I build web apps that ship

Eight apps of my own, built and shipped solo, for Shopify, Chrome, Adobe Express, WordPress and Google Docs.

Products

Fieldloader, Linkstamp, Sequent and Keyword Lantern are published in their stores, with four on the way.

  • Fieldloader's import preview in the Shopify admin: five values would change, each listed with its line number, what the variant holds now and what it would become.

    Fieldloader

    Bulk edit Shopify variant and product metafields by CSV, with a preview before anything is written.

Who makes these

I'm Ryan Koning, a developer in Winschoten, in the Netherlands. I work with Next.js and TypeScript, and I'm fluent in English and Dutch.

Every app on this page is mine end to end: the idea, the code, the listing and the support address. Four of the eight are published, each built solo from first commit to approval.
