Spine — Property & Business SaaS

Problem

Property and business operators (malls, farms, and multi-location businesses) need tenant-isolated dashboards, reporting, and AI assistance without standing up separate infrastructure per client.

Approach

Built a multi-tenant SaaS as 5 Next.js apps (mall, farm, biz, super-dashboard, and tenant portal) in a Turborepo monorepo, with Supabase row-level security isolating each tenant's data.

Tech highlights

Turborepo + pnpm workspaces across 5 Next.js 14 apps; Supabase RLS for tenant isolation; Deno Edge Functions for cron-triggered automation; AI chat via Anthropic Claude with Mistral fallback through the Vercel AI SDK; @react-pdf/renderer for report generation; Apache Superset for analytics dashboards.

Results

Running across multiple internal apps in active development — full write-up and demo coming soon.

Challenges

Enforcing strict tenant isolation across 5 apps sharing one Supabase instance — getting row-level security policies right so no query could ever leak data between tenants — while keeping shared Turborepo packages, types, and Supabase migrations in sync so a change in one app didn't silently break the others.
