A bout me
I am a passionate Unity Game Developer with extensive hands-on experience in building both commercial
and non-commercial games.

Before tackling a complex task, I conduct research to review how others have implemented similar solutions,
in order to explore different approaches and select the most optimal one.

I enjoy exploring different approaches and technologies, as well as learning from others. This curiosity drives
me to continuously expand my skill set and apply the best practices from various sources, ensuring that I
stay on the cutting edge and contribute effectively to every project I work on.

S ome of the projects I worked on at my previous company
Due to the NDA I`m allowed to share links only to projects I worked on from the very beginning
and that have already been released in online stores.

Junkyard Garage Simulator

https://www.youtube.com/watch?v=ClKVrRZX6tE4

I worked on a vehicle restoration and customization project built around repairing
damaged cars, improving their condition, and turning them into fully restored, visually
upgraded vehicles. The gameplay combined hands-on garage interaction, restoration
systems, and progression driven by vehicle transformation from scrapyard state to
final presentation.

So me implemented features:
Vehicle restoration and repair work flow

Car customization and visual upgrade system

Garage interaction and task progression system

UI flow for workshop, repair, and customization

features

Vehicle condition and transformation pipeline

The most challenging task was implementing the full restoration
pipeline, because a single vehicle had to move through multiple
gameplay and visual states consistently — from damaged and
rusted condition to repaired, customized, and presentation-ready
form — while keeping all systems synchronized and predictable for
the player.

Tune My Car 2025 (PS4, Nintendo version coming soon)

https://www.youtube.com/watch?v=pTrZUXClrDk&t=2s

I worked on this project together with a Game Designer, several 3D Artists, and a UI/UX
Designer. My responsibilities included implementing the technical part of the project
described in the Game Design Document, creating UI and all animations in the game.

So me implemented features:
U I interaction and animation system

Car upgrade and vehicle stats system

Player test drive system

Object interaction system

The most challenging task was implementing the auto preview
rendering system, which dynamically redraws the car preview
image for all menus after visual modifications (such as repainting,
part replacement, or rust removal).

S ome Other Projects I`ve worked on
During my work, I also performed remasters of several older company titles. I can’t
share the names or links due to NDA, but I can describe my role and responsibilities.

O ne of the most challenging projects was a farming simulator where players
transported goods across a large map, sowed fields with different crops, plowed

the land, harvested, sold produce, and unlocked new machinery to improve efficiency.

My responsibilities included reworking the UI system, adding animations and sound
effects, fixing gameplay and save-system bugs (for example, a bug where tractors
collided rear-first and flew into the air), and improving the overall player experience
(such as adjusting vehicle controllers for more responsive handling).

Another project was a firefighter simulator in which players took on the role of

a firefighter extinguishing fires throughout a city. My tasks included fixing numerous
bugs caused by outdated assets, correcting occlusion-culling issues, resolving crash
causes on the PS4 platform, configuring traffic-system assets, creating and integrating
a playable tutorial system, and performing deep optimization to achieve stable
framerate performance.
