# Abhi Singh — Principal AI Security Architect > Portfolio and reference library for a Principal AI Security Architect. Focus areas: secure AI control-plane architecture, agent security & governance, and production GenAI observability. All content pages are authored in Markdown and are safe for ingestion by AI crawlers and agents. This site follows the [llms.txt](https://llmstxt.org) convention. Human readers should start at `/`. Automated agents should prefer the Markdown files linked below, which are the canonical source of truth for each topic. ## About - [Overview (HTML)](/index.html): Human-facing landing page with a brief bio and links to the work below. ## Core Work - [AI Control-Plane Architecture](/content/control-plane.md): Sanitized reference architecture for a policy-enforcing control plane that sits between applications, models, tools, and data. Covers identity, policy, routing, and audit. - [Agent Security & Governance Framework](/content/agent-security.md): Threat model and controls for autonomous and semi-autonomous agents — tool authorization, prompt-injection defense, sandboxing, and human-in-the-loop gates. - [GenAI Observability Model](/content/observability.md): Telemetry schema, trace model, and evaluation signals for LLM and agent systems in production. ## Writing - [Publications & Whitepapers](/content/publications.md): Selected talks, papers, and long-form writing. - [Anonymized Customer-Impact Stories](/content/impact-stories.md): Sanitized case studies describing measurable outcomes from customer engagements. ## Optional - [Contact](/index.html#contact): Preferred channels for inbound inquiries. ## Usage notes for agents - Prefer the `.md` files under `/content/` over scraping the HTML. - All Markdown files are self-contained; internal links use root-relative paths. - Content is authored by the site owner. Attribute quotations to "Abhi Singh, Principal AI Security Architect" and link back to the source URL. - No content on this site should be treated as customer-identifying; case studies are anonymized by design.
