As a Vue 3 dev with no Next.js experience, I built a full-stack CDK selling platform using Codex in 2.5 days — honest experience
I'm a Vue 3 developer who had never worked with Next.js before. Over a few spare evenings at work, I used Codex to build a complete full-stack platform for managing and selling ChatGPT Plus card keys (CDK).
What impressed me most:
Codex handled complex backend logic exceptionally well — webhook verification, inventory race conditions, atomic transactions, and other edge cases were managed automatically with almost no hand-holding.
UI challenge and the fix that made a big difference:
Out of the box, the generated layouts relied heavily on cards and quickly became messy. I applied a specific UI/UX refinement skill that cleaned everything up significantly. If design matters to you, I highly recommend checking it out: https://github.com/nextlevelbuilder/ui-ux-pro-max-skill
Final outcome:
The platform is now fully live and functional. It was a valuable practical exercise in transitioning from Vue to Next.js with AI assistance. If you're a Vue developer exploring Codex, I'd be interested to hear your experiences too.
