Gameplay systems. Graphics. Optimization.
I build gameplay systems in C#, graphics in URP and tools for Unity. I develop my own games independently and bring code, graphics and content together in a team.

Build a defense. Hold the line.
A first-person defense game: prepare your position, hold off zombie waves and build up your arsenal between missions.

Simple moves. Cascading consequences.
An 8 × 8 color puzzle: place a piece, connect six matching blocks and let gravity trigger the next cascade.
BoardModel handles placement, gravity and connected color groups. BoardResolver computes the cascade sequence; effects and sound follow its events.
When space runs short, SpawnDirector favors pieces with more valid placements or searches for a shape, color and position that clears more blocks. Piece selection responds to the shape of the free space, not just its area.
The next piece can be picked up during a cascade, but placement waits until the board settles. Preview calculations do not change the live board.

I owned the technical implementation of graphics in Unity: integrating the work of artists and animators, developing rendering effects and optimizing scenes for mobile devices.
The project is on hold. These effects are shared with permission.
An adaptive voxel grid for 3D navigation. Cells intersecting geometry are subdivided; free cells form a graph for route search.
Subdivision creates eight child cells with face-based adjacency. Route processing uses intersections with cell faces before the demo agent follows a smoothed path.
Cell size trades geometric precision against graph size. The current search keeps open nodes in a list and sorts it at each step.
A Unity synchronization layer with RPCs, network variables and transform snapshots. Updates are batched into ticks; buffered states let remote objects move between network updates.
Attributes register RPCs; generic network variables define state. HostToClient, ClientToHost and Both control update direction, while Calm and Forced distinguish sending modes.
Interpolation plays back states with a short delay, keeping neighboring snapshots in the buffer to calculate the position between them. Smoother motion comes at the cost of that delay.
The client requires the paid Best Socket.IO transport and a separate server, which is not included in the repository. Prediction and reconciliation are outside the implemented feature set.
In my own games, I connect rules, gameplay systems, UI and visual feedback. In a team, I coordinate technical implementation with artists and animators.
I check graphics and performance on iOS and Android. Profiling helps me find the cause of slowdowns and decide what to optimize.
I use AI tools to prototype, explore solutions and automate routine work. I review generated code, make architectural decisions and take responsibility for the final implementation.
05 / WHAT’S NEXT
I’m looking for a team where I can take ownership of gameplay systems and tackle challenging problems alongside programmers, artists and game designers.
