Did You Know That LLMs Can Take Architecture as Code to the Next Level?

Hi everyone! My name is Alexey Pronsky, and I'm an architect in the AI department of a large financial services company. We build agentic systems, AI assistants, OCR systems, speech analytics, and Classic ML models. Since we follow enterprise development principles, every project is backed by a Solution Architecture Document (SAD) — a document that goes through approval with business stakeholders, enterprise architecture, information security, and owners of adjacent systems. We maintain our SADs in Confluence and draw diagrams in Draw.io. The typical cycle from receiving business requirements to an approved SAD takes two to three weeks on average. Over the past year, LLM assistants have revolutionized code writing. In this article, I'll show how to achieve the same effect in architecture — by adopting the Architecture as Code approach and delegating the routine to an LLM. We use Structurizr to describe architecture and Claude Code as our LLM assistant. I'll demonstrate examples based o
