Senior AI / Gameplay / Full Stack Engineer

Joe
Schwartz

I build games across the full stack, then use Generative AI to push both gameplay and production further.

99.38%Less time from card concept to playable production content through AI tooling.
98.57%Lower server costs through deterministic, seed-driven combat simulation.
Veteran expertiseTrained by 30+ year Original WoW and StarCraft veteran Twain Martin.

01 Practice

Build the whole playable system.

Moment-to-moment gameplay, server architecture, runtime generation, editor tooling, production UI, and the integration work that turns separate systems into a shippable game.

Accelerate without losing craft.

I apply Generative AI across engineering, design, 2D and 3D art, animation, VFX, terrain, NPCs, and tooling where it improves iteration and creates new player-facing mechanics.

02 Capabilities

Engine + Gameplay

Systems that feel good in the player’s hands and hold up in production.

Independent R&D

Unreal Engine MMO

Solo MMO prototype work spanning C++ motion-matching characters, efficient backend architecture, replicated multiplayer, remote user testing, procedural open-world terrain, generated-world previews, and an LLM interface for procedural settings.

An adjacent asset pipeline generates 2D art, converts it to 3D, rigs humanoids, imports assets, and spawns the result into runtime and editor workflows.
