I’m currently transitioning into AI Engineering, with a focus on business applications.
So far, I’ve completed the foundational + Python programming sections (1–20) of an AI Engineer bootcamp, covering:
If we want to continue progress in science, we must be prepared to acknowledge that the correct description of nature will eventually simply be too complicated for humans to understand. I do not think it is wise to make human understanding a requirement. AI is the way forward.
Real use: a shared company MCP server where the AI reaches the files it needs and nothing else. Biggest lesson: building agents is as much about trust and boundaries as capability.
Labs 3 & 4: remote servers over streamable HTTP, filesystem roots as security boundaries, and sampling, where the server asks the model for help only after the user approves.
Lab 2: built an MCP server with tools (write/delete files), resources (read files, list dirs) and prompts (code review, docs), plus logging, progress and user elicitation. Real use: an assistant that works in your project folder and asks before deleting anything.
Lab 1: a LangGraph ReAct agent on GPT-5 talking to two MCP servers at once (library docs + Met Museum) over STDIO and HTTP. Real use: a dev assistant that pulls current docs instead of guessing from stale training data.
MCP (Model Context Protocol) is a standard way for AI models to connect to tools, data and prompts. Build a server once, any compatible client can use it. No more custom glue code for every integration.
Course 9 done: "Build AI Agents using MCP." That's 9 of 10 in the IBM RAG and Agentic AI cert. One course left, the capstone, and I'm properly excited. Here's what MCP taught me 🧵
Biggest takeaway: there's no single best framework. The skill is picking the right one for the job, and sometimes combining them.

#AgenticAI#LangGraph#CrewAI#BeeAI#AutoGen
Course 8 done. This one was a tour of the frameworks I'll actually be building with from here: LangGraph, CrewAI, BeeAI and AG2 (AutoGen). Here's what I took from each 🧵
AG2 (AutoGen): built AutoMed, a team of agents simulating a medical consultation. One analyses symptoms, one suggests treatments, one pulls live medical data, one handles follow-up. Not a doctor, but real potential for triage in stretched clinics.
The thread through all three: the leap isn't AI that answers. It's AI that checks itself, corrects itself, and knows when it can't answer.
7 down, 3 to go 🚀
#AgenticAI#LangGraph#LangChain#AIAgents#RAG
Course 7 done: "Agentic AI with LangChain and LangGraph." Last course taught me agents can use tools. This one taught me they can think in loops. Built 3 projects 🧵
That one felt the most real. Upload a 200-page report or a contract, ask a question, get an answer that's been checked rather than just generated. Legal review, dense analyst reports, research where a fake citation is a disaster.
