What I'm looking for

I’m looking for a team where I can build scalable iGaming and real-time WebGL experiences—combining provably fair gameplay, secure payments, and collaboration features—while collaborating closely on AI-driven workflows and performance optimization.

I’m a highly skilled developer focused on scalable, high-performance gaming environments—especially iGaming platforms with provably fair RNG. I’ve built and expanded casino solutions including slots, poker, roulette, blackjack, and sportsbook systems, with a strong emphasis on user engagement and secure, compliant gameplay.

Most recently, I built modular AI design canvas components for text and images, created a Three.js-based real-time 3D editor for object manipulation and scene management, and enabled real-time collaboration via WebSocket integration. Earlier roles included designing full-featured online casino and sportsbook platforms with wallet integration and secure fiat/crypto payments, implementing live betting with real-time odds, and delivering performance improvements for speed, reliability, and scalability.
