Gameplay Programmer — Unreal Engine 5 · Unity · Portfolio · LinkedIn · kaan.altayofficial@gmail.com

Five years building games, three professionally. Sole gameplay programmer on Grog 'n Glory (UE5 co-op open-world pirate action-adventure, publicly exhibited demo) — ship physics, custom navigation, behavior-tree AI, crew-management systems, Chaos destruction, co-op replication. Currently client developer on BladeX: End of Darkness, a live-service mobile ARPG in closed beta — FairyGUI UI architecture, xLua hot-update infrastructure, client-server state sync.

Production code stays private, so I rebuild the ideas in the open:

naval-navigation-sample UE 5.5 · C++ — threat-aware pathfinding for wind-driven sailing ships: sea-grid cost field, predictive helmsman, event-driven replanning. Engine-free core; 30 in-engine tests plus a 600-assertion standalone harness.
ui-reddot-system Unity · FairyGUI · xLua — a production-shaped red-dot notification system with hot-updatable Lua rules, page-scoped dot lifecycles, and token-based seen tracking. 107 automated tests.
hot-update-ab-test Unity · C# · xLua · FairyGUI — a LiveOps A/B testing framework: deterministic layered bucketing, exposure logged at view time rather than at assignment, a sample-ratio-mismatch guardrail measured over the exposed population, kill switches, and variant behavior delivered as hot-updatable Lua. 398 distinct tests (238 engine-free core tests that also run inside Unity, plus 118 Unity-only EditMode and 42 PlayMode).
