wear or have. The app also provides the possibility to live sync with TV shows, movies, and series to view articles that appear in the current scene and what they can buy.


This is my own app which helps drivers communicate with and rate other drivers using just a license plate number. I created the Android app using Kotlin, RxJava2, Dagger, Firebase, and MVP.

I also created an API for this app in Ruby on Rails 5 and established an environment on AWS.

This is a mobile app built in React Native for Android and iOS. Patients can send and receive messages to and from doctors to get hints about their health and lifestyle.

Spott is a place where you can inspire yourself with your favorite celebrities, actors, characters, etc. You can check their fashion, accessories, and other things they like. You can then go shopping to buy things you like.

I am a part of the team that creates the page and corresponding CMS, adding new features and constantly improving the layout.

Rugby World Cup 2017

This is an Android and iOS app (both native) helping people stay up to date with RLWC2017 actions. The main screen is a mobile web page. The app is optimized to display the web page and contains some native views (subscribing to teams, selecting notifications, handling notifications).


This project was developed with a group of friends for a German company. The main goal of the project was to create a system for opening door locks produced by the company via Bluetooth Low Energy. I was responsible for:

- Creating an SDK for Android developers who wish to integrate their own door locks.
- Developing the Android app SmartphoneKey. This application allows users to create an account, receive created reservations (also via push) and messages, and open the door locks through the SDK.
- Building an administration console in React.
- Designing BLE firmware in C on Nordic semiconductor hardware.
- Developing a .NET application responsible for communication between a hotel management system and our server.


This service allows people to visit with different doctors through the web, using WebRTC technology. The patient, seeking advice from a specialist, can make an appointment to video chat with the doctor at a date that works for both parties. The doctor can prescribe medicines or give any recommendations to the patient, as well as check to see if they were fulfilled.

Uprising '44

An Android app created for Warsaw Rising Museum. The app integrates with beacons, which were to be placed in the museum, and shows text, video, and image information about Uprising 44. The app references Norman Davies' book "Uprising 44" and contains interview videos with the author. The app wasn't published, but it was a promising piece of software.


Android app similar to YouTube, in which you can see videos from (I also developed the site). The app connects with ChromeCast, allows you to create playlists, add videos to favorites, and more.

iLumio is an entertainment system designed for hotels. I am a member of the team that created the whole system. I worked on the Android app, hotel system integration, and server side.


This Android app allows auditors to control five standards of quality in factories and companies. The auditor can rate each quality factor, take photos, and write notes. When the audit is finished, all information is presented on charts and can be exported to CSV or PDF file formats.

The app is not available for download - the customer distributes it on their own.


This Android app was created with my colleague for a bachelor's degree. It's a game very similar to Monopoly. The game was designed to allow players to play together, each one of his own phone via Bluetooth. Players can also play with a computer player. There is an implemented artificial intelligence mechanism that uses fuzzy logic. The app also provides local game-saving status.
