From Zero to Production: How 15 Engineers Shipped a Production LLM Product with AI Coding Tools

How a team of fewer than 15 engineers at MYOB took an AI-powered chat experience from zero to production, embedded directly inside the product serving real small business owners and accountants. Leaning heavily into AI-assisted coding throughout the entire development lifecycle, using tools like Cursor and Claude Code as genuine force multipliers. Covers the AI Engineering challenges of productionising LLM features at scale — evaluation, guardrails, latency, hallucination management — and what it actually looks like when a small team uses AI coding tools to ship faster than anyone expected.
