- Game Creator -

I am a game developer with a multidisciplinary background in technical game design, QA testing, and gameplay programming. I work at the intersection of these roles, focusing on building, analyzing, and improving gameplay systems to deliver high-quality player experiences.
My experience covers the full lifecycle of gameplay features: from design and implementation to testing, debugging, and iteration. This allows me to approach problems from multiple angles — understanding player intent, system behavior, and technical constraints — and to identify issues efficiently while contributing to clear and actionable improvements.
I am comfortable working directly in-engine using Unity (C#) and Unreal Engine (Blueprints/C++), whether it is to prototype mechanics, validate gameplay behaviors, or investigate bugs. I particularly enjoy working on gameplay systems such as AI, combat, progression, and player feedback, with a strong attention to detail and overall coherence.


Key Skills

  • Gameplay Systems: Design, implementation, testing, and iteration of mechanics and interactions.
  • QA & Testing: Functional testing, bug reproduction, reporting, and gameplay analysis.
  • Debugging: Identification and investigation of issues across gameplay, AI, UI, and interactions.
  • Prototyping: Rapid iteration of ideas directly in-engine.
  • AI & Systems Design: Behavior design, balancing, and player experience tuning.
  • Engine Expertise: Unity (C#) and Unreal Engine (Blueprints/C++).
  • Collaboration: Working across design, programming, and production with clear communication.
