Proof · Brian Blessou, founder

A whole business system, built alone with AI agents.

Your Bike in Bali is a scooter rental business that sells and runs over WhatsApp. I built every part of its software as the only human developer, working with AI coding agents under strict guardrails. It runs the business every day.

What it proves

Three problems, already solved once.

The same work, seen from three sides.

You have developers

AI writes code your team can trust

54 written code rules, each enforced by the pipeline or an AI review agent
Every change: green pipeline, AI review and owner approval before it merges
Security scans on every change: secrets, code, packages, images
2,390 backend tests at 85.4% coverage, 363 browser tests

You have no dev team

A full product, without a full team

AI chat pipeline, operations web app, website, ads measurement
Website: 98 pages in 7 languages
Serverless AWS, all in Terraform: 100 resources
51 releases with automatic rollback

You want AI on your data

AI that reads your messages and drafts the reply

AI drafts sent unchanged: from about 1 in 8 to 67.8% in 7 weeks
3 AI providers benchmarked on 22 real chats before choosing
Guardrails hold any draft with a wrong price, time or language
$0.0066 per message read, $0.0124 per draft
