Romania

Message

At Hacksaw Studios, I ship production slot frontends in a custom Haxe / Heaps.io engine. I build presentation, UI behaviour and gameplay-facing logic, shaping feature flows with finite state machines, ECS and dependency injection.

At Outworld Games, I built and published complete slot-game frontends in TypeScript, PixiJS and Svelte. Mythic Totems, Prophecy of Ra and Forest Friends: Egg Hunt shipped to Stake.

On Space Raptors, my personal mobile game project, I implemented the animated UI layer and player-facing feature flows. I also built Battle Pass and in-game currency conversion features, with Google Play Games, Apple Game Center, IAP, ads and cross-save integrations.
