B-all One is the first publicly available game on Magic Leap One that was entirely developed in Lumin SDK (C++).

The game lets you play with a virtual racquet and ball in your room. The digital ball bounces off the real obstacles giving the impression of playing with a real ball.

The project was demanding due to the early version of the software and hardware components which did not always work as expected.

Collectomate is a platform that provides software and hardware solutions that makes it easier for couriers to deliver and for recipients to pick up parcels.

My responsibility was to create a cross-platform (React Native, iOS, Android) mobile application which notifies the recipients about the delivery of the package and helps them to locate the package, indicating the appropriate locker. Additionally, there was a second application which was installed on the tablet embedded in the Collectomate unit.

The tablet app is used by couriers and office staff to deliver the packages and maintain the unit.

This is an open source 360° video player made for iOS (Swift, OpenGL). Each frame of the 360° video is mapped onto a sphere giving the impression that the viewer is in the middle of the action.

Creatubbles is a social platform for children, teachers, and parents. The service allows children to share their work (creations) with other children around the world.

My role was to develop and maintain the code of iOS app (Obj-C and Swift), conduct code reviews, and write unit tests and UI tests.

It was a challenging project in terms of effective communication because almost every team member came from a different country.

I contributed to a big project that was designed for the web, iOS, and Android. When I joined the team, I came across a legacy code that was unstable and inefficient. The nickname of the project was "Broken Window" because it was too advanced to start over, but it was also in too bad of condition for on-time delivery.

Together with the team, we developed a strategy that enabled us to deliver a stable product with only a slight delay. In this project, I learned a lot about the importance of being transparent, effective communication and efficient cooperation of the whole team.

Marley Spoon allows users to order ingredients and recipes making it easy to cook meals at home.

I was the delivery leader of a two-person team that was to deliver the MVP version to the customer. Because the client was perfectly prepared and came to us with all the well-thought-out requirements, we managed to complete the MVP on time and without any unexpected problems (iOS, Objective-C).

I was responsible for developing and maintaining an iOS application that is used to download, organize, and view files on iPhone and iPad. The application integrates external storage services such as Dropbox, Google Drive, Box.com, OneDrive. It supports opening large images, listening to sound files, previewing presentations, remote document printing, and more.

FlipCards is an iOS application designed to enhance the process of memory training and learning foreign languages. It is a visualization of the popular flashcard learning system.

This was my very first iOS project that was released to the App Store. It was featured by Apple for its graphics and educational style. The app was also mentioned in the Washington Post in 2012.

As a private personal project, I designed and implemented a wallpaper with a map of the world that covers a wall with the measurements of 3m x 2.6m.

The map was made from 16,000 small tiles of images fetched from Google Maps API (macOS, Objective-C). The tiles were merged into three big images (+2 GB) and were printed off on the HP DesignJet L26500. The map is currently hanging on a wall in my room.

In the course of my career, I developed a number of applications and games in high school and college (2001-2006).

Projects:
• World Engine (C++, OpenGL): a game engine that shows my use of algorithms for space partitioning (Octree, BSP Tree, portals)
• Fluid Motion (C++, DirectX, HLSL): a simulation of water droplets flowing down on different surfaces; all of the computations were made on GPU
• Number plate recognition app (C#, WinForms)
• Graphs and fractals (Turbo Pascal): an application that won the national IT competition in the DOS category
• Multiple games in OpenGL: 3D Billiards, Moonlander, Battle Tanks, and more
• Reversi (Java): a popular board game
• Wolf (C): a clone of the popular game Wolfenstein
