PROFESSIONAL SUMMARY

Independent game creator with a strong focus on AI-assisted game development, creative problem-solving, and rapid prototyping. I combine analytical thinking, original ideas, and a deep interest in player psychology to design engaging gameplay mechanics and commercially viable game concepts.

I independently develop game concepts, define gameplay systems, establish production requirements, and use AI coding agents such as OpenAI Codex to implement and iteratively improve my projects. I take responsibility for evaluating gameplay, identifying issues, prioritizing improvements, and directing subsequent development iterations.

My background in business management and direct sales has strengthened my communication, decision-making, leadership, and commercial awareness.

I am particularly interested in opportunities that combine creative game design, AI-driven production, product strategy, and the development of engaging player experiences.
