How Do I Build Production AI Systems?

Building AI demos is easy. Shipping reliable, scalable AI
that handles real traffic? That's a different skill set entirely.

The Demo-to-Production Gap Is Real.

Your prototype works in Jupyter. In production, it crashes under load, costs spiral, and latency kills UX.

No observability means you're blind when things break. And in AI systems, they break in subtle, expensive ways.

Security, compliance, and responsible AI aren't optional in production. They're blockers you haven't planned for.

Production AI Requires a Systems Mindset.

The World-Class AI Engineer Cohort

Moving from demos to production isn't about better models. It's about engineering discipline: cost controls, graceful degradation, monitoring, caching strategies, and designing for failure. These patterns aren't taught in courses—they're learned from practitioners who've shipped.

1

Learn the Patterns

Caching, batching, fallbacks, rate limiting

2

Build Observability First

You can't fix what you can't see

3

Ship with Guidance

Learn from someone who's deployed at scale

Meet Your Mentor

Zen van Riel

My aim has been the same for years: become a world-class AI engineer. Every career move I've made has been measured against that.

I started as a software tester on a $500/month internship in the Netherlands. Taught myself to code, learned to ship real systems, and worked my way to Senior Engineer at GitHub.

Then I left GitHub. I joined an AI research lab as Member of Technical Staff, where I currently build products for secure AI monitoring.

The cohort draws directly from my real experience so you can make progress fast.

I run this special cohort with only a few people because hands-on work with me is what it takes to bring you to become a world-class AI engineer.

"The coaching played a huge part in my success. I focused on AI fundamentals, the certification path, and soft skills like professional writing. Having access to expert guidance gave me confidence during interviews and helped me feel I was on the right path.

I built my own platform (simple but functional) and deployed it on AWS. I used it in my portfolio and showcased it during interviews. The way complex topics were explained, especially the restaurant analogy for AI systems, really stuck with me. Focusing on doing the basics well was absolutely essential."

Frequently Asked Questions

What's the real difference between demo AI and production AI?

Demo AI optimizes for impressive one-off results. Production AI optimizes for reliability, cost efficiency, and maintainability at scale. In production, you need to handle rate limits, manage costs (often $10K+/month in API calls), implement graceful degradation when services fail, add comprehensive logging and monitoring, ensure security and compliance, and design for 99.9% uptime. These concerns don't exist in demos, which is why the transition feels so jarring.

What are the biggest challenges in production AI systems?

The top production challenges in 2026: 1) Cost management—LLM API costs can explode without caching, batching, and model routing strategies. 2) Latency—users won't wait 10 seconds for a response, so you need streaming, async processing, and smart UX patterns. 3) Observability—when AI outputs go wrong, you need traces, evaluations, and monitoring to diagnose issues. 4) Reliability—handling API failures, rate limits, and model degradation gracefully. 5) Security—prompt injection, data leakage, and compliance requirements.

Where can I learn production AI engineering patterns?

Most courses focus on model training, not production deployment. Your best resources: 1) Study open-source production systems (LangChain, LlamaIndex architectures). 2) Read postmortems from companies running AI at scale. 3) Build side projects that force you to handle real constraints. 4) Work with a coach who's actually deployed production AI—they can teach you patterns in weeks that take months to discover alone. The fastest path is learning directly from practitioners.

How much time will this take?

You'll spend 3 hours every Tuesday in the live session and roughly 3 hours of async work in between, for 8 weeks. The Tuesday session time is fixed.

How do I build my first production AI system?

Start small but real: 1) Choose a project with actual users (even if it's 10 people internally). 2) Set up observability from day one—logging, cost tracking, latency metrics. 3) Implement caching early (you'll thank yourself later). 4) Design for failure: what happens when the API is down? 5) Add rate limiting and cost caps before you need them. 6) Deploy incrementally with feature flags. The goal isn't perfection—it's learning the production loop of deploy, monitor, fix, improve.

I've signed up for cohorts before and dropped out. How is this different?

It probably isn't, and you should hold the money. Most cohort dropouts are people who couldn't articulate what they were shipping when they signed up. That's why the consult exists, and why I turn down most applications. If we get on the call and you can't tell me what you'll have shipped at the end of week 8, I'll point you to the AI Native Engineer community until you can.

I'm not pivoting careers. I want to build a product. Does this still work?

Yes, the cohort works for people shipping their first serious AI system whether the goal is to land a senior role or to launch a product. The shipped system serves both equally well.

Do I need prior AI experience?

You need to be able to code in Python or TypeScript. Complete beginners can follow the classroom they get access to before the cohort sessions to come in well-prepared.

What does it cost?

It's a four-figure investment that we discuss during the 30-minute consult, alongside whether the cohort is the right fit for your project.

Can I do this while working full-time?

Yes, most attendees do. The live session is one Tuesday a week and the async work fits around your existing schedule, as long as you can carve out roughly 6 hours a week.

I accept those who have the highest chance of success.

In the 30-minute call we discuss your goals and whether you are ready for the program.
