Managing Engineer · AI & Platform · Amsterdam

I build software with teams of agents and humans.

Managing Engineer at Nationale-Nederlanden. 15+ years building platforms for banking, pensions and hosting, and now leading teams where AI agents and engineers ship together through pipelines built to catch problems before release.

What I do

Three disciplines, one system.

AI that works in production needs more than a model. It needs orchestration, and it needs a pipeline that won't let bad changes through.

01

AI Engineering

LLM-powered products from prototype to production: tool use, retrieval, evals and guardrails. I treat models as components with contracts, not magic.

  • Claude & LLM APIs
  • Tool use / MCP
  • RAG & evals
  • Prompt & context design
02

Agent Orchestration

I have spent years recruiting, mentoring and leading scrum teams. Now I run coding agents the same way: clear tasks, scoped permissions, isolated workspaces and human checkpoints where judgement matters.

  • Multi-agent workflows
  • Task decomposition
  • Human-in-the-loop review
  • Sandboxed execution
03

CI/CD & Platform

Pipelines that make shipping boring, even under DNB and EU regulation. Every change is built, tested, secured and provisioned as code before anyone hits merge.

  • GitHub Actions
  • GitLab CI
  • AWS · CloudFormation
  • Kubernetes
  • Cloudflare
The roster

One lead. Six agents. Three humans. One loop.

This is the team from the mission above. Every card is live: dispatch a mission and watch who picks up what.

  1. 01

    Humans set direction

    People own the goals, the trade-offs and the final call. Agents never merge to production on their own.

  2. 02

    Agents do the volume

    Research, scaffolding, refactors, tests and docs run in parallel — each agent in its own isolated branch.

  3. 03

    Pipelines enforce trust

    Type checks, tests, previews and audits gate every change, whoever (or whatever) wrote it.

  4. 04

    Everything is observable

    Every task, diff and decision leaves a trail: PRs, logs and reviews you can read later.

Shipping

This site ships itself through the pipeline it describes.

Every change to ghiata.com runs through GitHub Actions: built, type-checked, previewed on its own pages.dev URL, then deployed to Cloudflare's edge on merge.

● deploy.yml · main running…
  1. Plan agent decomposes issue
  2. Build astro build
  3. Check types & lint
  4. Review agent + human
  5. Preview pages.dev URL per PR

  • 01
    Preview per pull request

    Reviewers — human or agent — click a live URL instead of reading a diff blind.

  • 02
    Gates before merge

    Builds and type checks are required status checks. Red means it doesn't ship.

  • 03
    Edge deployed

    Static output served from Cloudflare's global network with zero servers to babysit.

  • 04
    Kept current

    Dependabot opens update PRs weekly; the same pipeline vets them.

Track record

Fifteen years of commits to systems that had to work.

Banking, insurance and hosting: software that faces regulators, auditors and millions of customers. Here's the history, the way I'd read it.
