Salon OS, ChatStall, NOIR, and Architecture Studio each get a full case study (problem, flow, interface, system) with a working interactive prototype embedded in the page, not just screenshots.

Each case study documents the actual architecture behind it — data model, integrations, responsive approach — scoped the way a real engagement would be, not written as marketing copy.

The office-to-desktop experience you're in right now — a real state machine, a custom drag/resize window manager, dialogue-driven routing — is its own proof of execution, not a template.

Sign-in and sessions run on Supabase Auth, with access scoped per account — a business only sees its own storefront and orders, a creator only their own campaigns and payouts.

ChatStall is multi-tenant — each merchant's storefront, catalog, and orders are scoped to that merchant's own account, whether they're on a shared subdomain or their own connected custom domain.

Both products run on Supabase-managed Postgres, which includes automatic backups — not a manual process someone has to remember to run.

Cashfree payment and UPI payout webhooks are signature-verified on arrival, and failed or duplicate events are logged and handled rather than silently dropped.

Production errors are tracked and logged, so a failure surfaces on its own instead of waiting for a user to report it.
