I build pages for a live store, where a bad release costs sales rather than a quick undo.

In code: Liquid theme sections and templates.

I moved customers’ birthday months out of free-text notes into proper fields. It previews every change before it writes one.

In code: a metafield backfill on the Admin GraphQL API, with the dry run as the default.

Six commits on 19 August 2026 fixed the search page, the search-as-you-type box and the suggestions.

In code: two Liquid snippets that post-filter the platform’s semantic results.

The slow-seller engine gives merchandising one recommendation per style, from live sales.

Primarily engineered by Kirei Kharisma Handayani↗ — LinkedIn profile, opens in a new tab. I defined what it had to do, reviewed the implementation, and took it through QA and rollout.

When the store and the apps around it disagree, I find out why.

In practice: Admin GraphQL query cost, OAuth token lifetimes, and app figures that disagree with the store’s own data.

I owned releases and store checks: verify against real orders, and write down what was deliberately not changed.
