Building Your Second Brain I want to put something in your hands this week that I genuinely believe is one of the highest-leverage things you can build right now. A second brain — an AI-powered knowledge base that reads everything you feed it once, then builds and maintains a living, interconnected library of your knowledge for you. You stop re-explaining yourself to AI. It already knows your work, your projects, your thinking — and it gets smarter every time you add to it. This is Andrej Karpathy's "LLM Wiki" idea, and here's why it matters for you specifically. 🌍 Why this matters as you transition into the workforce The job market isn't rewarding people who can use AI. Everybody can open a chatbot. It's rewarding people who can architect with it — who build systems rather than ask one-off questions. That's the whole difference between "a prompt engineer who asks ChatGPT for code" and "a system designer who uses AI as a force multiplier." One is replaceable. The other gets hired. When you build your own second brain, three things happen: 🧩 You demonstrate AI fluency — the exact skill every forward-looking employer is screening for. You don't just talk about it; you show it. 📈 Your knowledge compounds. Every note, transcript, and lesson you add makes the whole thing more valuable. That's an asset that grows while you sleep. 🎯 You stand out. Most people consume AI. You'll be one of the few who design with it. That's the portfolio piece and the interview story. This isn't theory. I built mine over the last few days, and it now holds 600+ pages of my entire body of work — and I can talk to it from Slack like a coworker. 🛠️ What you're building (and the part I want you to hear) Three pieces: 1. Obsidian — a free app that holds your knowledge as simple text files. This is your "vault." 2. Claude — the AI that reads your stuff and builds & maintains the wiki for you. You barely touch it; the AI does the bookkeeping humans always abandon. 3. An agent (connected through Slack or Telegram) — so you can ask your second brain anything, from anywhere, anytime. Mine's named Blake. He lives in my team channel and answers from my brain 24/7.

No one is reading your case studies anymore. Recruiters are spending 55 seconds looking at portfolios. This excellent video discussing the new shift in portfolios and how to restructure yours! I will be updating mine and taking a lot of inspiration from this video myself. Stay tuned to see how I update mine!

Google has released a free AI Professional Certificate that has been getting some praise online. I will be taking a look at this certification myself and I recommend you all as well. https://grow.google/enroll-certificates/ai-professional-certificate-mid/
