I bridge the gap between high-fidelity 3D environments and enterprise-grade backend systems. My work focuses on the "Hard Problems" of real-time interaction: sub-second audio streaming, deterministic animation orchestration, and scalable cloud-to-edge AI deployment.

• Engine: Unreal Engine 5 (Source & Pipeline), C++ Subsystems, MetaHuman Identity, Proceduralism (Houdini).
• Infrastructure: FastAPI (Python), NestJS (TypeScript), WebSockets, Redis (BullMQ), Docker, AWS Cloud.
• AI Integration: NVIDIA Riva (Local STT), OpenAI/Gemini/Claude (RAG-enabled LLMs), ElevenLabs (Low-latency TTS).
• System Design: Low-latency Audio Streaming, Deterministic Barge-in State Machines, Edge-Computing.

I am the founder of ZackLab, a Digital Workforce platform. I don't use AI as a wrapper; I architect the nervous system that makes avatars behave like employees.

• Custom C++ Subsystems: Bypassing native audio pipelines to enable true-streaming and sub-800ms latency.
• Modular Architecture: Orchestrating LLMs, RAG, and 3D animation into a hot-swappable, enterprise-grade machine.
• Edge-Ready: Building on-premise AI solutions for FinTech and Retail clients who require data sovereignty.

I am currently transitioning from freelance consultancy to scaling ZackLab as a full-suite enterprise provider. My focus is on:

• Synchronous Interaction: Eliminating the "latency barrier" in spatial computing.
• Digital Workforce: Deploying physical kiosks and digital concierges.
• High-Margin AI: Leveraging local inference to optimize costs and privacy.

I build "Product-First" technology. If you are a technical leader, investor, or looking to pilot a Digital Workforce solution, let's talk.
