From JavaScript Developer
to AI Engineer
Python dominates AI, but JavaScript skills still transfer.
Learn the strategic path from JS to building AI products.
AI Seems Like a Python-Only World.
It's Not.
Every AI tutorial uses Python. You feel like JavaScript is invisible in the AI space.
You've invested years in the JS ecosystem and don't want to start from zero.
You're unsure if learning Python is mandatory or if JS-based AI paths exist.
JS Skills Transfer. Python Basics Help.
The World-Class AI Engineer Cohort
JavaScript AI tools are growing: LangChain.js, Vercel AI SDK, and every LLM has JS SDKs. Your async programming, API integration, and full-stack skills matter. Add strategic Python basics and you open both worlds.

Meet Your Mentor
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.
Real Results

AI Engineer
Built and deployed his portfolio piece, then landed the AI role
"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 AI tools exist for JavaScript developers?
The JS AI ecosystem is growing fast. Key tools: (1) LangChain.js for building AI chains and agents, (2) Vercel AI SDK for streaming AI responses, (3) OpenAI and Anthropic JS SDKs for LLM integration, (4) Transformers.js for running models in browser. For production AI features, especially chat interfaces and streaming responses, JavaScript is fully capable. Python becomes important for ML pipelines and model training.
Do I really need to learn Python as a JavaScript developer?
For AI engineering roles, some Python helps significantly. Most AI libraries, tutorials, and codebases are Python-first. The good news: Python basics take 2-4 weeks for experienced JS developers. Focus on: syntax differences, working with LLM APIs in Python, and reading existing ML codebases. You can build AI features in JS while using Python for backend AI logic. Many successful AI engineers use both.
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.
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.
