Mat Siems — AI Engineer & Consultant.

15+ years of technical delivery across AI systems, backend engineering, and cloud automation. LLM architectures, multimodal generation, and end-to-end AI pipelines — shipped in production.

Summary

AI Engineer and Workflow Automation Consultant with 15+ years of technical delivery across AI systems, agentic coding, and cloud automation.

Specialises in LLM architectures, Claude Code / multi-agent workflows, and full-stack AI products — Next.js on the front, Supabase + MongoDB on the back, Vercel on the edge.

Ships 13 production sites, 34 marketing pages, and a fleet of managed agents — all orchestrated from a single cockpit built with the same stack I sell.

Current tech stack

The toolkit, today.

What I reach for in 2026 — Claude Code for agentic build, Next.js + Vercel for shipping fast, Supabase + MongoDB for data.

Fleet, agents, content — shipped.

Three builds that illustrate the stack: an orchestration cockpit, an agent chain, and a daily content engine — all running in production.

APPAI
Fleet cockpit — 13 sites, one dashboard

Next.js 15 orchestration cockpit for a fleet of 13 production sites. PBI → build → preview → push → deploy, all from one interface. JSON-on-disk registry, Supabase auth, Vercel-survivable read-only mode.

  • Next.js 15
  • Supabase
  • Vercel
  • Claude Code
Outcome

13 sites live, all on the same push-to-Vercel pipeline, managed from a single cockpit.

ABC Agent Squad
19-agent chain from brief to shipped

Discovery → Strategy → Design → Engineering → Distribution, each a Claude Code skill in production. IntakeAgent turns a voice memo into a Project Card; ProposalAgent outputs a full proposal pack in one POM.

  • Claude Code
  • Skills + Hooks
  • MCP
  • Multi-agent cowork
Outcome

Every client engagement runs through the chain — median time from brief to proposal: < 1 POM-day.

Daily Content Engine
PAD · LAD · IAD · AAD · VAD — on autopilot

Five daily workflows (page, list, image, audio, video) running on a cron via AIOS. Each generates, archives, and upserts to MongoDB AIDB.DAILY. ≈810 top-100 lists in the archive, 200+ hours of audio, 1,000+ videos.

  • AIOS
  • MongoDB
  • Claude API
  • Gemini Imagen · ElevenLabs · Veo
Outcome

Six content streams running daily — one human touch point per stream (approval).
