Technical Artist & Graphics / Gameplay Programmer
I build real-time rendering, shaders and tools, and I ship live games. My Roblox games have passed 37 million visits, and my BA thesis rendered carpets fiber by fiber in real time.
Live games first, then rendering research and the shader and tool work behind it.

A multi-stage surface cleaning workflow (dust, wet, foam, scrub, rinse, squeegee, dry) on dense real-time carpet fibers, with tools, jobs and a work-order HUD.

Shells 5.5× faster up close · fibers 1.3× faster at room distance
BA Thesis · Cologne Game Lab, TH Köln · 2025
I built two carpet renderers in Unity and measured them against each other: a procedural fiber shader (hardware tessellation, geometry shaders, Kajiya-Kay shading, screen-space LOD) and 64-layer shell texturing with normal mapping. Both were checked against reference photos and profiled on an RTX 3070.
Read the case studyLighting sampled per brush stroke
Makes 3D scenes read like 2D paintings by locking lighting to each stroke's centre instead of each pixel. Includes a custom tool that encodes stroke centres into textures.

One-click snow on any scene
Unity editor tool that bakes a NavMesh, extracts its geometry and extrudes it into snow layers with occlusion, on any object type.
View ProjectDebris that hugs any terrain
Shader that fits debris to terrain height while keeping each piece's shape, using vertex colours to store mesh part centres for height sampling.

Carpet Cleaning Simulator (31M+ visits, 728K+ favourites) and Drain Simulator (6.1M+ visits). I build the gameplay systems and run live updates and seasonal events.
Thesis: real-time fiber and cloth rendering techniques for carpet materials.
Built VFX with Shader Graph and particle systems, AI creatures with behaviour trees, and the inventory system. Profiled and fixed frame drops on weapon switching caused by unnecessary texture memory allocation and oversized textures.
Interactive Unity apps built with Unity UI and DOTween, with a custom styling system modelled on CSS classes. Tight deadlines, strict quality bar.
2D platformer controller, dialogue system and first-time-user tutorial, plus a graph-based spell creation system for custom spells.
Rescue Robots Sniper Survival, a mobile FPS released on Google Play: fixed character controller bugs, implemented new UI and a minimap.

Where rendering meets gameplay.
I'm Alla Eddine Rakik, a game programmer and technical artist based in Cologne. I graduated in Game Programming from Cologne Game Lab (TH Köln) in 2025.
Most of my work sits where rendering meets gameplay: custom shaders and VFX, editor tools that save artists time, and the profiling that keeps it all at frame rate. At BlueGoo Games I led technical art and tracked down frame drops caused by wasted texture memory. In my thesis I built two real-time fiber renderers and measured exactly where each one wins.
Today I build and run live games on Roblox, where my two titles have passed 37 million visits. I work in English (C2), French (C1) and Arabic (native).
// Kajiya-Kay fiber highlight, the model behind my thesis fiber shader
float FiberSpecular(float3 T, float3 V, float3 L, float exponent)
{
float3 H = normalize(L + V);
float TdotH = dot(T, H);
float sinTH = sqrt(1.0 - TdotH * TdotH);
// fade the highlight when the light is behind the fiber
float atten = smoothstep(-1.0, 0.0, TdotH);
return atten * pow(sinTH, exponent);
