Learn Vector Databases.
Unlock AI Careers.
Vector databases power modern AI applications. Master Pinecone, Weaviate,
and Chroma to become the AI engineer companies are desperate to hire.
Too Many Options. No Clear Path.
Pinecone vs Weaviate vs Chroma vs Milvus. Everyone claims to be best. How do you actually choose?
Embeddings feel like magic. Without understanding them, you're just copy-pasting tutorial code.
Scaling from prototype to production breaks everything. Index strategies, costs, latency tradeoffs.

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.

"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."

AI Engineers With Vector DB Skills Are Rare
Frequently Asked Questions
Which vector database should I learn first?
Start with Pinecone if you want the fastest path to production with minimal ops overhead. It's fully managed and has the best developer experience. Learn Chroma for local development and prototyping. Consider Weaviate if you need hybrid search or want to understand more architectural concepts. The fundamentals (embeddings, indexing strategies, similarity metrics) transfer across all platforms.
Do I need to understand embeddings before learning vector databases?
Yes, but not deeply. You need to understand what embeddings are (dense vector representations of data), how they capture semantic meaning, and why dimension size matters. You don't need to build embedding models from scratch. Focus on using embedding APIs (OpenAI, Cohere, Sentence Transformers) and understanding when different models work better for different use cases.
How long does it take to learn vector databases for job readiness?
With focused effort: 2-4 weeks to understand core concepts and build basic RAG applications. 6-8 weeks to handle production concerns like chunking strategies, hybrid search, metadata filtering, and cost optimization. Most developers waste time bouncing between tutorials. A structured learning path with real projects gets you job-ready faster.
What vector database skills do AI job postings actually require?
In 2026, most AI engineering roles mention: experience with at least one vector database, understanding of embedding models and chunking strategies, ability to build and optimize RAG pipelines, knowledge of similarity search algorithms (ANN, HNSW). Senior roles also want production experience with scaling, cost management, and evaluation metrics for retrieval quality.
How do vector databases connect to RAG and LLM applications?
Vector databases are the memory layer for RAG (Retrieval Augmented Generation). You embed your documents, store them in a vector database, then query for semantically similar chunks when a user asks a question. These chunks become context for the LLM. Understanding this pipeline end-to-end is the most valuable skill for AI engineering roles building production applications.
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.
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.
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.
