A few pieces I can show, with the thinking behind them.
I'm a Senior Systems Designer on Horizon Hunters Gathering, a co-op action game still in development. Nothing I can show here yet.
Closing distance in an extraction shooter is usually a mistake. Taurus makes it pay off. Bull Charge punches him through the enemy line; Power Pylon, his deployable shield, turns wherever he stands into ground the team can hold. A brawler whose mistakes are his own: positional and readable.
Support falls apart when healing is a separate job from fighting. So Trenchwalker puts the sustain on the gun: the Leech Gun pays health for dealing damage, making aggression and survival the same move. The Hybrid Grenade heals allies and hurts enemies on one cooldown. Lifeline and threat, no tool-swapping.
Looks like an ambusher, plays as space control. Blink gives a short invulnerable reposition, so you beat him by predicting where he has to go, not out-shooting him. Plasma Arc punishes players for bunching up. Every exit planned before the entrance.
Weaver holds ground. His Energy Barrier turns positioning into a team resource, deciding which sightlines and fights exist at all. The Minigun rewards committing to that ground with heavy damage, at the cost of mobility. The skill is where and when you drop the barrier. The hero a team builds around.
One player gets a live editor for the match while everyone else fights inside what they build. The hard part is authority: enough power to shape the fight, not so much that everyone else is a spectator. It pushed user-generated content forward in Arma, a franchise that pioneered it.
Built to work on a couch two meters from a TV and on an ultrawide up close. Elements scale and give way by what matters most in the moment, no fixed layouts. I built the editor too, so designers tuned HUD behavior live instead of waiting on a build.
My job here was engineering: multiplayer, the launcher backend, and the hero and ability frameworks designers built on. It's where I learned what designers do to frameworks built without them in the room.
A narrative adventure where you play the family cat, point and click. I handled the gameplay side: the NPC AI, the cat's point-and-click movement, mission logic, a stack of gameplay mechanics, and the UI code.
