Be an AI Engineer in 2026. Learn this:
1. The Vector Stack:
- Embeddings (Text-to-Vector)
- Vector Databases (Storage)
- Semantic vs. Hybrid Search
2. RAG & Context:
- Advanced Retrieval (Reranking)
- GraphRAG (Knowledge Graphs + Vectors)
- Long-context window management
3. Pipelines & Orchestration:
- Chaining (Deterministic flows)
- Routing (Selecting the right model for the task)
- Frameworks: LangChain / LlamaIndex
4. The Agentic Layer:
- Tool Use (Search, APIs, Code Interpreters)
- Planning Loops (Reasoning before acting)
- Multi-Agent Orchestration (Swarms)
5. Evaluation & Testing:
- Golden Datasets (Establishing Ground Truth)
- LLM-as-a-Judge (Using strong models to grade weak ones)
- Metrics: Faithfulness, Answer Relevance, Recall
- Continuous Eval in CI/CD pipelines
6. Ops & Monitoring:
- Tracing (Debugging the chain)
- Cost & Latency optimization

Extracting text from a PDF can be quite tricky, even with the various libraries available.
So that's why @chideracode decided to make his own text-extractor tool.
In this in-depth guide, he walks you through building it with Node.js and TypeScript.

Web scraping often results in broken scripts, hitting rate limits, bot detection, and CAPTCHAs.
In this beginner course, @ania_kubow shows you a simpler API-based approach to collecting web data.
You'll extract structured JSON from various sites, then build an app that searches and downloads content locally.
