Christopher Wagner speaking

// AUTHOR & PUBLISHER

Christopher Wagner

Independent SEO & AI Consultant at 1aSEO · Agent Builder

I work across technical SEO, agent building, and the systems behind reproducible publishing and research. XenCore Nexus is my independent record of what I build and observe around local LLM inference on Intel Arc hardware.

Background and approach

My professional background is in technical and strategic SEO for news publishers, with an ongoing focus on AI-supported editorial workflows. I led SEO work at two German media groups; the dated entries below link directly to public records for those roles.

For XenCore Nexus, I combine that publishing background with a personal interest in computer hardware and local AI systems. I document what I build and observe, and keep benchmark capture strictly separate from what this website can publish.

Publication boundary

Benchmark capture and presentation are intentionally separate. Capture happens in a dedicated benchmark repository; XenCore Nexus only presents a complete immutable bundle after a separate validator record covers the exact artifact digest. If that record is absent or fails, the public benchmark state remains unavailable.

XenCore Nexus is a personal, independent project. It is not affiliated with, sponsored by, or endorsed by Intel Corporation or other vendors mentioned here.

Project and publishing topics

These topics frame this project and its publishing scope. They are not individual credentials or a claim that every topic has a published benchmark result.
