Technical Game Designer / Gameplay Developer

I focus on designing gameplay flows, mechanics, and player experiences, then turning ideas into playable, testable features through prototyping, playtesting, and cross-disciplinary collaboration.

I am interested in working with teams that value hands-on gameplay design, practical prototyping, and iterative development. This can be for building a new concept or improving an existing project.
