👋 Welcome to CTO Teachings’s blog. While we are a recruiting company, we happen to provide a free blog for people just like you. It’s packed with hard-won lessons from CTO—who’s helped managers rise to Engineering Director and CTO roles.

Let's talk about Claude Code and what it really takes to become an effective AI-powered developer.

It's one thing to be a skilled traditional developer, but nowadays you also need to master Claude coding. You need to get good at what I call "vibe coding," that natural flow between you and the AI.

Breaking down programming problems into clear, logical steps isn't just good practice anymore - it's absolutely essential when working with Claude Code. If you approach a problem trying to change the entire world at once, even Claude Code is going to struggle. And you'll struggle too when you're left reviewing a mess of overly complex code.

The Reality of Working with Claude Code

I recently dove deep into using Claude Code myself to really understand how to leverage it effectively. What I discovered is that there's definitely an art to wrangling Claude Code properly.

Claude Code will make mistakes. Accept this reality upfront. You need to develop strong code review skills, and more importantly, you need to adapt your review process based on your specific context.

If you're launching an MVP, you can get away with a lighter touch during code review. But if you're working at enterprise scale and trying to build something that needs to grow, you need to be careful. Claude Code will start digging you into design holes and architectural debt pretty damn fast if you're not careful.

The Testing Strategy That Actually Works

Having comprehensive tests is absolutely critical when working with Claude Code - especially since Claude can write them for you. Unless you're a very early-stage startup (month one or two), there's no excuse.

There's a special testing approach that most developers don't know about, which we successfully implemented at Twitter. Test at the API level. When you do this, Claude can refactor internal implementation details without you having to touch your tests. It's incredibly powerful.

The only time you need to update your tests is when you change an API, what we call an "architectural refactor." This approach gives you the confidence to let Claude Code iterate and improve your implementation while maintaining test coverage.

What Claude Code Can Actually Build

Once you master working with Claude Code, the results are genuinely impressive. You can have it code complete features end-to-end, from GUI to database.

Picture this: you want to build a customer management feature. Claude Code can create:

• A clean list view showing all customers

• An "Add Customer" button and form

• A save function that properly persists data

• Individual customer view pages

• All the necessary API endpoints

• Controller logic that follows your established patterns

• Database layer integration

This is where solid architecture becomes incredibly valuable. When you've built clear API patterns in your project, Claude Code picks up on them and keeps that consistency. Instead of generating code that clashes with your existing system, it adapts to your established conventions and extends them naturally.

The Complete Development Workflow

The real magic happens when you set up Claude Code to handle the full development loop. You can have it open a browser, run proper tests, and verify everything works end-to-end. When it finds mistakes, it iterates and fixes them. The workflow becomes remarkably smooth.

The key principles for success:

• Break problems into clear, manageable chunks

• Maintain well-defined architecture and API patterns

• Implement smart testing strategies designed for AI-generated code

• Apply context-appropriate code review practices

• Let Claude Code handle the iteration cycles

Addressing the Token Cost Concern

I know some developers worry about token usage and costs. The reality is that paying a bit more for Claude and hiring fewer developers makes perfect economic sense when you can achieve genuine 5X productivity gains.

The transformation isn't just about generating more code faster; it's about working with Claude Code as a true development partner. When you get this right, you're not just writing code; you're architecting solutions at a completely different level of efficiency.

The developers who figure this out first are going to have a huge competitive advantage.

Finding Developers Who Can Actually Use Claude Code

Once you understand Claude Code yourself, you'll quickly realize that not every developer can use it effectively. Traditional programming interviews don't tell you anything about how someone will work with AI tools.

Introducing Claude Code into your interviews is extremely effective because you really need to see how people are going to work with the tool, rather than just evaluating their traditional programming skills.

I always recommend baselining this process with some of your strongest developers first. Have them go through the interview, use Claude Code in front of you, and you get some idea of what you're looking for when you interview other developers.

The developers who can truly leverage Claude Code are fundamentally different from traditional developers. They understand how to break down problems appropriately, they know when to trust the AI and when to be skeptical, and they can review AI-generated code effectively for their specific context.
