In this portfolio there is no single professional project (usually NDC) Links coming from my free-time space.

Innovative software engineer with 15+ years of experience in web, real-time graphics, and multiplayer systems. Specialized in canvas2d, WebGL/WebGPU, custom rendering engines, networking, and cross-platform development. Proven ability to design, implement, and ship full applications — from backend servers to front-end rendering engines — with high performance and scalability.

Graphics / Engines: WebGL, WebGPU, OpenGL ES, GLSL shaders, Three.js, Ammo.js, raycasting, BVH animation, physics integration.

Front-End: JavaScript, TypeScript, HTML5 Canvas2D, JQ, React, Vue.js. (also experience in native android/ios apps)

Back-End & Networking: Node.js, WebSockets, WebRTC, Kurento, MongoDB.

Game / Interactive Media: UE4, Unity, custom game engines, multiplayer architecture, cross-platform builds.

Other: Virtual DOM concepts, CustomEvents, performance optimization, responsive UI, mobile optimisation.

Make my own game engines for 2d/3d. Used cannon.js/ammojs for physics.

• Matrix-engine WebGL library based on glmatrix ver 2.xx. Can be downgraded with url param to the glsl 1.1. For networking used broadcaster Kure / kurento openvide driven. Demos: https://maximumroulette.com/apps/matrix-engine/examples-build.html

• Visual-ts Game Engine 2d canvas game engine based on Matter.js 2D physics engine for the web supported with backend node.js/mongoDB and visual GUI tool 2d map creator/python3. https://github.com/zlatnaspirala/visual-ts-game-engine

• Safir (similar to reactjs but faster) Light virtual DOM. Tech: Based on ECMA6 programming paradigms builded on Template Literals, CustomEvents, Custom Tags. Alternative software - High Performance

Database used MongoDB

• REST HTTP SERVER - HANDLING ACCOUNT SESSION
• Also socket access

ROCKET CRAFT - UE4 projetcs In ue4.24 I use http/https request data format JSON.

• BarbarianRoadMashines
• Shoot the zombie
• Hang3d FPShooter

Special skills Tools (python):

• I made a 2d map creator for my platformer 2d game. https://github.com/zlatnaspirala/creator-2dmap
• I made visual editor with python (kivy). https://github.com/zlatnaspirala/cross-k
• Wrap own webgpu engine intro reactjs https://github.com/zlatnaspirala/me-webgpu-react
• Remote control with web page Opensource part: https://github.com/zlatnaspirala/wizard-service c# part commercial.

In best day i was top 14 but 3-4 year inactivity... Hackerrank AI Leaderboard https://www.hackerrank.com/leaderboard?page=3&track=ai&type=practice Filter Serbia : https://www.hackerrank.com/leaderboard?filter=Serbia&filter_on=country&page=1&track=ai&type=practice

Shader playground - I need more skills in this area. All shaders will be part of buildin matrix-engine custom shaders but only with MIT Licence.
