The brief.
Stuart needed a single platform that did three things at once: showcase his film and ad scoring portfolio with persistent audio playback, sell sample packs and stems through a real checkout, and let him publish new work without engineering involvement. Existing template solutions broke at the persistent-audio requirement; existing storefronts broke at the audio-portfolio requirement.
The architecture.
A Next.js App Router build with Server Components for the catalogue and a single Client Component island for the persistent audio player, lifted to the root layout so it survives navigation. Supabase handles auth, product catalogue, order records, and asset storage with row-level security policies. Razorpay handles checkout. The admin dashboard is a separate authenticated route that lets Stuart upload tracks, set prices, and ship sample packs without writing code.
What I hardened before handover.
- Supabase RLS policies for every table.
- Rate limiting on the inquiry form and checkout endpoints.
- Full audit logging for admin actions.
- A security dossier delivered as a separate document.
- Contracts under the Indian Contract Act and DPDP Act 2023.
