Framework Paralysis Is Real.

New AI frameworks launch monthly. LangChain, LlamaIndex, Semantic Kernel, CrewAI... the list never stops.

Analysis paralysis keeps you researching instead of building. You're afraid of learning the 'wrong' one.

Framework churn burns you out. What's hot today is deprecated tomorrow.

Fundamentals Beat Frameworks.

The AI Career Accelerator

The best framework to learn is the one you'll actually use to build something. But more importantly: master the underlying concepts and you can pick up any framework in days, not months.

Meet Your Mentor

Zen van Riel

When I started in tech, I was based in the Netherlands with no connections and only thousands of video game hours under my belt. Not exactly the ideal starting point.

My first tech job was software tester. One of the most junior roles you can start with. I was just happy someone took a chance on me.

I kept learning. Kept pivoting. But what actually accelerated my career wasn't more certifications or more code. It was learning to solve problems that matter and proving beyond a doubt that what I built solved real problems. That's the skill that stays future-proof, even with AI.

I've since worked remotely for international software companies throughout my career. Proof that the high-paid remote path is possible for anyone with the right skills and motivation. In the end, I went from a $500/month internship to 6 figures as a Senior AI Engineer at GitHub.

Now I teach over 22,000 engineers on YouTube. Becoming an AI-Native Engineer is a system I lived through and offer to you today.

"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

Which AI framework should I learn first?

Start with LangChain or LlamaIndex - they have the largest communities and most job postings in 2026. But here's the truth: the specific framework matters less than understanding the patterns. Learn how RAG pipelines work, how agents make decisions, how to evaluate outputs. With those fundamentals solid, switching frameworks takes days, not months. I help coaching clients build this foundation so they're never locked into one tool.

LangChain vs LlamaIndex - which is better?

LangChain excels at complex agent workflows and has broader integrations. LlamaIndex is stronger for RAG and document-heavy applications. But honestly? Most production systems use pieces of both, or neither - they use the OpenAI SDK directly. The 'best' choice depends on your use case. In coaching, we identify what you're actually building and match the tool to the job.

What if the framework I learn becomes obsolete?

It probably will - and that's fine. Framework-specific knowledge has a half-life of 18-24 months. Concept knowledge (prompt engineering, retrieval strategies, agent architectures) lasts for years. That's why I focus on teaching transferable skills. When LangChain 2.0 dropped breaking changes, my clients adapted in a weekend because they understood the underlying patterns.

How many AI frameworks should I know?

For most AI engineering roles: one or two deeply, plus awareness of others. Employers care more about your ability to build working systems than your framework collection. Deep knowledge of LangChain plus basic familiarity with alternatives beats surface-level knowledge of five frameworks. In coaching, we go deep on one framework while building transferable skills.

What frameworks do employers actually want?

Based on 2026 job postings: LangChain leads, followed by LlamaIndex and Semantic Kernel (especially for Microsoft shops). But here's the pattern I see: job listings ask for specific frameworks, but interviews test problem-solving. Can you design a RAG system? Debug a hallucinating agent? That's what lands offers. Framework syntax is googleable; architectural thinking isn't.

Can I get hired without framework experience?

Yes, especially if you have strong Python fundamentals and can demonstrate AI concepts through projects. Many companies are willing to train on their specific stack. What they can't easily train: problem decomposition, debugging complex AI systems, and the judgment to know when AI is the wrong solution. Those skills come from building, and coaching accelerates that dramatically.

Do I need prior AI experience?

Not necessarily. While some programming experience is helpful, many of my clients have successfully transitioned from web development, data science, or other technical backgrounds. We'll assess your current skills during our strategy call and create a personalized plan that meets you where you are.

How much time do I need to commit?

Most clients invest 10-15 hours per week, but this can be flexible based on your schedule. We'll have weekly 1:1 calls plus time for you to work on projects and learning. The key is consistency. Regular, focused effort beats occasional marathons.

What if I don't land interviews in 90 days?

You become a member of the AI Native Engineer community, and you stay and keep going. Career transitions take different amounts of time for everyone, and I'm not going to abandon you if things take longer. You get ongoing support through good times and bad.

How is this different from online courses?

Online courses give you content. 1:1 coaching gives you a personalized roadmap, direct feedback on your work, career strategy, interview prep, and accountability. You get answers to your specific questions and guidance tailored to your unique situation instead of generic advice meant for everyone.

What's the investment for 1:1 coaching?

Investment details are discussed during the 30-minute strategy call, where we'll assess your goals and create a custom plan. The program is designed to pay for itself quickly through your increased salary. Most AI engineers see a 20-50% pay increase.

Can I do this while working full-time?

Absolutely. Most of my clients work full-time and make steady progress. We'll schedule calls at times that work for you and create a realistic plan that fits your schedule. Consistency matters more than intensity.
