Game Design & Systems Portfolio

This portfolio showcases selected work in game design, systems, balancing, playtesting, simulation and gameplay prototyping.

My background combines professional software development experience with hands-on game design. My projects focus on designing and iterating gameplay systems, evaluating player experience, and using playtesting, data and simulation to support design decisions.
