Stack covered Python OpenAI / Claude / Gemini Hybrid RAG Tool-Calling Agents Evals & Guardrails

01 / Structured Curriculum

Four readable paths. Zero passive fluff.

Every course is built like a modern engineering handbook — sidebar curriculum, runnable code blocks, architecture diagrams, “Watch out” failure boxes, and progress tracking.

TRACK 01 · BEGINNER 8 lessons · ~5 hrs

Python for AI Developers

Virtual environments, type hints, async HTTP calls, JSONL dataset pipelines, NumPy/Pandas essentials, and a complete data-prep project before your first model call.

Includes: Dataset Prep Project Start reading free →

TRACK 02 · CORE 8 lessons · ~6 hrs

LLM Fundamentals

Tokenization, next-token probabilities, system/developer/user roles, temperature & top-p sampling, structured JSON outputs, and latency/cost instrumentation.

Includes: CLI Assistant + Logger Start reading free →

TRACK 03 · INTERMEDIATE 8 lessons · ~6 hrs

Building RAG Systems

Document chunking trade-offs, dense embeddings, vector indexes, hybrid BM25 + vector search, cross-encoder reranking, score floors, and grounded citations.

Includes: Chat-with-Docs Engine Start reading free →

TRACK 04 · FLAGSHIP 10 lessons · ~7 hrs

Generative AI & Agents

Tool calling schemas, ReAct loops, state graphs, memory & context compaction, human-in-the-loop approvals, and automated evaluation suites for agents.

Includes: Multi-Step Research Agent Start reading free →

02 / The Production Gap

Every AI demo works on five tweets. Production breaks at 2:00 AM.

✗ TUTORIAL DEMO STACK Breaks under real traffic

“Just wrap an LLM call and stuff top-5 chunks into the prompt.”

01Blindly splits PDFs every 500 characters — slicing tables and policy clauses in half.
02No similarity score floor — when retrieval misses, the model confidently invents a policy.
03Unbounded agent loops — one flaky tool call triggers 12 retries and burns $40 in tokens.
04Evaluated by “vibes” on 3 manual prompts instead of a repeatable golden dataset.

✓ PRODUCTION AI ENGINEERING What we build here

Deterministic guardrails around probabilistic models.

01Structure-aware chunking + hybrid BM25 & dense retrieval with cross-encoder reranking.
02Explicit score thresholds and abstention paths ("I don't have enough context") with inline citations.
03Strict tool schemas, step budgets, idempotency keys, and human-in-the-loop checkpoints.
04Automated faithfulness, recall@k, latency, and cost-per-task evaluation before every deploy.

03 / Built for Deep Focus

Read at your speed. Ship as you go.

No 40-minute rambling videos to scrub through when you need one code pattern. Every lesson combines clear intuition, copy-ready Python, and embedded video walkthroughs.

04 / The Path

The AI Developer Roadmap.

Eight stages from your first Python script to shipping production AI products. Start at stage one, or jump in wherever you are — each free course maps to a stage.

AI Developer Roadmap in 8 stages: 1 Foundations (Python, Git and GitHub, Linux, problem solving); 2 AI/ML Basics (math for ML, Pandas and NumPy, ML algorithms, model evaluation); 3 GenAI and LLMs (LLM fundamentals, prompt engineering, function calling, RAG basics, model APIs); 4 RAG (architecture, vector databases, embeddings, chunking and indexing, evaluation); 5 AI Agents (agent architecture, tool use, multi-agent systems, orchestration, memory and planning); 6 Azure AI Foundry (model deployment, RAG with Azure AI Search, agents and tools, monitoring); 7 MLOps (model versioning, CI/CD for AI, evaluation and observability, cost optimization); 8 Advanced and Specialization (fine-tuning, domain AI, production deployment, security and governance, end-to-end AI products).
