Every article so far has used one Claude Code session. One terminal, one conversation, one context. That works for small projects, but what about larger codebases where different parts can be built in parallel? Claude Code supports multiple agents working on the same project. You can have one agent building the backend, another building the frontend, and a third writing tests — all at the same time. This article tests whether multi-agent development actually works. Does it save time? What happens when agents step on each other’s code? How do you coordinate? ...

Welcome to Part 3: Advanced Projects. We are done with quick builds and half-day apps. Now we tackle complex, multi-component systems. First up: a real-time chat application. WebSockets, authentication, rooms, typing indicators, online presence, message history. This is the kind of project that tests whether Claude can handle multiple moving parts that all need to work together in real time. Total time: 4 hours 38 minutes. 7 prompts. WebSocket auth was the hardest part. ...

Building a desktop application is different from building a web app. You have to deal with the operating system: file dialogs, menu bars, keyboard shortcuts, window management. Electron makes this possible with web technologies, but the architecture — main process vs. renderer process — trips up many developers. Can Claude handle it? I gave it a full markdown editor spec and found out. Total time: 3 hours 47 minutes. 7 prompts. Electron’s IPC was the biggest time sink. ...

API integration is one of the things developers do most and enjoy least. Parsing JSON, handling errors, managing loading states, formatting data for charts. It is repetitive work. This is where Claude Code earns its keep. I gave it an API, a design goal, and a list of features. It handled the rest. Total time: 2 hours 38 minutes. 6 prompts. The charts took the longest. What We’re Building A weather dashboard with: ...

Welcome to Part 2 of the series. The Quick Builds are done. Now we build real applications — the kind that take a full afternoon and have multiple moving parts. First up: a full-stack blog platform. Not a static site. A real blog with a database, admin panel, markdown editor, authentication, and SEO features. The kind of project that would normally take a weekend. Total time: 3 hours 22 minutes. 7 prompts. A lot of debugging auth. ...
