Principal Systems Architect | AI Performance Engineering

  • 🔭 Current Focus: Hardware-aware LLM optimization, GPU orchestration, and custom Triton kernels.
  • 🚀 Nebius Academy: Mastering high-performance infrastructure for the Israel National AI Supercomputer.
  • 🛠️ Experience: 25+ years in low-level R&D, from compilers to high-frequency trading engines.

⚡ AI Infrastructure & Systems Mastery

  • AI Compute: Triton, CUDA Kernels, GPU Memory Optimization (HBM3/SRAM), Inference Scaling.
  • Systems Architecture: High-Performance Computing (HPC), Distributed Clusters, C++, Go, Rust.
  • MLOps: GPU Orchestration, Docker/K8s for AI, Latency-Critical Backend Systems.
  • Legacy Expertise: Compiler Design (Lex/Yacc), R&D, Real-time Search, and IoT Data Streams.

🧪 Performance Labs (Nebius Academy)

I am documenting my deep-dive into AI Performance Engineering here:

💼 Strategic Engineering Leadership

Founder & CTO | vkhey! Mar 2025 – Present

  • Architecting high-performance multimodal RAG systems (text, video, audio) for enterprise scale.
  • Bridging 25 years of systems engineering into the "plumbing" of the agentic AI era.

Principal Developer | Labguru May 2023 – Mar 2025

  • Engineered a first-of-its-kind cross-server communication platform for distributed lab environments.
  • Led technical implementation for ISO 27001, GDPR, and SOC 2 compliance in high-security environments.

Principal Developer | Kando Jan 2021 – Mar 2023

  • Tech lead for the National COVID-19 monitoring project, managing massive IoT data streams.
  • Optimized data-processing algorithms and high-performance dashboards for national-scale infrastructure.

Principal R&D Dev | SeekingAlpha Jul 2015 – Jul 2020

  • Built multi-million dollar ad products and high-throughput analytics pipelines for 20M+ monthly users.

🛠 The Polyglot Foundation

Note: While I am a polyglot (Python, Ruby, Node.js, Go, C#, C++), I specialize in System Design where the choice of tool is dictated by hardware constraints and performance requirements. Currently spending my days in Triton and C++ to squeeze every TFLOP out of the H100.
