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.
