Systems thatgrew by accident,redrawn onpurpose.

…from the first line of code to the cloud bill.

Independent software engineer, DevOps and infrastructure consultant for businesses in Myanmar, Thailand and beyond. I write the software, build the pipeline that ships it, and run the cloud underneath, so one person answers for the whole path from commit to customer.

Detail C · Cloud costRUN

Same platform, a tenth of the bill

฿40,000฿4,000/ month

A phased migration where every step could be rolled back on its own. Nothing went dark, nothing was rewritten for the sake of it.

Detail D · PaymentsBUILD

Four payment routes, one ledger

4routes → 1ledger

Two regional gateways plus Apple and Google in-app billing, reconciled into a single ledger. Prices are decided on the server, so the app can't change what a customer is charged.

Detail E · Open sourceSHIP

DoneWhen: a review gate for AI-built code

65★ on GitHub · AGPL-3.0

A self-hosted tracker where AI agents tick a done-when checklist, and the server refuses to move unfinished work to review. Go, SvelteKit, PostgreSQL and MCP.

Sheet 03 / 07 · StandardWhy engineering still mattersBuilt with AI, or not

AI gave everyone a pencil.
It didn't make them engineers.

AI made software easy to start. An app takes a weekend; a website, an afternoon. That's real, and it's good.

But on day one, a weekend app and an engineered system look the same. The difference shows up on launch day, on the first failed payment, and when the cloud bill arrives.

I use AI every day. It makes me fast. Fourteen years of engineering is what makes it safe.
