What I'm looking for

I'm looking to design and tune gameplay systems, encounters, progression, and levels in a collaborative small multidisciplinary team, using playtests and clear documentation to improve the player experience.

I've designed NPC systems, artifact mechanics, difficulty curves, and mobile performance budgets for Target Force, a 30-player mobile PvPvE game in development at Highavenue Creative Labs.

At Avian Hearts, I owned multiple levels for Mechanical Fury from blockout to first playable, shaping traversal, exploration routing, combat encounters, scripted events, and player guidance ahead of its Early Access launch.

I use playtests to identify why a section is not landing, then re-route traversal, re-space encounters, or improve landmarks within scope. I write and maintain the documentation programmers, artists, narrative teams, and non-designers build from.

My solo work includes a playable crafting-economy prototype with a Python tuning simulation, a fitness RPG progression system, and an action-adventure design bible. Across Unreal Engine and Unity projects, I've shipped mechanics, levels, VFX, and gameplay systems from concept through release.
