Claude Code in practice: how we use it at Andronia
I am not a professional developer. I cannot write Python code, I never studied computer science, and just a year ago the terminal window still felt alien to me.
Yet at Andronia, I built almost every internal tool myself, from customer acquisition to contract generation. I built them with Claude Code.
What is Claude Code?
Claude Code is Anthropic’s command-line AI development tool. It is not a chatbot. It is not code completion. It is an AI that works on your computer: it reads and writes files, runs commands, fixes errors, and builds complex projects step by step.
What sets it apart from other AI coding tools is that Claude Code genuinely understands context. It does not suggest isolated snippets; it carries a task from start to finish. It understands the project’s structure, remembers earlier decisions, and can search for the cause on its own when something does not work.
How we use it in practice
It has become indispensable in three areas.
Customer acquisition system
Our entire AI-based lead generation process was built with Claude Code. The system automatically collects data on potential customers, generates personalized emails, and tracks results. Work that would previously have taken me days by hand is now done in minutes.
The specific setup: Python scripts that communicate with external services through APIs, Google Sheets integration for reporting, and automated workflows that connect everything. Claude Code wrote all of it; I explained what I wanted to achieve.
Document generation
We generate contracts, proposals, and PDFs automatically. I provide the template structure and customer data, and the system produces the finished document in minutes, complete with the correct formatting, logo, and legal text.
This is not simple template filling. The system is bilingual, in Hungarian and English, handles conditional blocks with different wording for different services, and produces a professional PDF that we can send directly to the customer.
This blog
Yes, this blog was built with Claude Code too. Claude Code set up the Astro framework, Webflow integration, SEO settings, navigation, and styles. I described how it should look, and we worked through the project together.
What works
Three things stand out.
Understanding context. Claude Code does not forget. Once you explain how your project is structured, it knows the next time. You do not have to repeat the basics over and over.
Debugging. If something does not work, Claude Code reads the error message, understands the cause, and fixes it. I have not had to open a single Stack Overflow question in the past few months.
Handling complexity. I have used it to build systems that would previously have required hiring a developer. Not because Claude Code is perfect, but because it patiently works through every step until the final result is what I asked for.
What does not work
Let us be honest.
It does not replace thinking. Claude Code does what you ask. If you frame the request badly, you get a bad result. It is still your job to know what you want to build and why.
It sometimes overcomplicates things. If you are not careful, it tends to add unnecessary features “just to be safe.” You have to learn to rein it in and insist on the simple solution.
Hungarian is a challenge. Most AI tools are optimized for English. They work in Hungarian too, but you need to check the language carefully. I always review the text before anything becomes public.
Who do I recommend it to?
If you have a specific business problem that needs software, but you have neither a developer nor the budget for one, Claude Code is a genuine alternative. You do not have to be a programmer. You only need to be able to explain what you want to achieve.
At the same time, it is not a magic wand. You have to spend time with it, learn how to communicate with it effectively, and take responsibility for the result. But if you are willing to do that, you gain access to tools that only larger companies could previously afford.
How do you get started?
You can try Claude Code with a Pro subscription. Install it, open the terminal, and start describing what you want. Make your first project something simple: a script that automates a repetitive task, or a basic website.
The most important advice I can give is this: do not focus on the code. Focus on what you want to achieve, and let AI handle the technical details.
If you want to see what a system like this looks like in practice, or you want help with your first automation, write to us. We are happy to show you what works and what does not.
