Week 24: Month 6 Capstone, Master Portfolio & The Senior AI Engineer Interview Gauntlet

Welcome to Week 24—the culmination of your 6-month, 24-week journey from zero to a production-grade, Principal AI Engineer! You have traversed:

  • Month 1 (Weeks 1–4): Terminal, Git, Advanced Python, SQL Internals, AsyncIO, and the SRE Runbook Copilot CLI.
  • Month 2 (Weeks 5–8): Deep Learning Math, Attention Mechanics, Tokenization, Prompt Engineering, LLM-as-a-Judge, and the Automated LLM Evaluation & Regression Suite.
  • Month 3 (Weeks 9–12): Embeddings, Vector Databases, Chunking Strategies, Dense vs Sparse BM25, Cross-Encoder Rerankers, and the Enterprise Hybrid RAG Engine.
  • Month 4 (Weeks 13–16): ReAct Loops, LangGraph State Machines, PydanticAI, Model Context Protocol (FastMCP), Multi-Agent Teams, Guardrails, and the Agentic MCP Infrastructure Server.
  • Month 5 (Weeks 17–20): High-Concurrency FastAPI, Server-Sent Events (SSE), Redis Chat Memory, OpenTelemetry, Langfuse, Semantic Caching, LiteLLM Cascades, Docker, Next.js Web Chatbot, and the Production FastAPI MLOps Microservice.
  • Month 6 (Weeks 21–24): LoRA Matrix Math, QLoRA NF4 Quantization, DPO Preference Alignment, vLLM PagedAttention, GGUF/Ollama Serving, the Public Educational Web Platform, and Capstone 6: Fine-Tuned Open Model Serving & Benchmark Engine!
