I build SaaS platforms from scratch, and the agents that help teams ship them.

Senior fullstack engineer and hands-on technical lead in Amsterdam. Seventeen years of turning ambitious ideas into production software, with a strong preference for simple systems and fewer moving parts.

01 — What I do

Pragmatic engineering, end to end.

Agentic software delivery

Cloud-based agent workflows that turn scoped tickets into reviewable, tested branches, without lowering the bar on code quality.

  • Cursor
  • AI agents
  • CircleCI
  • Nx Cloud

Production SaaS architecture

Multi-region, multi-tenant platforms with authentication, observability and incident response. Built to stay cheap to run and boring to operate.

  • Angular
  • NestJS
  • Azure
  • PostgreSQL

Integrations & data

Complex synchronisation across distributors, PSAs and CRMs, data-heavy applications, and migrations that leave the system simpler than before.

  • Autotask
  • ConnectWise
  • HubSpot
  • TD SYNNEX

02 — How my teams ship

From a Jira comment to a live preview.

I designed and built a cloud-based agent harness at Salesbuildr. Engineers hand a scoped ticket to an agent, and every safeguard the team relies on stays in the loop. Smaller tickets now go from specification to reviewable implementation with very little manual coding.

  1. Ask

    An engineer comments on a Jira ticket; a bot launches a cloud agent.

  2. Understand

    The agent applies repository rules and skills to learn the codebase.

  3. Build & verify

    It implements the change, then runs linting, unit and E2E tests.

  4. Integrate

    Branch pushed to GitHub; CircleCI runs with Nx Cloud caching.

  5. Review

    An isolated Azure Container Apps preview, ready for peers and stakeholders.

Documentation, internal and public, stays current along the way, right down to the answers our Slack bot gives.

2009 Programmer Van Eldijk Studios

Where it all started.

05 — A different route in

I studied Slavic languages, not computer science.

A non-traditional path into engineering, and one that still shapes how I work: precise with language, curious about systems, and comfortable translating between people who think very differently.

Open to new work

Let’s build something worth shipping.

I’m available 1–2 days a week for temporary or part-time assignments: web applications, AI-assisted development workflows, architecture and hands-on technical delivery.
