Available for commission work

I build high-performance game systems.

I'm Janxy, a game developer focused on performance-critical gameplay and tools. Whether you need a custom Unreal Engine plugin or a full Roblox game built and shipped, I deliver systems that scale.

Unreal Engine 5

Plugins built for scale

Two production-ready UE5 plugins that solve the same hard problem from both sides: render thousands of animated units, and move them as a coordinated crowd.

Vertex Animation Toolkit

VAT baking & instanced rendering

Bake Vertex Animation Textures from skeletal meshes and play them back on instanced static meshes, rendering huge numbers of animated characters without per-instance skeletal overhead.

  • Bake VAT from Animation Sequences, Composites & Montages
  • Instanced & Hierarchical Instanced Static Mesh support
  • Multiple LOD levels for distance scaling
  • Automatic vector calculation for cleaner anti-aliasing
  • Built-in material & runtime helper functions

Crowd Toolkit

RTS crowd movement & pathfinding

Move thousands of agents as groups under a single order. Built for real-time strategy, with flow-field and A* pathfinding, formations, and local avoidance that keeps units from stacking.

  • Group formations (blob, box, wedge) with shared pathfinding
  • Dual pathfinding: flow fields for crowds, spatial A* for individuals
  • Local avoidance for natural flow around obstacles
  • Runtime walls, per-agent speed & movement event callbacks
  • Marquee / radius selection and Blueprint + C++ APIs

Pair them: render a massive army with the Vertex Animation Toolkit and command it with the Crowd Toolkit.

Need a custom Unreal Engine plugin?

I take on commission work: rendering, simulation, and gameplay systems built to your spec.

Commission UE work

Roblox

Games I programmed

Full gameplay programming: core logic, UI, economy and live-ops systems built to ship and retain players.

+1 Fly Dragon Escape

Lead programmer

An incremental flight-escape game. I built the entire gameplay loop and the systems that keep players coming back.

  • Programmed the whole game logic & UI
  • Incremental upgrade / progression system
  • Custom analytics pipeline
  • Player-retention optimization

Mobs vs Zombies

Lead programmer

A lane-defense game in the spirit of Plants vs. Zombies, with a collection economy. I programmed every core system.

  • Programmed the whole game logic & UI
  • Mob defense system (Plants vs. Zombies style)
  • Grow-a-Garden style shop & economy
  • Egg-hatching logic

Have a Roblox game in mind?

I program Roblox experiences end to end: core systems, UI, economies, and the live-ops that drive retention.
