A fantasy RPG game for children developed in Unity that got a prestigious Nintendo Switch promotion.

I built the game from the ground up based on the client's growth-driven design (or GDD) and even incorporated some of my own ideas, which the client loved. I designed and implemented custom systems for battles, character development, customization, shops, and upgrades. Additionally, I created custom tools to enhance efficiency in future development efforts.

A mobile app used by thousands of dental and medical students. This app provided a platform for students to learn, memorize, and engage with their curriculum through simulated environments and augmented reality (AR) experiences. My particular focus within this project revolved around the suturing aspect, where the students learned different types of sutures and could see the wound closely based on their suturing patterns.

A fast hyper-casual car game where the player drives an electric car and needs to destroy all diesel cars and drive to the finish line. The player drives forward in three lines, needs to avoid explosive cars, drive through gates, gain nitro, and smash diesel cars to get a higher score. There are many new cars with new abilities to be bought for coins. There is monetization implemented including "Last Save" playable ad and "No Ads" in-app purchase.

A virtual reality app that teaches its users to replace an engine head. It is developed to have three stages: disassembly of the engine head, replacement of some of its parts, and a final quiz. The user is guided through the whole process by arrows. The process seems real; there are real models, beautiful graphics, haptic feedback on the controllers, and more.

This software guides its user through a pipe pressure inspection in augmented reality. It is run on a handheld device. The app recognizes the pipes in front of the camera and shows the user where the fluids flow in them. It then guides the user on how to perform an inspection. When the user sees something broken, they can tap on the screen where the issue is. This saves a photo of the problem. The user can then record a voice message describing the problem and save all this information to the database.

A 2D Unity game imitating the old and popular game Ugh! from 1992, except for that it takes place in space. You fly a space rocket and need to take passengers from one platform to another. During the flight you collect coins, fuel and health which help you finish the level. You also avoid getting hit by a UFO or crashing into surroundings.
Then you get to a Hangar. There you can buy and upgrade various spaceships, each having different properties, and go with them to another space adventure!

This app was developed for a castle in Slovakia. It lets you scan the code of a knight and displays him in the real world through augmented reality. The knight is standing on the ground in a cool pose and is real-size. You can then take a photo of him or even of your friend standing next to him and share this photo on any social media.

An augmented reality app developed for a Slovakian castle. You can point the camera of your phone at one of their paintings and see it become live. It starts moving and a nice animation starts playing. You can also hear the voices of people, sounds of nature and more from the moving picture.
