This is what the site does — answers questions through conversation. Here's a taste of how it works, right on this page.

The Anthropic workflow — from architecture to deployment.

Every site I build uses Claude as a pair-programming partner. Not copy-paste from ChatGPT — a genuine collaborative workflow where the AI understands the full architecture and makes informed decisions alongside me.

Architecture

Claude helps design the system before any code is written. We discuss trade-offs between SSR and SSG, debate database schemas, map out API routes. The AI sees the full picture — not just the file I'm editing. Every architectural decision is reasoned through, not guessed at.

Pair Programming

Real-time collaboration. I describe what I need, Claude writes the implementation. I review, adjust, push back. It's not about generating code — it's about having a second brain that remembers every dependency, every edge case, every decision we made three hours ago.

Chatbot Engineering

Training AI personas is its own discipline. System prompts are 2,000+ tokens of carefully structured personality, knowledge boundaries, anti-hallucination rules, and voice guidelines. Claude helps write prompts that make another AI behave correctly. It's AI training AI.
