Forward-Deployed / Applied AI Engineering

Ships MCP servers, sub-agent systems, and guardrailed LLM integrations that survive real enterprise workflows.

Simon Gonzalez De Cruz builds agent tooling that keeps working after the demo: typed tool surfaces, service-layer authorization, deterministic fallbacks, and the operational discipline of 12+ years running enterprise learning systems before AI existed as a job title.

  • mcp-video — a guardrailed FFmpeg MCP server for AI agents (67 stars / 18 forks, live)
  • 30+ merged PRs to third-party open-source projects (gajae-code 26+, anything-llm, mcp2cli, google_workspace_mcp, oh-my-claudecode)

Verifiable, not a slide deck

Public repos, merged pull requests, and a working compliance engine.

Every claim below links to something that actually runs.

mcp-video: one guardrailed FFmpeg surface

A free, open-source MCP server, Python library, and CLI that gives AI agents typed video-editing operations instead of raw shell commands: cutting, subtitles, audio, effects, repurposing, and preflight checks that catch bad output before it renders.

github.com/KyaniteLabs/mcp-video - 67 stars / 18 forks (live, 2026-07-06)

Merged fixes into production MCP projects

  • mcp2cli #56 - reused a cached redirect URI to fix an OAuth port-mismatch bug (2,200+ stars)
  • google_workspace_mcp #840 - added a socket timeout to stop indefinite hangs (2,700+ stars)
  • anything-llm #5790 - fixed an EventEmitter memory warning in the AIbitat agent framework (62,000+ stars)

A self-hosted, 4-node agent fleet

Two Macs, a GPU NUC, and a cloud VPS networked over Tailscale, running background workers against a self-hosted Git and CI control plane, with identity-verification scripts so a worker can never act as the wrong node. Built to find where sub-agent systems actually break at scale.

ComplyOS: a service-layer authorization engine

Service-layer authorization enforced once and shared across every surface: MCP tools, a REST API, a CLI, and a web dashboard all call the same permission checks, so access rules cannot drift between interfaces.

12 years before AI

He speaks both stakeholder and system.

Before the first MCP server, Simon spent 12+ years running the training and compliance systems that large organizations depend on. That background is why the guardrails in his agent tooling are not decorative.

Capital Group

Administered Workday Learning for 8,000+ associates, coordinated 10-15 global training programs a year, and diagnosed a broken compliance-training workflow before "guardrails" was an AI buzzword.

Southern California Edison

Project and program analysis inside SAP SuccessFactors, turning operational reporting needs into something leadership could act on.

PIMCO and American Red Cross

Bilingual training operations and disaster-response logistics, delivered in English and Spanish under real time pressure, not a classroom exercise.

Availability

Open to Forward-Deployed and Applied AI Engineer roles, plus contract engagements.

Long Beach, CA - remote-friendly. Delivers technical and stakeholder communication in English and Spanish.
