Claude Code: the tool behind this website
What this website is built with
Every page, every table and every validation rule on this website was created with Claude Code, the AI developer tool by Anthropic. Claude Code is an assistant that works directly inside the project: it reads code, writes code, runs tests, finds bugs and builds entire features on request, from first draft to verified delivery. The reports themselves are produced with Claude, the AI models by Anthropic, and pass automated checks before they are published (details in our methodology).
What that means in practice
This website reads official financial reports in multiple formats and languages, extracts sourced figures from them, cross-checks them and publishes them in eight languages, with a clickable source on every number. A project of this size used to be months of team work. With Claude Code it grows in dialogue: a finding from a phone review ("this table breaks on small screens") is described, the tool locates the cause in the code, builds the fix, runs the test suites and rebuilds the site, often within minutes. Error classes found once are locked in as automated tests and cannot come back.
What you can achieve with it
Claude Code is not just for software professionals. It helps with a first script as much as with reworking grown systems: your own data analyses, automation of recurring work, websites and tools you cannot buy off the shelf. The decisive difference to a chat window: Claude Code works in your actual files, can run programs, check results and test its own work. You describe the goal, review the outcome and keep every decision in your own hands.
The pairing with Python
Claude Code works especially well together with Python, the language this website is built in. Python is readable enough to follow every suggestion the tool makes, and its ecosystem covers almost everything: reading data, processing tables, parsing PDFs, generating charts, building websites. Claude Code knows these building blocks, writes the code, runs it directly and corrects itself against the result. An idea ("read these hundred reports and collect all revenue figures") becomes a tested, reusable script. Knowing Python does no harm: a basic understanding is useful, and it keeps growing as you work with the tool.
Our experience in one sentence
The limit shifts from "What can I program?" to "What can I describe and verify precisely?": care and judgement remain the human's job, the implementation becomes fast.

Claude Code is made by Anthropic; getting started and documentation at claude.com/claude-code. An account and a terminal are enough for the first steps; the models behind it are the same Claude models available in chat.
