Frontier Systems& GPU Architecture

Frontier AI Infrastructure · GPU Performance & KV Cache · Tier-1 Upstream Compilers · Systems Assurance & Threat Modeling

Principal systems architect, software developer, and founder. Advising frontier AI labs, sovereign cloud clusters, and high-velocity engineering organizations on low-level GPU memory hierarchies, KV cache engineering, custom Triton/CUDA kernel fusion, CPython 3.14t free-threading, and compiler-grade guarantees across OpenAI Triton, LLVM, Meta Velox, and DuckDB—paired with hands-on software development and end-to-end execution across mobile apps, enterprise web platforms, and autonomous systems.

Core Thesis

AI-accelerated execution. Human-directed judgment.

Deep technical rigor paired with broad commercial execution: connecting runtime behavior, hardware realities, and cloud infrastructure directly to user value, product velocity, and business growth across any industry.

15-Minute Invariant Protocol
“In 15 minutes, we pinpoint the hidden memory wall bottlenecks and KV-cache leaks before you burn $200,000 on cloud compute. Zero plumbing revealed.”
